Fungal Quotes

There are more life forms in a handful of forest soil than there are people on the planet. A mere teaspoonful contains many miles of fungal filaments. All these work the soil, transform it, and make it so valuable for the trees.

I don’t think that’s it. I think everybody’s got that special someone that gets under their skin and doesn’t go away. I think maybe you have that particular fungal property for him.

We found that trees could communicate, over the air and through their roots. Common sense hooted us down. We found that trees take care of each other. Collective science dismissed the idea. Outsiders discovered how seeds remember the seasons of their childhood and set buds accordingly. Outsiders discovered that trees sense the presence of other nearby life. That a tree learns to save water. That trees feed their young and synchronize their masts and bank resources and warn kin and send out signals to wasps to come and save them from attacks. “Here’s a little outsider information, and you can wait for it to be confirmed. A forest knows things. They wire themselves up underground. There are brains down there, ones our own brains aren’t shaped to see. Root plasticity, solving problems and making decisions. Fungal synapses. What else do you want to call it? Link enough trees together, and a forest grows aware.

The mycorrhizae may form fungal bridges between individual trees, so that all the trees in a forest are connected. These fungal networks appear to redistribute the wealth of carbohydrates from tree to tree. A kind of Robin Hood, they take from the rich and give to the poor so that all the trees arrive at the same carbon surplus at the same time. They weave a web of reciprocity, of giving and taking. In this way, the trees all act as one because the fungi have connected them. Through unity, survival. All flourishing is mutual. Soil, fungus, tree, squirrel, boy—all are the beneficiaries of reciprocity.

Todd? Are you still there?" "Yeah. I'm just trying to think of a good reason to continue our friendship." I grinned. "Jealousy is so unattractive Todd." "It would help if you could tell me one thing that's wrong. One flaw. Bad breath? Warts? Some condition that requires anti fungal spray?" "Would chest hair be a flaw?" "Oh, yeah." Todd sounded relieved." I can't stand a chest rug. You can't see the chest cut.

Yeah, but I thought mushrooms were a kind of fungus!' Teddy says. 'You know, like mould. You can't get mould growing on mould, can you? It'd be like a weird incestuous fungal party.

Our ports wouldn't have backlogs if our supply chains, distribution systems and transportation systems mimicked fungal networks.

Some fungi have tens of thousands of mating types, approximately equivalent to our sexes (the record holder is the split gill fungus, Schizophyllum commune, which has more than twenty-three thousand mating types, each of which is sexually compatible with nearly every one of the others). The mycelium of many fungi can fuse with other mycelial networks if they are genetically similar enough, even if they aren’t sexually compatible. Fungal self-identity matters, but it is not always a binary world. Self can shade off into otherness gradually.

Without this fungal web my tree would not exist. Without similar fungal webs no plant would exist anywhere. All life on land, including my own, depended on these networks.

He stretched, ate his last bite of fungal curds, drank the dregs of something not entirely unlike coffee, and headed out to keep peace in wartime.

At Mayflower-Plymouth, our purpose is to help businesses fulfill solutions and solve problems concerning the allocation of capital. And we do that by modelling mycelium fungal networks.

When trying to understand the interactions of nonhuman organisms, it is easy to flip between these two perspectives: that of the inanimate behavior of preprogrammed robots on the one hand, and that of rich, lived human experience on the other. Framed as brainless organisms, lacking the basic apparatus required to have even a simple kind of “experience,” fungal interactions are no more than automatic responses to a series of biochemical triggers. Yet the mycelium of truffle fungi, like that of most fungal species, actively senses and responds to its surroundings in unpredictable ways.

It was a fungal party hellscape.

Fungi are equipped with different kinds of bodies. They don’t have noses or brains. Instead, their entire surface behaves like an olfactory epithelium. A mycelial network is one large chemically sensitive membrane: A molecule can bind to a receptor anywhere on its surface and trigger a signaling cascade that alters fungal behavior.

For Adamatzky, the point of fungal computers is not to replace silicon chips. Fungal reactions are too slow for that. Rather, he thinks humans could use mycelium growing in an ecosystem as a “large-scale environmental sensor.” Fungal networks, he reasons, are monitoring a large number of data streams as part of their everyday existence. If we could plug into mycelial networks and interpret the signals they use to process information, we could learn more about what was happening in an ecosystem.

Through the genius of evolution, the Earth has selected fungal networks as a governing force managing ecosystems.

How in the name of ash and talon did that fucking Vidona fit a fucking fungal canister on a fucking bannermoth?

fungal networks form physical connections between plants. It is the difference between having twenty acquaintances and having twenty acquaintances with whom one shares a circulatory system.

Fungi constitute the most poorly understood and underappreciated kingdom of life on earth. Though indispensable to the health of the planet (as recyclers of organic matter and builders of soil), they are the victims not only of our disregard but of a deep-seated ill will, a mycophobia that Stamets deems a form of “biological racism.” Leaving aside their reputation for poisoning us, this is surprising in that we are closer, genetically speaking, to the fungal kingdom than to that of the plants. Like us, they live off the energy that plants harvest from the sun. Stamets has made it his life’s work to right this wrong, by speaking out on their behalf and by demonstrating the potential of mushrooms to solve a great many of the world’s problems.

Mycelium is ecological connective tissue, the living seam by which much of the world is stitched into relation. In school classrooms children are shown anatomical charts, each depicting different aspects of the human body. One chart reveals the body as a skeleton, another the body as a network of blood vessels, another the nerves, another the muscles. If we made equivalent sets of diagrams to portray ecosystems, one of the layers would show the fungal mycelium that runs through them. We would see sprawling, interlaced webs strung through the soil, through sulfurous sediments hundreds of meters below the surface of the ocean, along coral reefs, through plant and animal bodies both alive and dead, in

n the wake of catastrophes, fungal diversity helps restore devastated habitats. Evolutionary trends generally lead to increased bio-diversity. However, due to human activities we are losing many species before we can even identify them. In effect, as we lose species, we are experiencing devolution--turning back the clock on biodiversity, which is a slippery slope toward massive ecological collapse. The interconnectedness of life is an obvious truth that we ignore at our peril.

Trees don't rely exclusively on dispersal in the air, for if they did, some neighbors would not get wind of the danger. Dr. Suzanne Simard of the University of British Columbia in Vancouver has discovered that they also warn each other using chemical signals sent through the fungal networks around their root tips, which operate no matter what the weather. Surprisingly, news bulletins are sent via the roots not only by means of chemical compounds but also by means of electrical impulses that travel at the speed of a third of an inch per second. In comparison with our bodies, it is, admittedly, extremely slow. However there are species in the animal kingdom, such as jellyfish and worms, whose nervous systems conduct impulses at similar speed. Once the latest news has been broadcast, all oaks int he area promptly pump tannins through their veins.

Fungi are veteran survivors of ecological disruption. Their ability to cling on—and often flourish—through periods of catastrophic change is one of their defining characteristics. They are inventive, flexible, and collaborative. With much of life on Earth threatened by human activity, are there ways we can partner with fungi to help us adapt? These may sound like the delirious musings of someone buried up to their neck in decomposing wood chips, but a growing number of radical mycologists think exactly this. Many symbioses have formed in times of crisis. The algal partner in a lichen can’t make a living on bare rock without striking up a relationship with a fungus. Might it be that we can’t adjust to life on a damaged planet without cultivating new fungal relationships

Is it odd to see a book within a book? It shouldn’t be. Books like each other. We understand each other. You could even say we are all related, enjoying a kinship that stretches like a rhizomatic network beneath human consciousness and knits the world of thought together. Think of us as a mycelium, a vast, subconscious fungal mat beneath a forest floor, and each book a fruiting body. Like mushrooms, we are a collectivity. Our pronouns are we, our, us.

Being a tree, affirmation would feel different. Love would feel different. We would be happiest if our soil was full of microbes chatting. We would be happiest if the soil was rich enough to contain a complex fungal network that would allow us to sort of blur into it and talk to or just sort of be each other.

This is ridiculous, she thought. I’m possessed of terrifying powers. Why am I relying on a ridiculous little gun that I picked because I thought it was cute? I don’t need this thing. She threw it contemptuously over her shoulder. Damn right! I took out a house of weird fungal cultists that had devoured three teams of supernatural SWAT teams. I am a badass. She paused and expanded her senses outward, searching for any kind of life. Okay, nothing. At least, she thought uneasily, nothing that I can detect. But then why does it smell so bad down here? There’s something foul wandering the underground tunnels beneath my

Like a bad fungal infection that you just couldn't get rid of no matter how hard you tried, he came back.

Fungal infections were being seen during COVID-19.

It’s dirty and wormholed, colonized with mold, as though fungal hyphae, time, and water have collaborated to make an erasure poem.

from a different fungal species. More than a million exist on earth, about six times the number of plant species, with only about 10 percent of fungal species identified

Patience is the blue vitriol to control the fungal emotions of life

There is a plant called the ghost pipe, because it is ghostly white, almost blue. Were you to cut open this flower and study it, you'd find no chlorophyll inside. It can grow in the dark, under the cover of fallen leaves and undergrowth in forests, under soil. It doesn't need to photosynthesize, because it is a parasite. It uses fungal networks to suck energy from photosynthesizing trees. Its roots look like clusters of tiny fingers that grope toward and connect with huge white webs of fungus that in turn connect with the thick roots of trees.

Envisioning fungi as nanoconductors in mycocomputers, Gorman (2003) and his fellow researchers at Northwestern University have manipulated mycelia of Aspergillus niger to organize gold into its DNA, in effect creating mycelial conductors of electrical potentials. NASA reports that microbiologists at the University of Tennessee, led by Gary Sayler, have developed a rugged biological computer chip housing bacteria that glow upon sensing pollutants, from heavy metals to PCBs (Miller 2004). Such innovations hint at new microbiotechnologies on the near horizon. Working together, fungal networks and environmentally responsive bacteria could provide us with data about pH, detect nutrients and toxic waste, and even measure biological populations.

As he ran through the dense understory, he could read the signs of arboreal intrigue, the drama and power struggles as species vied for control over a patch of sunlight, or giant firs and fungal spores opted to work together for their mutual benefit. He could see time unfolding here, and history, embedded in the whorls and fractal forms of nature, and he would come home, sweating and breathless, and tell her what he’d seen.

This Mother Tree was the central hub that the saplings and seedlings nested around, with threads of different fungal species, of different colors and weights, linking them, layer upon layer, in a strong, complex web

Frank went on to tell me that much of the premise of Dune—the magic spice (spores) that allowed the bending of space (tripping), the giant worms (maggots digesting mushrooms), the eyes of the Freman (the cerulean blue of Psilocybe mushrooms), the mysticism of the female spiritual warriors, the Bene Gesserits (influenced by tales of Maria Sabina and the sacred mushroom cults of Mexico)—came from his perception of the fungal life cycle, and his imagination was stimulated through his experiences with the use of magic mushrooms.

Nature, too, seems increasingly better understood in fungal terms: not as a single gleaming snow-peak or tumbling river in which we might find redemption, nor as a diorama that we deplore or adore from a distance – but rather as an assemblage of entanglements of which we are messily part.

Tshepo reckons that it is inevitable that one’s circle of friends will become smaller as one grows older. He reasons that when we begin we are similar, like two glasses of water sitting side by side on a clean tray. There is very little that differentiates us. We are simple beings whose interests do not extend beyond playing touch and kicking balls. However, like the two glasses of water forgotten on a tray in the reading room, we start to collect bits. Bits of fluff, bits of a broken beetle wing, bits of bread, bits of pollen, bits of shed epithelial cells, bits of hair, bits of toilet paper, bits of airborne fungal organisms, bits of bits. All sorts of bits. No two combinations the same. Just like with the glasses of water, Environment, jealous of our fundamentality, bombards our basic minds with complexity. So we become frighteningly dissimilar, until there is very little that holds us together.

So, let's get back to why the roots are the most important part of a tree. Conceivably, this is where the tree equivalent of a brain is located. Brain? you ask. Isn't that a bit farfetched? Possibly, but now we know that trees can learn. This means they must store experiences somewhere, and therefore, there must be some kind of a storage mechanism inside the organism. Just where it is, no one knows, but the roots are the part of the tree best suited to the task. The old spruce in Sweden also shows that what grows underground is the most permanent part of the tree-and where else would it store important information over a long period of time? Moreover, current research shows that a tree's delicate root networks is full of surprises. It is now an accepted fact that the root network is in charge of all chemical activity in the tree. And there's nothing earth shattering about that. Many of our internal processes are also regulated by chemical messengers. Roots absorb substances and bring them into the tree. In the other direction, they deliver the products of photosynthesis to the tree's fungal partners and even route warning signals to neighboring trees. But a brain? For there to be something we would recognize as a brain, neurological processes must be involved, and for these, in addition to chemical messages, you need electrical impulses. And these are precisely what we can measure in the tree, and we've been able to do so since as far back as the nineteenth century. For some years now, a heated controversy has flared up among scientists. Can plants think? Are they intelligent?

But even if you do not have SIBO or SIFO, it is likely—virtually guaranteed—that you have, at the very least, dysbiosis. Substantial disruptions of the bacterial and perhaps fungal species inhabiting your colon still pose implications for health, whether or not you are regular or require a stack of magazines for bowel habit success.

He says I was around five and crying and was vividly red in the cold spring air. I was saying something over and over; he couldn’t make it out until our mother saw me and shut down the tiller, ears ringing, and came over to see what I was holding out. This turned out to have been a large patch of mold—Orin posits from some dark corner of the Weston home’s basement, which was warm from the furnace and flooded every spring. The patch itself he describes as horrific: darkly green, glossy, vaguely hirsute, speckled with parasitic fungal points of yellow, orange, red. Worse, they could see that the patch looked oddly incomplete, gnawed-on; and some of the nauseous stuff was smeared around my open mouth. ‘I ate this,

Using a holistic, Eastern philosophy, leaky gut can be classified into four categories: candida gut, a fungal condition caused by too much fluid buildup in the body; stressed gut, caused by overwhelming presence of stress hormones; immune gut, caused by emotional pain and grief; and gastric gut, caused by overeating, bad chewing habits, and emotional turmoil.

When Olsson inserted the microelectrodes into Armillaria’s hyphal strands, he detected regular action potential–like impulses, firing at a rate very close to that of animals’ sensory neurons—around four impulses per second, which traveled along hyphae at a speed of at least half a millimeter per second, some ten times faster than the fastest rate of fluid flow measured in a fungal hypha.

Aminotriazole (herbicide used on cranberry crops, causing the “cranberry scare’” of 1959) DDT (widely known after Rachel Carson’s book, Silent Spring) Nitrites (a meat preservative and color and flavor enhancer used in hot dogs and bacon) Red Dye Number 2 Artificial sweeteners (including cyclamates and saccharin) Dioxin (a contaminant of industrial processes and of Agent Orange, a defoliant used during the Vietnam War) Aflatoxin (a fungal toxin found on moldy peanuts and corn)

Living cells must have food in the form of sugar, they must breathe, and they must grow, at least a little. But without leaves-and therefore without photosynthesis-that's impossible. No being on the planet can maintain a centuries-long fast, not even the remains of a tree, and certainly not a stump that has had to survive on its own. It was clear that something else was happening with this stump. It must be getting assistance from neighboring trees, specifically from their roots. Scientists investigating similar situations have discovered that assistance may either be delivered remotely by fungal networks around the root tips-which facilitate nutrient exchange between trees-or the roots themselves may be interconnected. In the case of the stump I had stumbled upon, I couldn't find out what was going on, because I didn't want to injure the old stump by digging around it, but one thing was clear: the surrounding beeches were pumping sugar to the stump to keep it alive.

Mushrooms are only a small part of fungal anatomy. A mushroom is just how a fungus has sex.” Maisie’s slim eyebrows arched high. “Oh, really,” she said. “It’s true. A single fungus in a forest like this can go on for miles, underground, wrapping itself around tree roots. The mushrooms are just its reproductive parts. Fungi are some of the largest living things on Earth. Each tendril is nearly microscopic, but put together they can weigh far more than any California redwood or blue whale.

According to one estimate, the average urban dweller inhales some twenty billion foreign particles every day. Dust, industrial pollutants, pollen, fungal spores, whatever is adrift on the day's air. A lot of this stuff can make you very ill, but it doesn't by and large because your body is normally adept at challenging intruders. If an invading particle is big or especially irritating, you will almost certainly cough or sneeze it straight back out again, often in the process making it someone else's problem.

The plant roots enter into symbiotic relationships with bacteria, fungi, and other plants that are highly sophisticated. Bacteria form colonies on roots systems and produce nitrogen nodules, which the plant can then use as a nitrogen source, something the plants cannot do on their own. And in exchange the bacteria gain nutrients they need to survive. Roots also form close attachments with fungal mycelia. In fact, most plant roots are part of a sophisticated root/fungus communal network that can extend over miles.

Long-range missiles with hybrid thermonuclear and necromantic payloads. Grafted and crossbred infantry divisions. Strategic alliances with folkloric, extraplanar, and subterranean entities. Field deployment of weaponized paleofauna. Large-scale saturation of target areas with invasive fungal and floral xeno organisms. Megadeaths and mega-undeaths. This is the Cold War now. An American president must be found who, whatever his other qualifications, is prepared to maintain our competitiveness in this area. I’m afraid that that person is you.

Elms are dying all over the place, it's Dutch elm disease. [...] It came from America on a load of logs, and it's a fungal disease. That makes it sound even more as if it might be possible to do something. The elms are all one elm, they are clones, that's why they are all succumbing. No natural resistance among the population, because no variation. Twins are clones, too. If you looked at an elm tree you'd never think it was part of all the others. You'd see an elm tree. Same when people look at me now: they see a person, not half a set of twins.

The impact of fungal diseases is increasing across the world: Unsustainable agricultural practices reduce the ability of plants to form relationships with the beneficial fungi on which they depend. The widespread use of antifungal chemicals has led to an unprecedented rise in new fungal superbugs that threaten both human and plant health. As humans disperse disease-causing fungi, we create new opportunities for their evolution. Over the last fifty years, the most deadly disease ever recorded—a fungus that infects amphibians—has been spread around the world by human trade.

The corollary is that a book is not finished until it is read. The writing is not complete until what is said has passed from the physical volume which gives it sensory reality into another mind where it kindles thoughts and impressions: a whole understanding of what it means to be, ignited on foreign soil in an act that is either erotic or imperialistic, but in either case miraculous. We become one another. Ink on paper is the frozen matter of a person, a snapshot of selfhood in fungal spores waiting to be quickened in our borrowed mentation, thought shaping itself in us, of us, to emerge from us.

Even in a forest, there are loners, would-be hermits who want little to do with others. Can such antisocial trees block alarm calls simply by not participating? Luckily, they can't. For usually there are fungi present that act as intermediaries to guarantee quick dissemination of news. These fungi operate like fiber-optic Internet cables. Their thin filaments penetrate the ground, weaving through it in almost unbelievable density. One teaspoon of forest soil contains many miles of these "hyphae." Over centuries, a single fungus can cover many square miles and network an entire forest. The fungal connections transmit signals from one tree to the next, helping the trees exchange news about insects, drought, and other dangers. Science has adopted a term first coined by the journal Nature for Dr. Simard's discovery of the "wood wide web" pervading our forests. What and how much information is exchanged are subjects we have only just begun to research. For instance, Simard discovered that different tree species are in contact with one another, even when they regard each other as competitors. And the fungi are pursuing their own agendas and appear to be very much in favor of conciliation and equitable distribution of information and resources.

A crude map revealed, stunningly, that the biggest, oldest timbers are the sources of fungal connections to regenerating seedlings. Not only that, they connect to all neighbors, young and old, serving as the linchpins for a jungle of threads and synapses and nodes. I’ll take you through the journey that revealed the most shocking aspect of this pattern—that it has similarities with our own human brains. In it, the old and young are perceiving, communicating, and responding to one another by emitting chemical signals. Chemicals identical to our own neurotransmitters. Signals created by ions cascading across fungal membranes.

The main medicinal species that most people use, Prefix-or-not-cordyceps sinensis, is a parasite on caterpillars, specifically the larvae of the ghost moth (which is why it is sometimes called the caterpillar fungus). The fungal spores invade the caterpillar (which lives underground), and they sprout into active mycelia (which spread throughout the caterpillar body via the circulatory system), eventually killing the caterpillar (which then mummifies). The mycelia ultimately fill the corpse, leaving the exoskeleton intact, and the mushroom sprouts from the body (via the head) the next summer, and, hey, we got medicine. (Yum!)

A fungal computer may sound fantastical, but biocomputing is a fast-growing field. Adamatzky has spent years developing ways to use slime molds as sensors and computers. These prototype biocomputers use slime molds to solve a range of geometrical problems. The slime mold networks can be modified—for instance, by cutting a connection—to alter the set of “logical functions” implemented by the network. Adamatzky’s idea of a “fungal computer” is just an application of slime-mold computing to another type of network-based organism. As Adamatzky observes, the mycelial networks of some species of fungus are more convenient for computing than slime molds.

The fungus Shenidioides had originated in Shenzhen, then spread to nearby regions of China. The reigning theory, first disseminated by a prominent doctor in the Huffington Post, was that the new strain of fungal spores had inadvertently developed within factory conditions of manufacturing areas, the SEZs in China, where spores fed off the highly specific mixture of chemicals. To predict the transmission of the fever, the blogger claimed, wind patterns may be analyzed. Not only that, but the holiday traffic surrounding the mass commute of migrant factory workers back to their home villages, such as during Chinese New Year, should also be limited. Traffic carries spores.

As long as we frame a worldview with language that refers to the wild as a commodity, it will be treated as one. It is likewise damaging to invoke technology-based metaphors to explain nature: the brain a computer, the earth a spaceship, the rooted and fungal soil beneath our feet a kind of internet. Such mechanistic phrasing unwittingly invites us to see the natural world as other-than-alive and reparable by human skill in ways that it simply is not. If we are seeking a relationship within the earthen community that is meaningful, genuine, and impactful, then the words we use to describe that relationship, and the beings in its purview, must be chosen with intention, with specificity, with intelligence, and with love.

Lignin is a linkage of three aromatic alcohols—coumaryl, coniferyl, and sinapyl—which fill the spaces in cell walls that are not already occupied by other substances, even ousting water molecules to do so. It thus forms a very strong hydrophobic net, cementing all the cell-wall elements in place and providing strength and rigidity to the xylem. It also provides an important barrier to fungal and bacterial infections. When a tree is invaded by disease, it seals off the infected section with a wall of lignin so that the disease cannot spread. Lignin is so tough that getting rid of it is a costly process in pulp-and-paper plants. The acids needed to break down lignin in pulpwood are the chief pollutants such mills contribute to the environment.

The older trees are able to discern which seedlings are their own kin. The old trees nurture the young ones and provide them food and water just as we do with our own children. It is enough to make one pause, take a deep breath, and contemplate the social nature of the forest and how this is critical for evolution. The fungal network appears to wire the trees for fitness. And more. These old trees are mothering their children. The Mother Trees. When Mother Trees—the majestic hubs at the center of forest communication, protection, and sentience—die, they pass their wisdom to their kin, generation after generation, sharing the knowledge of what helps and what harms, who is friend or foe, and how to adapt and survive in an ever-changing landscape. It’s what all parents do.

The second or third time I watched Stamets show a video of a Cordyceps doing its diabolical thing to an ant—commandeering its body, making it do its bidding, and then exploding a mushroom from its brain in order to disseminate its genes—it occurred to me that Stamets and that poor ant had rather a lot in common. Fungi haven’t killed him, it’s true, and he probably knows enough about their wiles to head off that fate. But it’s also true that this man’s life—his brain!—has been utterly taken over by fungi; he has dedicated himself to their cause, speaking for the mushrooms in the same way that Dr. Seuss’s Lorax speaks for the trees. He disseminates fungal spores far and wide, helping them, whether by mail order or sheer dint of his enthusiasm, to vastly expand their range and spread their message.

She leans back again against the pine’s trunk. Some slight change in the atmosphere, the humidity, and her mind becomes a greener thing. At midnight, on this hillside, perched in the dark above this city with her pine standing in for a Bo, Mimi gets enlightened. The fear of suffering that is her birthright—the frantic need to steer—blows away on the wind, and something else wings down to replace it. Messages hum from out of the bark she leans against. Chemical semaphores home in over the air. Currents rise from the soil-gripping roots, relayed over great distances through fungal synapses linked up in a network the size of the planet. The signals say: A good answer is worth reinventing from scratch, again and again. They say: The air is a mix we must keep making. They say: There’s as much belowground as above. They tell her: Do not hope or despair or predict or be caught surprised. Never capitulate, but divide, multiply, transform, conjoin, do, and endure as you have all the long day of life. There are seeds that need fire. Seeds that need freezing. Seeds that need to be swallowed, etched in digestive acid, expelled as waste. Seeds that must be smashed open before they’ll germinate. A thing can travel everywhere, just by holding still. The next day dawns. The sun rises so slowly that even the birds forget there was ever anything else but dawn. People drift back through the park on their way to jobs, appointments, and other urgencies. Making a living. Some pass within a few feet of the altered woman. Mimi comes to, and speaks her very first Buddha’s words. “I’m hungry.” The answer comes from right above her head. Be hungry. “I’m thirsty.” Be thirsty. “I hurt.” Be still and feel.

A good upbringing is necessary for a long life, but sometimes the patience of the young trees is sorely tested. As I mentioned in chapter 5, "Tree Lottery," acorns and beechnuts fall at the feet of large "mother trees." Dr. Suzanne Simard, who helped discover maternal instincts in trees, describes mother trees as dominant trees widely linked to other trees in the forest through their fungal-root connections. These trees pass their legacy on to the next generation and exert their influence in the upbringing of the youngsters. "My" small beech trees, which have by now been waiting for at least eighty years, are standing under mother trees that are about two hundred years old -- the equivalent of forty-year-olds in human terms. The stunted trees can probably expect another two hundred years of twiddling their thumbs before it is finally their turn. The wait time is, however, made bearable. Their mothers are in contact with them through their root systems, and they pass along sugar and other nutrients. You might even say they are nursing their babies.

Chemical fertilizers, pesticides, insecticides, and fungicides affect the soil food web, toxic to some members, warding off others, and changing the environment. Important fungal and bacterial relationships don’t form when a plant can get free nutrients. When chemically fed, plants bypass the microbial-assisted method of obtaining nutrients, and microbial populations adjust accordingly. Trouble is, you have to keep adding chemical fertilizers and using “-icides,” because the right mix and diversity—the very foundation of the soil food web—has been altered. It makes sense that once the bacteria, fungi, nematodes, and protozoa are gone, other members of the food web disappear as well. Earthworms, for example, lacking food and irritated by the synthetic nitrates in soluble nitrogen fertilizers, move out. Since they are major shredders of organic material, their absence is a great loss. Without the activity and diversity of a healthy food web, you not only impact the nutrient system but all the other things a healthy soil food web brings. Soil structure deteriorates, watering can become problematic, pathogens and pests establish themselves and, worst of all, gardening becomes a lot more work than it needs to be.

, like this: In healthy forests, which we might imagine to exist mostly above ground, and be wrong in our imagining, given as the bulk of the tree, the roots, are reaching through the earth below, there exists a constant communication between those roots and mycelium, where often the ill or weak or stressed are supported by the strong and surplused. By which I mean a tree over there needs nitrogen, and a nearby tree has extra, so the hyphae (so close to hyphen, the handshake of the punctuation world), the fungal ambulances, ferry it over. Constantly. This tree to that. That to this. And that in a tablespoon of rich fungal duff (a delight: the phrase fungal duff, meaning a healthy forest soil, swirling with the living the dead make) are miles and miles of hyphae, handshakes, who get a little sugar for their work. The pronoun who turned the mushrooms into people, yes it did. Evolved the people into mushrooms. Because in trying to articulate what, perhaps, joy is, it has occurred to me that among other things—the trees and the mushrooms have shown me this—joy is the mostly invisible, the underground union between us, you and me, which is, among other things, the great fact of our life and the lives of everyone and thing we love going away. If we sink a spoon into that fact, into the duff between us, we will find it teeming. It will look like all the books ever written. It will look like all the nerves in a body. We might call it sorrow, but we might call it a union, one that, once we notice it, once we bring it into the light, might become flower and food. Might be joy.

Fish at breakfast is sometimes himono (semi-dried fish, intensely flavored and chewy, the Japanese equivalent of a breakfast of kippered herring or smoked salmon) and sometimes a small fillet of rich, well-salted broiled fish. Japanese cooks are expert at cutting and preparing fish with nothing but salt and high heat to produce deep flavor and a variety of textures: a little crispy over here, melting and juicy there. Some of this is technique and some is the result of a turbo-charged supply chain that scoops small, flavorful fish out of the ocean and deposits them on breakfast tables with only the briefest pause at Tsukiji fish market and a salt cure in the kitchen. By now, I've finished my fish and am drinking miso soup. Where you find a bowl of rice, miso shiru is likely lurking somewhere nearby. It is most often just like the soup you've had at the beginning of a sushi meal in the West, with wakame seaweed and bits of tofu, but Iris and I were always excited when our soup bowls were filled with the shells of tiny shijimi clams. Clams and miso are one of those predestined culinary combos- what clams and chorizo are to Spain, clams and miso are to Japan. Shijimi clams are fingernail-sized, and they are eaten for the briny essence they release into the broth, not for what Mario Batali has called "the little bit of snot" in the shell. Miso-clam broth is among the most complex soup bases you'll ever taste, but it comes together in minutes, not the hours of simmering and skimming involved in making European stocks. As Tadashi Ono and Harris Salat explain in their book Japanese Hot Pots, this is because so many fermented Japanese ingredients are, in a sense, already "cooked" through beneficial bacterial and fungal actions. Japanese food has a reputation for crossing the line from subtlety into blandness, but a good miso-clam soup is an umami bomb that begins with dashi made from kombu (kelp) and katsuobushi (bonito flakes) or niboshi (a school of tiny dried sardines), adds rich miso pressed through a strainer for smoothness, and is then enriched with the salty clam essence.

There are two key moves by which fungal hyphae become a mycelial network. First, they branch. Second, they fuse. (The process by which hyphae merge with each other is known as “anastomosis,” which in Greek means “to provide with a mouth.”) If hyphae couldn’t branch, one hypha could never become many. If hyphae couldn’t fuse with one another, they would not be able to grow into complex networks. However, before they fuse, hyphae must find other hyphae, which they do by attracting one another, a phenomenon known as “homing.

Reintroducing history into evolutionary thinking has already begun at other biological scales. The cell, once an emblem of replicable units, turns out to be the historical product of symbiosis among free- living bacteria. Even DNA turns out to have more history in its amino- acid sequences than once thought. Human DNA is part virus; viral encoun- ters mark historical moments in making us human. Genome research has taken up the challenge of identifying encounter in the making of DNA. Population science cannot avoid history for much longer. Fungi are ideal guides. Fungi have always been recalcitrant to the iron cage of self- replication. Like bacteria, some are given to exchanging genes in nonreproductive encounters (“horizontal gene transfer”); many also seem averse to keeping their genetic material sorted out as “individ- uals” and “species,” not to speak of “populations.” When researchers studied the fruiting bodies of what they thought of as a species, the ex- pensive Tibetan “caterpillar fungus,” they found many species entan- gled together. When they looked into the filaments of Armillaria root rot, they found genetic mosaics that confused the identification of an individual. Meanwhile, fungi are famous for their symbiotic attach- ments. Lichen are fungi living together with algae and cyanobacteria. I have been discussing fungal collaborations with plants, but fungi live with animals as well. For example, Macrotermes termites digest their food only through the help of fungi. The termites chew up wood, but they cannot digest it. Instead, they build “fungus gardens” in which the chewed- up wood is digested by Termitomyces fungi, producing edible nutrients. Researcher Scott Turner points out that, while you might say that the termites farm the fungus, you could equally say that the fungus farms the termites. Termitomyces uses the environment of the termite mound to outcompete other fungi; meanwhile, the fungus regulates the mound, keeping it open, by throwing up mushrooms annually, cre- ating a colony- saving disturbance in termite mound- building.

Picture the furry tendrils of fungal growth that must have been entwining his taint and scrotuscus. Close your eyes and imagine you smell the moist, spidery growths that might have been carpeting his armpits.

Writing the fungus into the story encourages us to adopt a more fungal point of view.

Fungal networks provide highways for bacteria to migrate around the obstacle course of the soil.

plant communication through fungal networks is one of the most compelling aspects of mycorrhizal behavior.

Ecosystems are complex, and there is no single fungal solution that will work in all sites and conditions.

She argues that the field of neuroscience can provide tools to better understand how complex behaviors arise in ecosystems linked by fungal networks.

Brains, like fungal networks, reconfigure themselves—or “adaptively rewire”—in response to new situations.

It should also be mentioned that since 2006, a relatively mysterious fungal disease known as White-nose syndrome has killed more than six million bats in North America. The cause and cure is currently being researched, but I believe as of now the decimated populations remain a sad mystery. Here’s to hoping these little dudes prosper in the face of terrible times.

It has been well established that trees talk to each other through underground chains of fungus called Common Mycorrhizal Networks (CMNs). Affectionately called the Wood Wide Web, these networks allow networks of trees to locally communicate and organize the transfer of water, carbon, nitrogen, local gossip, and political pamphlets. Previous research suggested that these fungal networks only operated at a community level. Nutrient-transfer-back translation has shown this assumption is no longer valid. In the woods of Germany, England, Wyoming, and many more locations, accelerationist, international communist propaganda has been discovered in Douglas Firs, and a growing prevalence has been seen in Birch populations. This paper will discuss the methodology, results, and dangerous consequences of the dictatorship of a central, democratically elected, tree-based anarcho-communist syndicate of Fir collectives in your backyard and how the international communist organization has spread its radical message to the world’s forests.

The overwhelming majority of fungal species release spores without producing mushrooms at all.

Convergence is ubiquitous and not limited just to the external appearance or morphology of animals. It is also widely observed and documented in animal behavior and in plants, fungi, and even bacteria. Let’s start with behavior. What do you think these four species—a cobra, a stickleback fish, an octopus, and a spider—share? There is no convergence in body form here, unlike the Caribbean anoles. But a behavior has converged among them that has led to the success of each of their species: the females of the species guard their eggs. One of the best examples of convergent behavior is observed in humans and—hold your breath—ants! And I have witnessed this convergence with my own eyes. When I was on a family vacation in the stunningly beautiful Peruvian Amazon, I stumbled upon the tiny creatures that had beaten our human ancestors to the discovery of agriculture by many millions of years: the leafcutter ants. I had waited years to witness the miracle, and there it was in its full linear glory. A long single column of thousands of large green leaves appeared to be miraculously moving in perfect synchrony of their own volition on the forest floor. Each large leaf was being carried by a single tiny ant, who purposefully disappeared underground to pass on the booty to her specialist sisters. These ants chew the leaves to grow a fungus garden used for food for the entire colony. Not unlike human farmers, these ants produce fertilizers (amino acids and enzymes) to aid the fungal growth, remove contaminants that can hinder the agricultural output, are highly selective in what they grow, and continuously tend to their enormous gardens.8

Then where does Monotropa’s carbon come from? Mycorrhizal fungi obtain all their carbon from green plants. This means that the carbon that powers the life of Monotropa—the bulk of the stuff from which they are made—must ultimately come from other plants via a shared mycorrhizal network: If carbon didn’t flow from a green plant to Monotropa through shared fungal connections, Monotropa couldn’t survive.

grass from salty coastal soils, grow it without its fungal endophytes, and it won’t be able to survive in its natural salty habitat.

Not only was the abundance of mycorrhizal fungi higher in organically managed fields but the fungal communities were also far more complex: Twenty-seven species of fungi were identified as highly connected, or “keystone species,” compared with none in the conventionally managed fields.

they also warn each other using chemical signals sent through the fungal networks around their root tips,

No being on our planet can maintain a centuries-long fast, not even the remains of a tree, and certainly not a stump that has had to survive on its own. It was clear that something else was happening with this stump. It must be getting assistance from neighboring trees, specifically from their roots. Scientists investigating similar situations have discovered that assistance may either be delivered remotely by fungal networks around the root tips—which facilitate nutrient exchange between trees1—or the roots themselves may be interconnected.2 In the case of the stump I had stumbled upon, I couldn’t find out what was going on, because I didn’t want to injure the old stump by digging around it, but one thing was clear: the surrounding beeches were pumping sugar to the stump to keep it alive.

You find twice the amount of life-giving nitrogen and phosphorus in plants that cooperate with fungal partners than in plants that tap the soil with their roots alone.

Dr. Suzanne Simard, who helped discover maternal instincts in trees, describes mother trees as dominant trees widely linked to other trees in the forest through their fungal–root connections. These trees pass their legacy on to the next generation and exert their influence in the upbringing of the youngsters.18

Here’s a little outsider information, and you can wait for it to be confirmed. A forest knows things. They wire themselves up underground. There are brains down there, ones our own brains aren’t shaped to see. Root plasticity, solving problems and making decisions. Fungal synapses. What else do you want to call it? Link enough trees together, and a forest grows aware.

Despite all this, I am not anxious when I think about the future of our forests. For on large continents (and the Eurasian continent is the largest one of all) species have to come to grips with new arrivals all the time. Migrating birds bring small animals, fungal spores, or the seeds of new species of trees tucked in their feathers, or these organisms are blown in by turbulent storms. A five-hundred-year-old tree has surely had a few surprises in its life. And thanks to the great genetic diversity in a single species of tree, there is always a sufficient number of individuals that can rise to a new challenge.

In a groundbreaking study published in the journal Nature, Dr Suzanne Simard of the University of British Columbia discovered communication networks in stands of Douglas firs, which she dubbed the ‘Wood Wide Web’, suggesting the connectivity of trees. This research has been popularized by German naturalist Peter Wohlleben in his bestseller The Hidden Life of Trees. He describes how oaks and beeches share information using microscopic fungal filaments, comparing these to fibre-optic Internet cables. ‘One teaspoon of forest soil contains many miles of these “hyphae”. Over centuries a single fungus can cover many square kilometres and network an entire forest. The fungal connections transmit signals from one tree to the next, helping them exchange news about insects, drought, and other dangers.

Before it dies, a Douglas-fir, half a millennium old, will send its storehouse of chemicals back down into its roots and out through its fungal partners, donating its riches to the community pool in a last will and testament.

those self-grafted knots, the two trees join their vascular systems together and become one. Networked together underground by countless thousands of miles of living fungal threads, her trees feed and heal each other, keep their young and sick alive, pool their resources and metabolites into community chests. . . . It will take years for the picture to emerge.

There are around 200 species of leaf-cutter ants that do this, and it’s been part of their existence for more than twenty million years. They are obligate fungal cultivars, meaning they fully depend on this activity, just as we do on farmed food. The dependence is mutual too: the fungus grows filaments called gongylidia, which are packed with nutritious carbohydrates and lipids, so that the ants can harvest them more easily to feed to the queens and larvae. Gongylidia don’t exist outside of fungal-ant agriculture. There’s a further outrageous layer to this symbiosis. The leaf beds are prone to infection by another fungus, which the ants weed manually (actually, with their mandibles). But they also carry Pseudonocardia bacteria on their bodies and in specialised endocrine glands. These bacteria produce an antibiotic which attacks the fungal infections. This is an astonishing description of mutualism on many levels: an animal farming a fungus, using bacteria as a pesticide, each dependent on the others.

But the real headline is that I have a fungal infection—Psilocybe cubensis, I overhear one of the doctors say. Mushrooms are growing in my blood.

The rootlets branched like a small tree and their surface was covered with a filmy layer which appeared fresh and sticky. It was these delicate structures I wanted to examine. From these roots, a fungal network laced out into the soil and around the roots of nearby trees. Without this fungal web my tree would not exist. Without similar fungal webs no plant would exist anywhere. All life on land, including my own, depended on these networks. I tugged lightly on my root and felt the ground move.

Many of the most dramatic events on Earth have been – and continue to be – a result of fungal activity. Plants only made it out of the water around 500 million years ago because of their collaboration with fungi, which served as their root systems for tens of million years until plants could evolve their own. Today, more than 90 per cent of plants depend on these ‘mycorrhizal’ fungi. This ancient association gave rise to all recognisable life on land, the future of which depends on the continued ability of plants and fungi to form healthy relationships.

Radical fungal technologies can help us respond to some of the many problems that arise from ongoing environmental devastation. Antiviral compounds produced by fungal mycelium reduce colony collapse disorder in honeybees. Voracious fungal appetites can be deployed to break down pollutants, such as crude oil from oil spills, in a process known as mycoremediation. In mycofiltration, contaminated water is passed through mats of mycelium, which filter out heavy metals and break down toxins. In mycofabrication, building materials and textiles are grown out of mycelium and replace plastics and leather in many applications.

Our eyes can distinguish several million colours, our ears can distinguish half a million tones, but our noses can distinguish well over a trillion different odours. Humans can detect virtually all volatile chemicals ever tested. Smells feature in our choice of sexual partners and in our ability to detect fear, anxiety or aggression in others. Human noses can detect some compounds at as low a concentration as 34,000 molecules in one square centimetre, the equivalent of a single drop of water in 20,000 Olympic swimming pools. For an animal to experience a smell, a molecule must land on their olfactory epithelium. In humans, this is a membrane up and behind the nose. The molecule binds to a receptor, and nerves fire. The brain gets involved as chemicals are identified or trigger thoughts and emotional responses. Fungi are equipped with different kinds of bodies. They don’t have noses or brains. Instead, their entire surface behaves like an olfactory epithelium. A mycelial network is one large chemically sensitive membrane: a molecule can bind to a receptor anywhere on its surface and trigger a signalling cascade that alters fungal behaviour. Fungi live their lives bathed in a rich field of chemical information. Truffle fungi use chemicals to communicate to animals their readiness to be eaten; they also use chemicals to communicate with plants, animals, other fungi – and themselves. Through smell, we can participate in the molecular discourse fungi use to organise much of their existence.

Humans wear perfumes produced by other organisms, and it is not uncommon for fungal aromas to be incorporated into our own sexual rituals. Agarwood, or oudh, is a fungal infection of Aquilaria trees found in India and south-east Asia and one of the most valuable raw materials in the world. It is used to make a scent – dank nuts, dark honey, rich wood – and has been coveted at least since the time of the ancient Greek physician Dioscorides. The best oudh is worth more, gram for gram, than gold or platinum – as much as $100,000 per kilogram – and the destructive harvest of Aquilaria trees has driven them to near extinction in the wild.

REDWOODS The first time I entered a forest I saw the trees, of course, huddled together in rings, thin veils of mist between their branches, some dead but still standing, or fallen thigh bones on the desiccated floor, but I also saw the great buttery platters of fungus climbing like stepping stones up their shaggy trunks: tzadee, tzadee, tzadee, each a different size: small to large or large to small, as if some rogue architect had been cocky enough to install them on the stunned trees’ northern sides, leading up to the balcony of their one ton boughs. I was here to investigate my place among them, these giants, 3000 years old, still here, living in my lifetime. I should have felt small, a mere human—petty in my clumsy boots, burrs in my socks, while these trees held a glossary of stars in their crowns, their heads up there in the croissant-shaped clouds, the wisdom of the ages flowing up through from root to branchlet— though rather I felt large inside my life, the sum of Jung’s archetypes: the self, the shadow, the anima, the persona of my personhood fully recognized and finally accepted, the nugget of my being, my shadow of plush light. I felt like I was climbing up those fungal discs toward something endless, beyond my birth and death, into my here-ness and now-ness, the scent and silence overwhelming me, seeping back into my pores. You had to have been there to know such joy, fear intermingled, my limbs tingling: ancient, mute.
