Fungi Related Quotes

Another thing cooking is, or can be, is a way to honor the things we're eating, the animals and plants and fungi that have been sacrificed to gratify our needs and desires, as well as the places and the people that produced them. Cooks have their ways of saying grace too... Cooking something thoughtfully is a way to celebrate both that species and our relation to it.

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

Likewise, though words for things being done, such as count and jump, are usually verbs, verbs can be other things, like mental states (know, like), possession (own, have), and abstract relations among ideas (falsify, prove). Conversely, a single concept, like “being interested,” can be expressed by different parts of speech: her interest in fungi [noun] Fungi are starting to interest her more and more. [verb] She seems interested in fungi. Fungi seem interesting to her. [adjective] Interestingly, the fungi grew an inch in an hour. [adverb]

Entomophthora fungus carries around a type of virus that infects insects, not fungi. The lead author of the study reported it to be “one of the whackiest discoveries” of his time in science. What’s whacky is the implication: that the fungus uses the virus to manipulate the mind of insects. It’s still a hypothesis, but it’s plausible. A number of related viruses specialize in modifying insect behavior. One such virus is injected by parasitic wasps into ladybirds, which tremble, remain rooted to the spot, and become guardians for the wasp’s eggs. Another similar virus makes honeybees more aggressive. By harnessing a mind-manipulating virus, the fungus wouldn’t have to evolve the ability to modify the mind of its insect host.

A few hundred million years later, some of these eukaryotes developed a novel adaptation: they stayed together after cell division to form multicellular organisms in which every cell had exactly the same genes. These are the three-boat septuplets in my example. Once again, competition is suppressed (because each cell can only reproduce if the organism reproduces, via its sperm or egg cells). A group of cells becomes an individual, able to divide labor among the cells (which specialize into limbs and organs). A powerful new kind of vehicle appears, and in a short span of time the world is covered with plants, animals, and fungi.37 It’s another major transition. Major transitions are rare. The biologists John Maynard Smith and Eörs Szathmáry count just eight clear examples over the last 4 billion years (the last of which is human societies).38 But these transitions are among the most important events in biological history, and they are examples of multilevel selection at work. It’s the same story over and over again: Whenever a way is found to suppress free riding so that individual units can cooperate, work as a team, and divide labor, selection at the lower level becomes less important, selection at the higher level becomes more powerful, and that higher-level selection favors the most cohesive superorganisms.39 (A superorganism is an organism made out of smaller organisms.) As these superorganisms proliferate, they begin to compete with each other, and to evolve for greater success in that competition. This competition among superorganisms is one form of group selection.40 There is variation among the groups, and the fittest groups pass on their traits to future generations of groups. Major transitions may be rare, but when they happen, the Earth often changes.41 Just look at what happened more than 100 million years ago when some wasps developed the trick of dividing labor between a queen (who lays all the eggs) and several kinds of workers who maintain the nest and bring back food to share. This trick was discovered by the early hymenoptera (members of the order that includes wasps, which gave rise to bees and ants) and it was discovered independently several dozen other times (by the ancestors of termites, naked mole rats, and some species of shrimp, aphids, beetles, and spiders).42 In each case, the free rider problem was surmounted and selfish genes began to craft relatively selfless group members who together constituted a supremely selfish group.

In fact it seems hardly a stretch to ask whether a plant is itself without fungi. Some evidence suggests that plants-which initially came on to the evolutionary scene as amorphous greenish blobs of algae-developed their first leggy forms precisely to house beneficial fungi. "What we call 'plants' are in fact fungi that have evolved to farm algae, and algae that have evolved to farm fungi," Sheldrake argues. By the time the first plant roots appeared, the plants had already been associating with fungi for fifty million years. By some scholars' accounts, roots are literally the product of fungal influence, made to stitch plants and fungi into relation.

Mushrooms use a catapult powered by the acceleration of a tiny droplet of fluid over the spore surface to launch spores from their gills; a relative of mushrooms called the artillery fungus employs a snap-buckling device that resembles a miniature toilet plunger to propel a spore-filled capsule into the air, and cup fungi and other ascomycetes use microscopic squirt guns to blast their spores skyward. Most

How? Next time you’re in a forest, dig into the duff, and you’re bound to find white, cobwebby threads attached to roots. These are the underground parts of special fungi that deliver phosphorus to trees in return for carbon. Textbooks once described the exchange as exclusive, one tree to one fungus, until the data begged to differ. Simard’s work was among the first to prove that fungi branch out from the roots of one tree to connect dozens of trees and shrubs and herbs—not only relatives but entirely different species. [This “wood-wide web” is an underground Internet through which water, carbon, nitrogen, phosphorus, and even defense compounds are exchanged.] When a pest troubles one tree, its alarm chemicals travel via fungi to the other members of the network, giving them time to beef up their defenses. Thanks to researchers like Simard, foresters are now encouraged to leave birch and large hub trees in the forest to give seedlings a fast connection to the network.

With the web uncovered, the intricacies of the belowground alliance still remained a mystery to me, until I started my doctoral research in 1992. Paper birches, with their lush leaves and gossamer bark, seemed to be feeding the soil and helping their coniferous neighbors. But how? In pulling back the forest floor using microscopic and genetic tools, I discovered that the vast belowground mycelial network was a bustling community of mycorrhizal fungal species. These fungi are mutualistic. They connect the trees with the soil in a market exchange of carbon and nutrients and link the roots of paper birches and Douglas firs in a busy, cooperative Internet. When the interwoven birches and firs were spiked with stable and radioactive isotopes, I could see, using mass spectrometers and scintillation counters, carbon being transmitted back and forth between the trees, like neurotransmitters firing in our own neural networks. The trees were communicating through the web! I was staggered to discover that Douglas firs were receiving more photosynthetic carbon from paper birches than they were transmitting, especially when the firs were in the shade of their leafy neighbors. This helped explain the synergy of the pair’s relationship. The birches, it turns out, were spurring the growth of the firs, like carers in human social networks. Looking further, we discovered that the exchange between the two tree species was dynamic: each took different turns as “mother,” depending on the season. And so, they forged their duality into a oneness, making a forest. This discovery was published by Nature in 1997 and called the “wood wide web.” The research has continued unabated ever since, undertaken by students, postdoctoral researchers, and other scientists, with a myriad of discoveries about belowground communication among trees. We have used new scientific tools, as they are invented, along with our curiosity and dreams, to peer into the dark world of the soil and illuminate the social network of trees. The wood wide web has been mapped, traced, monitored, and coaxed to reveal the beautiful structures and finely adapted languages of the forest network. We have learned that mother trees recognize and talk with their kin, shaping future generations. In addition, injured trees pass their legacies on to their neighbors, affecting gene regulation, defense chemistry, and resilience in the forest community. These discoveries have transformed our understanding of trees from competitive crusaders of the self to members of a connected, relating, communicating system. Ours is not the only lab making these discoveries—there is a burst of careful scientific research occurring worldwide that is uncovering all manner of ways that trees communicate with each other above and below ground.

Spribille told me about a paper called “Queer theory for lichens.” (“It comes up as the first thing in Google when you enter ‘queer’ and ‘lichen.’ ”) Its author argues that lichens are queer beings that present ways for humans to think beyond a rigid binary framework: The identity of lichens is a question rather than an answer known in advance. In turn, Spribille has found queer theory a helpful framework to apply to lichens. “The human binary view has made it difficult to ask questions that aren’t binary,” he explained. “Our strictures about sexuality make it difficult to ask questions about sexuality, and so on. We ask questions from the perspective of our cultural context. And this makes it extremely difficult to ask questions about complex symbioses like lichens because we think of ourselves as autonomous individuals and so find it hard to relate.

Creatures with bodies—animals, plants, and fungi—are relative newcomers to the planet, and they are all composed of cells derived from the merger of different individuals.
