Last weekend’s Radical Mycology Convergence was an eye-opener to the mystery and power of the fungus kingdom.

Did you know that fungi called endophytes live within plants, lending structure and resilience to the plant? “If we took away the fungal cells, we would see these scrawny, floppy little trees,” said Maia, one of the organizers.

Or that mycorrhizal fungi help plant roots take in nutrients in exchange for sugars? Trees in a forest benefit from this “silent stewardship role,” said Peter, an organizer and earlier contributor to this blog. He explained that the mycelium channels sugars to baby trees deep under the forest canopy to ensure their survival. Perhaps thinking of the “next seven spore generations.”

Or that only 10 percent of our cells is actually human—the rest bacterial and fungal? “We need to stop thinking of ourselves as singular organisms,” said Willoughby, another organizer. “We are walking ecosystems. We need to appreciate and nurture all these cells within us.”

From microscopic fungi, whose ecological role is often overlooked, to the 2500-acre honey mushroom in Oregon (largest living organism in the world), the message is clear: Fungi offer the human race a model and a hope.

What struck me about the Radical Mycology Convergence was the deep respect for nature in general and fungi in particular. Here is a movement that is not about exploitive, extractive approaches to a “natural resource,” but rather: working with fungi as allies for the betterment of all life. That includes cultivating mushrooms for food sovereignty, medicine, and remediation.

The promise of mycoremediation is great, and Radical Mycology is all about spreading the tools for home cultivation. But as Peter emphasized, we need to be humble in our explorations. We don’t want to just burst onto a contaminated scene and “throw oyster mushrooms at it” without first observing the healing already taking place, organically, through the wisdom of the fungi naturally present.

“Who are we to say we know more than nature does?” he said. The time for presumptive action is over. We must first watch, learn, observe.

I learned so much more, but here’s one last thing: When a mushroom gets ready to reproduce, it sends out spores. A spore germinates into a hypha, a filament. It’s one strand of what eventually, with luck, becomes a mycelial network.

But that hypha is only one cell thick, and needs a partner, a genetic match. It works invisibly, underground. You can’t see it. If it comes together with another hypha, that’s when mycelium begins to branch in all directions through its environment. And finally, when conditions are right, it makes a beautiful fruiting body, a mushroom.

A fitting metaphor for social change work, which is not always visible to the mainstream.

We may feel like we’re laboring in the dark, but when we connect with others—even starting with just one!—the network that results can produce something nourishing and healthy, a powerful gift that seems to show up “overnight.”
