Stamets’s ideas and theories have turned out to be far more durable, and practicable, than I ever would have guessed. This was the other reason I became eager to spend some time with Stamets: I was curious to find out how his own experience with psilocybin had colored his thinking and lifework. Yet I wasn’t at all certain he would be willing to talk on the record about psilocybin, much less take me ’shroom hunting, now that he had a successful business, had eight or nine patents to his name, and was collaborating with institutions like DARPA and NIH and the Lawrence Livermore National Laboratory. In the more recent interviews and lectures I could find online, he seldom talked about psilocybin and often omitted mention of the field guide from his list of publications. What’s more, he had just received prestigious honors from the Mycological Society of America and the American Association for the Advancement of Science (AAAS). Paul Stamets, it seemed, had gone legit. Bad timing for me.

THANKFULLY, I WAS WRONG. When I reached Stamets at his home in Kamilche, Washington, and told him what I was up to, he couldn’t have been more forthcoming or cooperative. We talked for a long time about psilocybin mushrooms, and it soon became clear they remained a subject of keen interest to him. He knew all about the work going on at Hopkins—in fact had consulted with the Hopkins team when they were first looking for a source of psilocybin. My impression was that the revival of legitimate university research had made Stamets more comfortable reopening this particular chapter in his life. He mentioned he was in the process of updating the 1996 psilocybin field guide. The only discordant note in the conversation came when I casually dropped the slang expression for psilocybin when asking him about going hunting for ’shrooms.
“I really, really hate that word,” he said, almost gravely, adopting the tone of a parent upbraiding a potty-mouthed child.
The word never crossed my lips again.
By the end of the call, Stamets had invited me up to his place in Washington State, on the Little Skookum Inlet at the base of the Olympic Peninsula. I asked him, gingerly, if I could come at a time when the Psilocybes were fruiting. “Most of them have already come and gone,” he said. “But if you come right after Thanksgiving, and the weather’s right, I can take you to the only place in the world where Psilocybe azurescens has been consistently found, at the mouth of the Columbia River.” He mentioned the name of the park where he had found them in the past and told me to book a yurt there, adding, “Probably best not to use my name.”

IN THE WEEKS BEFORE my trip to Washington State, I pored over Stamets’s field guide, hoping to prepare myself for the hunt. It seems there are more than two hundred species of Psilocybe, distributed all over the world; it’s not clear whether that’s always been the case, or if the mushrooms have followed in the footsteps of the animals who have taken such a keen interest in them. (Humans have been using psilocybin mushrooms sacramentally for at least seven thousand years, according to Stamets. But animals sometimes ingest them too, for reasons that remain obscure.)
Psilocybes are saprophytes, living off dead plant matter and dung. They are denizens of disturbed land, popping up most often in the habitats created by ecological catastrophe, such as landslides, floods, storms, and volcanoes. They also prosper in the ecological catastrophes caused by our species: clear-cut forests, road cuts, the wakes of bulldozers, and agriculture. (Several species live in and fruit from the manure of ruminants.) Curiously, or perhaps not so curiously, the most potent species occur less often in the wild than in cities and towns; their predilection for habitats disturbed by us has allowed them to travel widely, “following streams of debris,” including our own. In recent years, the practice of mulching with wood chips has vastly expanded the range of a handful of potent Psilocybes once confined to the Pacific Northwest. They now thrive in all those places we humans now “landscape”: suburban gardens, nurseries, city parks, churchyards, highway rest stops, prisons, college campuses, even, as Stamets likes to point out, on the grounds of courthouses and police stations. “Psilocybe mushrooms and civilization continue to co-evolve,” Stamets writes.
So you would think these mushrooms would be fairly easy to find. In fact after I published an article about psilocybin research, I was informed by a student that after the December rains Psilocybes can be found on the Berkeley campus, where I teach. “Look in the wood chips,” he advised. Yet as soon as I began studying the photographs in Stamets’s field guide, I began to despair of ever identifying any mushroom as a member of the genus, much less learning how to distinguish one species of Psilocybe from another.
To judge from the pictures, the genus is just a big bunch of little brown mushrooms, most of them utterly nondescript. By comparison, the edible species with which I was familiar were as distinct as tulips are from roses, poodles from Great Danes. Yes, all the Psilocybes have gills, but that isn’t much help, because thousands of other mushrooms have gills, too. After that, you’re trying to sort out a bewildering array of characteristics, not all of which are shared by the class. Some Psilocybes have a little nipple-like knob or protrusion on top—it’s called an umbo, I learned; others don’t. Some were “viscid”—slippery or slimy when wet, giving them a shiny appearance. Others were dull and matte gray; some, like azurescens, were a milky caramel color. Many but not all Psilocybes sport a “pellicle”—a condom-like layer of gelatinous material covering the cap that can be peeled off. My fungal vocabulary might be expanding, but my confidence was rapidly collapsing, much like the mushroom that, in the course of a single day, decomposes into an inky puddle.
By the time I got to chapter four, “The Dangers of Mistaken Identification,” I was ready to throw in the towel. “Mistakes in mushroom identification can be lethal,” Stamets begins, before displaying a photograph in which a Psilocybe stuntzii is seen growing cheek by jowl with a trio of indistinguishable Galerina autumnalis, an unremarkable little mushroom that, when eaten, “can result in an agonizing death.”
But while Stamets urges extreme circumspection in amateurs hoping to identify Psilocybes, he also equips the mushroom hunter who hasn’t been completely discouraged with something he calls “The Stametsian Rule”: a three-pronged test that, he (sort of) assures us, can head off death and disaster.
“How do I know if a mushroom is a psilocybin producing species or not?”
“If a gilled mushroom has purplish brown to black spores, and the flesh bruises bluish, the mushroom in question is very likely a psilocybin-producing species.” This is definitely a big help, though I wouldn’t mind something more categorical than “very likely.” He then offers a sobering caveat. “I know of no exceptions to this rule,” he adds, “but that does not mean there are none!”
After committing to memory the Stametsian Rule, I began picking promising-looking gilled LBMs—in my neighbors’ yards, on my walk to work, in the parking lot of the bank—and then roughing them up a bit to see if they would turn black and blue. The blue pigment is in fact evidence of oxidized psilocin, one of the two main psychoactive compounds in a Psilocybe. (The other is psilocybin, which breaks down into psilocin in the body.) To determine if the mushroom in question had purplish-brown or black spores, I began making spore prints. This involves cutting the cap off a mushroom and placing it, gill side down, on a piece of white paper. (Or black paper if you have reason to believe the mushroom has white spores.) Within hours, the mushroom cap releases its microscopic spores, which will form a pretty, shadowy pattern on the paper (reminiscent of a lipstick kiss) that you can then try to decide is purplish brown or black—or rust colored, in which case you might have a deadly Galerina on your hands.
Certain things are perhaps best learned in person, rather than from a book. I decided I should probably wait before making any irreversible decisions until I had spent some time in the company of my mycological Virgil.

AT THE TIME OF MY VISIT, Paul Stamets lived with his partner, Dusty Yao, and their two big dogs, Plato and Sophie, in a sprawling new house on the Little Skookum Inlet that is constructed inside and out of a small forest’s worth of the most gorgeous clear Douglas fir and cedar. Like many species of fungi, Stamets has a passionate attachment to trees and wood. I arrived on a Friday; our reservation at the campsite wasn’t until Sunday night, so we had the better part of the weekend to talk Psilocybes, eat (other kinds of) mushrooms, tour the Fungi Perfecti facilities, and ramble the surrounding woods and shoreline with the dogs before driving south to the Oregon border Sunday morning to hunt azzies.
This was the house that mushrooms built, Stamets explained, launching into its story before I had a chance to unpack my bag. It replaced a rickety old farmhouse on the site that, when Stamets moved in, was slowly succumbing to an infestation of carpenter ants. Stamets set about devising a mycological solution to the problem. He knew precisely which species of Cordyceps could wipe out the ant colony, but so did the ants: they scrupulously inspect every returning member for Cordyceps spores and promptly chew off the head of any ant bearing spores, dumping the body far away from the colony. Stamets outwitted the ants’ defense by breeding a mutant Cordyceps-like fungus that postponed sporulation. He put some of its mycelium in his daughter’s dollhouse bowl, left that on the floor of the kitchen, and during the night watched as a parade of ants carried the mycelium into the nest—having mistaken it for a safe food source. When the fungus eventually sporulated, it was already deep inside the colony and the ants were done for: the Cordyceps colonized their bodies and sent fruiting bodies bursting forth from their heads. It was too late to save the farmhouse, but with the proceeds from the sale of his patent on the fungus Stamets was able to erect this far grander monument to mycological ingenuity.
The house was spacious and comfortable; I had a whole upstairs wing of bedrooms to myself. The living room, where we spent most of a rainy December weekend, had a soaring cathedral ceiling, a big wood-burning fireplace, and, looming over the room from across the way, a seven-and-a-half-foot-tall skeleton of a cave bear. A painting of Albert Hofmann hangs over the fireplace. Overhead, beneath the peak, is a massive round stained glass depicting “The Universality of the Mycelial Archetype”—an intricate tracery of blue lines on a night sky, the lines representing at once mycelium, roots, neurons, the Internet, and dark matter.
Displayed on the walls heading upstairs from the living room are framed artworks, photographs, and keepsakes, including a diploma signifying the successful completion of one of the Merry Pranksters’ Acid Tests, signed by Ken Kesey and Neal Cassady. There are several photographs of Dusty posing in old-growth forests with impressive specimens of fungi and a colorfully grotesque print by Alex Grey, the dean of American psychedelic artists. The print is Grey’s interpretation of the so-called stoned ape theory, depicting an early, electrified-looking hominid clutching a Psilocybe while a cyclone of abstractions flies out of its mouth and forehead. The only reason I could make any sense of the image at all was that a few days earlier I had received an e-mail from Stamets referring to the theory in question: “I want to discuss the high likelihood that the Stoned Ape Theory, first presented by Roland Fischer and then popularized/restated by Terence McKenna, is probably true—[ingestion of psilocybin] causing a rapid development of the hominid brain for analytical thinking and societal bonding. Did you know that 23 primates (including humans) consume mushrooms and know how to distinguish ‘good’ from ‘bad’?”
I did not.
But the brief, elliptical e-mail nicely prefigured the tenor of my weekend with Stamets as I struggled to absorb a torrent of mycological fact and speculation that, like a rushing river, is impossible to ford without being knocked sideways. The sheer brilliance of Stamets’s mushroom’s-eye view of the world can be dazzling, but after a while it can also make you feel claustrophobic, as only the true monomaniac or autodidact—and Stamets is both—can do. Everything is connected is ever the subtext with such people; in this case what connects everything you could possibly think of just happens to be fungal mycelia.
I was curious to find out how Stamets came by his mycocentric worldview and what role psilocybin mushrooms, in particular, might have contributed to it. Stamets grew up in an Ohio town outside Youngstown called Columbiana, the youngest of five children. His father’s engineering company went belly-up when Paul was a boy, the family “going from riches to rags pretty quickly.” Dad began to drink heavily, and Paul began looking up to his older brother John as a role model.
Five years his senior, John was an aspiring scientist—he would receive a scholarship to study neurophysiology—who kept “an exquisite laboratory in the basement,” a realm that was Paul’s idea of heaven, but to which John seldom granted his little brother admittance. “I thought all houses had laboratories, so whenever I went over to a friend’s house, I would ask where the laboratory was. I didn’t understand why they would always point me to the bathroom instead—the lavatory.” Winning John’s approval became a motive force in Paul’s life, which perhaps explains the value Stamets places on mainstream scientific recognition of work. John had died, of a heart attack, six months before my visit and, as it happened, on the same day Paul received word of his AAAS honor. His death was a loss from which Paul hadn’t yet recovered.
When Paul was fourteen, John told him about magic mushrooms, and when he went off to Yale, John left behind a book, Altered States of Consciousness, that made a tremendous impression on Paul. Edited by Charles T. Tart, a psychologist, the book is a doorstop of an anthology of scholarly writings about non-ordinary mental states, covering the spectrum from dreaming and hypnosis to meditation and psychedelics. But the reason the book made such a lasting impression on Stamets had less to do with its contents, provocative as these were, than with the reaction the book elicited in certain adults.
“My friend Ryan Snyder wanted to borrow it. His parents were really conservative. A week later, when I told him I wanted it back, he stalls and delays. Another week goes by, I ask him again, and he finally confesses what happened. ‘My parents found it and they burned it.’
“They burned my book?!? That was a pivotal moment for me. I saw the Snyders as the enemy, trying to suppress the exploration of consciousness. But if this was such powerful information that they felt compelled to destroy it, then this was powerful information I now had to have. So I owe them a debt of gratitude.”
Stamets went off to Kenyon College, where, as a freshman, he had “a profound psychedelic experience” that set his course in life. As long as he could remember, Stamets had been stymied by a debilitating stutter. “This was a huge issue for me. I was always looking down at the ground because I was afraid people would try to speak to me. In fact, one of the reasons I got so good at finding mushrooms was because I was always looking down.”
One spring afternoon toward the end of his freshman year, walking alone along the wooded ridgeline above campus, Stamets ate a whole bag of mushrooms, perhaps ten grams, thinking that was a proper dose. (Four grams is a lot.) As the psilocybin was coming on, Stamets spied a particularly beautiful oak tree and decided he would climb it. “As I’m climbing the tree, I’m literally getting higher as I’m climbing higher.” Just then the sky begins to darken, and a thunderstorm lights up the horizon. The wind surges as the storm approaches, and the tree begins to sway.
“I’m getting vertigo but I can’t climb down, I’m too high, so I just wrapped my arms around the tree and held on, hugging it tightly. The tree became the axis mundi, rooting me to the earth. ‘This is the tree of life,’ I thought; it was expanding into the sky and connecting me to the universe. And then it hits me: I’m going to be struck by lightning! Every few seconds there’s another strike, here, then there, all around me. On the verge of enlightenment, I’m going to be electrocuted. This is my destiny! The whole time, I’m being washed by warm rains. I am crying now, th
ere is liquid everywhere, but I also feel one with the universe.
“And then I say to myself, what are my issues if I survive this? Paul, I said, you’re not stupid, but stuttering is holding you back. You can’t look women in the eyes. What should I do? Stop stuttering now—that became my mantra. Stop stuttering now, I said it over and over and over.
“The storm eventually passed. I climbed down from the tree and walked back to my room and went to sleep. That was the most important experience of my life to that point, and here’s why: The next morning, I’m walking down the sidewalk, and here comes this girl I was attracted to. She’s way beyond my reach. She’s walking toward me, and she says, ‘Good morning, Paul. How are you?’ I look at her and say, ‘I’m doing great.’ I wasn’t stuttering! And I have hardly ever stuttered since.
“And that’s when I realized I wanted to look into these mushrooms.”

IN A REMARKABLY SHORT SPAN of time, Stamets made himself into one of the country’s leading experts on the genus Psilocybe. In 1978, at the age of twenty-three, he published his first book, Psilocybe Mushrooms and Their Allies—their allies understood to be us, the animal that had done the most to spread their genes and, as Stamets now saw as his calling, their planetary gospel.
Stamets got his mycological education not at Kenyon, which he left after one year, but at the Evergreen State College, which in the mid-1970s was a new experimental college in Olympia, Washington, where students could design their own course of independent study. A young professor named Michael Beug, who had a degree in environmental chemistry, agreed to take under his wing Stamets and two other equally promising mycologically obsessed students: Jeremy Bigwood and Jonathan Ott. Beug was not himself a mycologist by training, but the four of them mastered the subject together, with the help of an electron microscope and a DEA license that Beug had somehow secured. Thus armed, the four trained their attention on a genus that the rest of the field generally chose to pass over in uncomfortable silence.
