Reggie Harris is an organizer and outspoken critic of the corporate capture of psychedelics. As founder of Oakland Hyphae and co-founder of Hyphae Labs, he pioneered mushroom potency testing as harm reduction, expanding into broader drug testing to keep people safe and informed.
His work spans the globe, from consulting with the largest cultivators in the U.S. and the Netherlands to building farms and labs in Jamaica. Harris also created Hyphae Leaks with Psychedelics Today to call out the issues the industry avoids. Serving on the Board of Decriminalize Nature, he fights to keep psychedelics accessible to the people.
Tomás Garrett is an Analytical Chemist with an MBA, bent on making complex science easier to understand . As the Founder of The Myco Zine and an inaugural member of the Hyphae Team, mushroom science and education has always been the mission.
The Myco Zine is a zine (Mini-Magazine) that features foragers, artisans, cultivators, and educators in the mycology space. With a goal of learning from the mycelium, The Myco Zine has taken a grassroots approach that is turning rhizomorphic!
Numbers Don’t Lie: What Six Years of Psilocybin Testing Has Shown Us
Over the last six years, Hyphae Labs has run the largest independent dataset of psilocybin potency testing, working directly with cultivators, patients, and communities. This talk will unpack what we’ve learned about how wildly potency varies across strains, how testing changes harm reduction, and how the mushroom community is quietly setting higher standards than regulators.
We’ll also look ahead: what the data suggests about dosing, safety, and the future of mushroom science in a world that’s trying to commercialize psychedelics. Expect myth-busting, hard truths, and a glimpse at where the field is headed next.
The Mycological Society of San Francisco has been hosting 1 or 2 Fungus Fairs each year since 1969. Fairs have been held in San Francisco County, Alameda County, San Mateo County, and Marin County. Historical information is available about previous Fungus Fairs:
