Lilliputian Lore: The Science and Mystery of
Hallucinogenic Bolete Mushrooms

Decades before psilocybin was known to science, a stranger mushroom was being reported across three unconnected cultures — one that makes you see tiny people. Colin Domnauer traces the mycological, ethnographic, and laboratory investigation of this long-overlooked phenomenon.

“Most people are familiar with psilocybin mushrooms. But what most don’t realize is that decades before psilocybin was known to the world, there were reports of a different kind of psychoactive mushroom — one producing visions of little people across three independent cultures. This course investigates whether that phenomenon has a real chemical basis, and what it might reveal about the human mind.”

Understand why hallucinogenic bolete mushrooms represent a potential third independent origin of psychoactive compounds in the fungal kingdom

Trace the ethnographic record of “mushroom madness” from 1930s Papua New Guinea through modern Yunnan and the northern Philippines

Evaluate the taxonomic challenge of identifying cryptic bolete species and why morphological convergence complicates the science

Understand the clinical pharmacology of Lanmaoa asiatica — including why its effects can persist for one to five days

Follow the field and laboratory methodology used to DNA-verify the species responsible across two independent cultural reports

Assess the current state of fractional analysis and what it means that the psychoactive compound remains unidentified

Marching Visions and Media Frenzies: Modern Reports on a Culinary Mystery

Colin Domnauer recounts how a man in Yunnan lifted a tablecloth to find hundreds of two-centimetre-tall figures marching like soldiers — and how this kind of testimony, documented independently across cultures, forced the question of whether a real chemical compound was involved. The lesson also covers the scale of hospital admissions, the media frenzy triggered when Janet Yellen ate these mushrooms in China, and why the science has lagged so far behind the cultural record.

Colin Domnauer, PhD

Colin Domnauer is a PhD researcher in ethnobiology at the University of Utah, where his work has centered on one of mycology’s most neglected puzzles: the hallucinogenic bolete mushrooms reported across Papua New Guinea, Yunnan, and the northern Philippines. His research spans three continents — collecting specimens in Yunnan mushroom markets, working with local guides in the Philippines, and conducting chemical extractions and mice bioassays in the lab. Through DNA sequencing, he identified Lanmaoa asiatica as the species responsible in two of the three independent cultural reports, providing the first rigorous molecular evidence that this phenomenon has a real biological basis. His work sits at the intersection of fieldwork, phylogenetics, and an unsolved pharmacological mystery.

This course sits at the intersection of the Mycology pathway, the Ethnobotany pathway, and the Psychedelics & Science pathway inside the Living Library — bringing fieldwork, cross-cultural documentation, and laboratory pharmacology together around a phenomenon that has been overlooked for nearly a century.
