Mysterious Mushroom in Yunnan
In Yunnan Province, China, doctors see hundreds of patients each year reporting a strange symptom: visions of tiny, elf-like figures moving around their homes. These miniature beings appear under doors, crawl on walls, and cling to furniture.
Researchers have traced these unusual hallucinations to Lanmaoa asiatica, a local mushroom. It grows near pine trees and is popular for its savory, umami flavor. People eat it at home, in restaurants, and in markets during peak season from June to August.
The Importance of Cooking
Colin Domnauer, a doctoral candidate studying this species, said, “It seems like very common knowledge in the culture there.”
A Rare Mystery Outside China
Outside Yunnan, L. asiatica remains largely unknown. Giuliana Furci, founder of the Fungi Foundation, explained that many people had tried to find this psychedelic mushroom, but its existence remained elusive until recently.
Domnauer is studying L. asiatica to understand the compound responsible for these unusual hallucinations and what it can teach us about the human brain.
Historical Accounts
Reports of L. asiatica date back decades. In 1991, researchers from the Chinese Academy of Sciences described cases where people saw “lilliputian hallucinations,” tiny human or fantasy figures, after eating the mushroom.
Similar experiences were documented in the 1960s in Papua New Guinea. Researchers Gordon Wasson and Roger Heim encountered stories of locals going “insane” after eating a mushroom. At the time, the phenomenon was dismissed as a cultural tale.
Why Scientists Are Curious
The consistent reports of hallucinatory visions across different regions and cultures make L. asiatica unique.
