Lanmaoa asiatica Triggers Unique Lilliputian Hallucinations

Core Discovery: Tiny, Three-Dimensional Figures Appear After Ingestion
A study in *Mycologia* reports that eating the bolete mushroom *Lanmaoa asiatica* reliably induces vivid hallucinations of tiny, three-dimensional people in the external environment. The figures appear 12–24 hours after ingestion and may persist for several days, while users otherwise remain functionally sober.
Background & Culinary Context
Typical ‘magic mushrooms’ contain psilocybin or psilocin. *L. asiatica* grows in southwestern China and the Philippines and is sold in local markets. Four varieties are sold; when undercooked or eaten raw, the mushroom can trigger a psychedelic episode with miniature figures. Anecdotal reports span decades; the species entered scientific literature about ten years ago.
Data & Timeline
*L. asiatica* originates from southwestern China and the Philippines and is sold in four varieties. Scientific recognition began ten years ago. Hallucinations appear 12–24 hours after ingestion and can last days. Researchers have started genome sequencing and mouse testing, narrowing candidate compounds.
Official Statements & Research Outlook
University of Utah postdoc Colin Domnauer notes that no known psychoactive genes have been found in *L. asiatica* and chemical databases have no matches, so the team is using comparative genomics to locate the responsible molecule. Mouse studies have isolated a few candidate substances, but further testing is required to confirm relevance to humans.
Verbatim Quotes
- “Even to this day science doesn’t understand what’s going on in the brain to cause this, or how to treat it, and this mushroom is the only thing that we currently know of to reliably produce this effect,” — Colin Domnauer, University of Utah
- “These aren’t like some vague hallucinations, these are like three-dimensionally-rendered, highly-detailed figures inhabiting your exterior world. And they’re also interacting with objects in the real world — like crawling up chairs and tables or under doorways.” — Colin Domnauer
- “The little people are said to typically like teasing, playing with or harassing the person seeing them,” — Colin Domnauer
- “There weren’t even any known psychoactive compounds, so it seemed like this must be some new hallucinogenic compound waiting to be discovered, because there’s nothing that matches anything in our database.” — Colin Domnauer
On-the-Ground Reports
Consumers in Chinese and Philippine markets report that raw or undercooked *L. asiatica* can induce multi-day trips with miniature figures that tease or harass them. Many continue to eat the mushroom despite the effect.
Conflicting Reports & Knowledge Gaps
Scientific records list no known compound that produces Lilliputian hallucinations. Mouse studies have narrowed a few candidate molecules, but the exact active substance in humans remains unverified. The mushroom’s genome also lacks known psychoactive genes, leaving a gap between observed effects and molecular explanation.
What’s Next: Ongoing Genomic and Pharmacological Work
Domnauer’s team will finish genome sequencing of the Lanmaoa genus, expand mouse testing of candidate compounds, and partner with chemists to isolate the active molecule. Identifying the compound could inform neuropharmacology and guide culinary safety guidelines.
