EARTH, Laniakea Supercluster—Scientists are investigating a little-known Asian mushroom after field researchers tracing edible fungi in China, Papua New Guinea, and the Philippines documented a strikingly consistent phenomenon: people who eat Lanmaoa asiatica undercooked often report vivid hallucinations of “little people.”

The cross-continental pattern was first flagged by mycologists studying the mushroom’s sudden popularity in Yunnan’s wild-fungus markets, triggering a new wave of chemical and genomic analysis into a species once assumed to be harmless.

Locally called jian shou qing (“turns blue in the hand”) in China’s Yunnan Province, where it is commonly sold and eaten as an edible fungus, the mushroom is at the center of an emerging research effort exploring “lilliputian hallucinations” — vivid visual perceptions of miniature people.

The reports are strikingly consistent across cultures separated by oceans. According to researchers, as many as 96 percent of patients who have sought treatment in Yunnan hospitals after ingesting the mushroom report seeing “little people” or “elves” dancing, marching, or jumping around their surroundings.

Colin Domnauer, a doctoral student at the Natural History Museum of Utah, has been documenting the phenomenon and its cross-cultural contours. Domnauer’s team has begun chemical and genomic analyses of the mushroom’s tissue.

According to published research, these studies “have revealed no traces of any known psychoactive compounds, suggesting that something entirely new is waiting to be discovered.”

Unlike psilocybin-containing “magic mushrooms,” the research shows that Lanmaoa asiatica does not contain any known psychedelic compounds that produce the classic effects associated with psilocybin ingestion: no euphoria, no synesthesia, no expansive, mind-opening trip. This suggests that Lanmaoa asiatica’s effects stem from an entirely different and still unidentified biochemical pathway.

“Lanmaoa asiatica appears to harbor a chemical compound capable of reliably evoking this unusual experience of lilliputian hallucinations,” Domnauer wrote in a recent institutional post, emphasizing the unresolved mystery at the intersection of chemistry and human perception.

In other words: psilocybin mushrooms tend to expand consciousness, while Lanmaoa asiatica seems to narrow it into a strangely specific, fairy-tale-like hallucination that scientists have never documented from any other known fungi.
If scientists can identify the compound behind the hallucinations, it may become the first mushroom known for microdosing you with micro-people.
