The Mushroom That Makes the Brain See Little People

Imagine settling down with a steaming bowl of mushroom soup, and suddenly you are joined by a brigade of tiny people parading across the table! No, your brain hasn’t been quantum-entangled with Gulliver’s Travels — you’ve just met a real fungus that reliably summons lilliputian hallucinations.

The culprit is a bolete mushroom called Lanmaoa asiatica, a woodsy relative of porcini treasured for its umami richness in parts of Asia. In China's Yunnan province, people know to cook it thoroughly before eating -- leave it undercooked, and you might start seeing xiao ren ren, literally "little people." Doctors in local hospitals treat hundreds of such cases each year, with patients reporting pint-sized elves crawling over walls or marching under doors.

What makes this species scientific gold is that these hallucinations are remarkably consistent across different individuals and cultures -- unlike the wildly variable visions from classic psilocybin mushrooms. That means when two people eat it, they don't each see a personal fantasy of neon swirls or melting clocks -- they both see tiny humanoids.

That predictability invites comparison to the curious phenomenon of DMT elves, the small, entity-like beings frequently reported by users of the powerful psychedelic DMT. Despite vastly different chemistry and delivery methods, both experiences point to a curious feature of the human brain. Under certain conditions, it reliably generates tiny social beings, as if perception contains a built-in "miniature character" setting, though some posit the DMT elves may be a form of alien life.

Researchers led by biologist Colin Domnauer are on the trail of the mystery molecule inside L. asiatica that flips neural circuits into this specific "lilliputian" mode. So far, chemical analyses have failed to find any known hallucinogenic compounds like psilocybin or muscimol in the fungus. That suggests the mushroom harbors a genuinely new kind of brain-tweaking compound that scientists have never isolated before.
