The Mystery Of The Mushroom That Makes You See Tiny People
The Mystery Of The Mushroom That Makes You See Tiny People A few moths ago a researcher published his findings on a mysterious mushroom that reliably produces lilliputian hallucinations when eaten raw. I was one of the first to report on it, ” Luke recounts a story that captures it perfectly: a professor from Yunnan, aware of the mushroom’s reputation, ate some and waited for the little people to appear. But nothing happened. Disappointed, he lifted the tablecloth, and lo and behold found hundreds of xiao ren ren, marching in formation underneath The Mystery Of The Mushroom That Makes You See Tiny Peopleasiatica itself was only formally described and named in 2015.
The hospitalisation data says that somewhere between 69% and 91% of people hospitalised after eating these mushrooms report hallucinations, with no fatalities and no abnormal vital signs recorded. The body, it seems, tolerates whatever this is remarkably well. The mind is another matter.
A Compound We Haven’t Identified Yet
The scientific puzzle at the centre of all this is that nobody knows what’s causing it. A research team at the University of Utah, led by doctoral student Colin Domnauer under expert mycologist Professor Bryn Dentinger, has been working to identify the active compounds.
They’ve ruled out the obvious candidates like psilocybin and psilocin (from Psilocybe species) and muscimol (from Amanita muscaria). Whatever is producing these visions is chemically distinct from anything we’ve characterised before.

What makes Luke’s article particularly interesting is the wider pattern he traces. The xiao ren ren aren’t unique to L. asiatica. Reports of tiny beings (elves, pixies, dwarves, gnomes, soldiers) appear across a surprisingly wide range of psychedelic experiences.
DMT is the most discussed. Terence McKenna famously declared: “You get elves, everybody does.” The data is more nuanced. Survey research across around 2,500 people reporting entity encounters with DMT found that only 14-27% reported encounters with little people specifically. Luke’s own field research, observing people taking high-dose DMT directly, found the figure closer to 3%. The little folk, as he drily puts it, “just don’t like being watched.”
But the phenomenon also appears with ayahuasca, peyote, and according to Luke’s own account, with Brugmansia (floripondio) – the delirious, anticholinergic plant in the Datura family. At a parapsychology conference in Brazil in 2010, Luke and a group of colleagues appear to have been unknowingly dosed with it. His account of the subsequent minibus journey is one of the stranger pieces of experiential reporting I’ve read in psychedelic literature.
The appearance of tiny beings across such a pharmacologically diverse set of substances is something that neither mainstream neuroscience nor psychedelic science has really gotten to grips with. Is there a specific neural signature that generates “miniaturised human-like entity” as a hallucination category? Is there something in the structure of certain altered states that the human perceptual system resolves into the little people? We don’t know.
Why This Matters for the Broader Field
From a mycological standpoint, L. asiatica is a reminder that the psilocybin conversation, as important as it is, represents a tiny slice of what fungi are doing chemically. Luke draws an interesting parallel: Pochonia chlamydosporia, a worm-hunting fungus, produces ketamine. Periglandula clandestina, an endophyte infecting morning glory seeds, produces lysergic acid. These are evidence of a kingdom that has been synthesising neuroactive compounds far longer than we’ve been studying them.
The Lilliputian mushroom is probably not going to become a clinical intervention. The visions it produces are fascinating but not exactly controlled, the compound is so far unidentified, and the dose-response is unclear. But it still an important mystery to solve because it expands the map.
Every new psychoactive compound from the fungal kingdom is a new data point. A new key that might eventually unlock something about how consciousness works, how the brain constructs reality, and why human minds across cultures and centuries keep populating their altered states with the same cast of tiny, mischievous beings.
The Pattern That Won’t Go Away
Humans have been encountering “the little people” for as long as we have records. Tylwyth Teg in Wales, Tír na nÓg in Celtic mythology, xiao ren ren in Yunnan, the Guaraní spirits of Brazil, pixies, elves and fairies just to name a few. These encounters happen in ceremony, in dreams, in illness, in psychedelic experiences, and occasionally in ordinary life.
There are connections running beneath the surface of these reports that we haven’t fully mapped yet. The fungal kingdom and the human nervous system have been in relationship for a very long time. Whatever L. asiatica is doing, it’s tapping into something old.
