Lanmaoa asiatica ("jian shou qing" / 见手青) — the Yunnan "little people" bolete
Posting this because it went semi-viral on Chinese social media over the last year or two (#jianshouqing has racked up 100M+ views on Xiaohongshu/Douyin) and I'm surprised it hasn't come up here yet. Recapping what's actually documented, since most English coverage is either tabloid-y ("Janet Yellen ate magic mushrooms") or too thin to be useful.
## What it is
A reddish bolete that grows in symbiosis with pine roots (*Pinus yunnanensis*) in Yunnan, China, and in the Cordillera region of the Northern Philippines (where it's called *Sedesdem*). Chinese name *jianshouqing* (见手青) means "sees the hand, turns blue" — the flesh oxidizes to indigo on cutting/bruising. It's a legitimately prized wild edible, rich in umami — once properly cooked.
## The effect
Eaten raw or undercooked, it reliably produces "Lilliputian hallucinations": vivid visions of numerous tiny (~2–30 cm), fully three-dimensional autonomous people, embedded realistically in your actual physical environment — walking under doors, climbing furniture, scaling walls, obeying normal physics. Not abstract/geometric like classic psychedelics — anchored and detailed.
## Timing (the part that actually matters)
- **Onset: 12–24 hours after eating.** Not minutes, not hours — closer to a full day later.
- **Duration: 1–7 days, sometimes weeks.**
- Insight is preserved throughout — people know they're intoxicated.
- Documented side effects: GI upset, occasional delirium. No deaths linked to it; recovery appears complete.
## Cross-cultural convergence (the genuinely wild part)
The *same* specific hallucination — tiny autonomous people — has been independently reported in Yunnan, the Northern Philippines, and (via an unrelated mushroom, *nonda*) in Papua New Guinea's Western Highlands since the 1930s, with zero historical contact between these groups. Possible written reference in a 3rd-century Daoist text in China.
## The science, as of 2026
Colin Domnauer (PhD student) and mycologist Bryn Dentinger (University of Utah) used DNA sequencing to confirm the Chinese and Philippine mushrooms are the same species — *Lanmaoa asiatica* — published in *Mycologia*, June 2026.
But the active compound is **still unidentified**. Ruled out: psilocybin, muscimol, ibotenic acid — none of the known mushroom hallucinogens show up. What's known about the mystery compound: it's thermolabile (destroyed by cooking, hence why cooked mushrooms are safe), unusually water-soluble/polar, and — per an unconfirmed hypothesis from Domnauer — might be an unusually large protein, possibly acting via the gut or brainstem rather than as a classic small-molecule hallucinogen crossing into the brain. The mushroom can't be cultivated in a lab, so all research depends on wild-collected specimens from Yunnan/Philippines field trips.
## Why it's actually interesting, not just a curiosity
A compound that reliably produces such a specific, narratively consistent hallucination (autonomous *people*, not patterns or colors) across unconnected cultures is a strange result. It suggests whatever process the brain uses to construct "a person" as a perceptual category can be selectively triggered — which has implications for understanding *spontaneous* Lilliputian hallucinations seen in things like Charles Bonnet syndrome, entirely without a mushroom involved.

**The honest caveat, for anyone thinking about this beyond reading:** the delayed onset + multi-day duration combination means there's no real way to "work up to it" the way you might titrate a shorter-acting substance. You commit a full day before you know anything happened, to an effect that could run anywhere from one day to multiple weeks, with no established dose–intensity relationship. Even Domnauer, who's spent years around fresh specimens, has said he hasn't dosed himself, citing the unknown minimum effective dose and the delirium/dehydration risk. Worth having that front of mind before this thread.
turns into a "how do I get some" discussion.
Sourcing dried jianshouqing does turn up in Chinese specialty-food/herbal export listings, though nobody knows whether drying (as opposed to cooking) preserves or destroys the active compound — genuinely unknown either way.
