Common Names
🌍 LocalJian shou qing, See-hand-blue, Sedesdem (Filipinas)
Description
Bolete mushroom native to Yunnan, China (with relatives in the Philippines). It is culinarily appreciated, but if consumed raw or undercooked, it causes intense "Lilliputian hallucinations," a clinical syndrome that causes consistent visions of miniature people ("dwarfs"). The active metabolite is currently a scientific mystery; it does not contain psilocybin or ibotenic acid.
Ecology
Mycorrhizal in fagaceous and pine forests, endemic to Asia (western China and the Philippines).
