Hallucinogenic bolete mushroom
Hallucinogenic bolete mushrooms, also known as psychoactive bolete mushrooms or as "xiao ren ren" mushrooms, are bolete mushrooms that produce hallucinogenic effects and are a type of hallucinogenic mushroom. They have been reported in Papua New Guinea, China, and the Philippines.
The exact species of the mushrooms, their active constituents, and their mechanism of action have all yet to be fully clarified. However, among the most frequently implicated species is Lanmaoa asiatica. Hallucinogenic bolete mushrooms are said to make people see the "xiao ren ren" or "little people" and hence to experience Lilliputian hallucinations. Lilliputian hallucinations are a unique type of hallucination and are not necessarily consistent with the hallucinogenic effects of other psychoactive mushrooms.
Other much more well-known hallucinogenic mushrooms include psilocybin-containing mushrooms (which contain the serotonin 5-HT2A receptor agonist and serotonergic psychedelic psilocybin) and Amanita muscaria mushrooms (which contain the GABAA receptor agonist and dissociative hallucinogen muscimol).
