Hallucinogenic mushroom in the context of "Psilocybin mushroom"

Hallucinogenic bolete mushrooms, also known as psychoactive bolete mushrooms or as "xiao ren ren (小人人)" 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, a species first described in 2015. 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.

Psilocybin mushrooms, or psilocybin-containing mushrooms, commonly known as magic mushrooms or as shrooms, are a type of hallucinogenic mushroom and a polyphyletic informal group of fungi that contain the prodrug psilocybin, which turns into the psychedelic psilocin upon ingestion. The most potent species are members of genus Psilocybe, such as P. azurescens, P. semilanceata, and P. cyanescens, but psilocybin has also been isolated from approximately a dozen other genera, including Panaeolus (including Copelandia), Inocybe, Pluteus, Gymnopilus, and Pholiotina.

Amongst other cultural applications, psilocybin mushrooms are used as recreational drugs. Psilocybin mushrooms were used ritualistically in pre-Columbian Mexico, but claims of their widespread ancient use are largely exaggerated and shaped by modern idealization and ideology.
