Psilocybe samuiensis is a species of psychedelic mushroom in the family Hymenogastraceae, which has psilocybin and psilocin as its main active compounds. It was placed in the section Mexicanae of genus Psilocybe by Gastón Guzmán due to its rhomboid-shaped spores. It has been found in Koh Samui, a small tropical island in Thailand, where some psychoactive species are consumed by both natives and tourists. Chao Samui rarely consume psilocybian fungi. Such local use is usually restricted to local females who do so at the request of foreigners.[1][2]
