Psychedelic mushroom

Psilocybin mushrooms, also known as psychedelic mushrooms, are mushrooms that contain the psychedelic compounds psilocybin and psilocin. Common colloquial terms include magic mushrooms and shrooms. They are used mainly as an entheogen and recreational drug whose effects can include euphoria, altered thinking processes, closed and open-eye visuals, synesthesia, an altered sense of time and spiritual experiences. Biological genera containing psilocybin mushrooms include Copelandia, Galerina, Gymnopilus, Inocybe, Mycena, Panaeolus, Pholiotina, Pluteus, and Psilocybe. Over 100 species are classified in the genus Psilocybe.

Psilocybin mushrooms may have been used since prehistoric times. They are possibly depicted in Stone Age rock art in Europe and Africa, and have a history of use in pre-Columbian Mesoamerica. Many cultures have used these mushrooms in their religious rites and ceremonies.

Archaeological evidence suggests that psilocybin-containing mushrooms have been used by humans since prehistoric times. It has been argued that prehistoric rock art near Villar del Humo, Spain, offers evidence that Psilocybe hispanica was used in religious rituals 6,000 years ago, and that art at the Tassili caves in southern Algeria long shaft member from 7,000 to 9,000 years ago may show the species Psilocybe mairei.
