Psilocybe mairei
Species of fungus
Psilocybe mairei is a species of mushroom in the family Hymenogastraceae. It is found in Algeria and Morocco and contains the psychoactive compound psilocybin.[1] The oldest example of rock art suggesting use of psychedelic mushrooms might depict P. mairei. In 1992 the Italian ethnobotanist Giorgio Samorini reported finding a painted mural from Tassili n'Ajjer in the Sahara desert in southeast Algeria, dated 7000 to 9000 BCE, portraying mushrooms[2] (later tentatively identified as P. mairei[3]).
