Psilocybin (also known as psilocybine) is a psychedelic indole of the tryptamine family, found in psilocybin mushrooms. It is considered mostly to be an entheogen and a tool in use to supplement various types of practices for transcendence including in meditation, psychonautics, and illicit psychedelic psychotherapy whether self administered or not . Though Psilocybin rarely attracts much attention from mainstream media, when it does, the focus tends to be on the recreational use to the exclusion of any other purpose. It is present in hundreds of species of fungi, including those of the genus Psilocybe, such as Psilocybe cubensis and Psilocybe semilanceata, but also reportedly isolated from a dozen or so other genera. Psilocybin mushrooms are commonly called "magic mushrooms" or more simply "shrooms". The intensity and duration of entheogenic and recreational use of psilocybin mushrooms vary depending on species of mushrooms, dosage, individual physiology, and set and setting.
