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 psilocybin, which turns into the psychedelic psilocin upon ingestion.^[1] The most potent species are members of genus Psilocybin, such as P. azurescens, P. semilanceata, and P. canescents, but psilocybin has also been isolated from approximately a dozen other genera, including Pan Aeolus (including Copeland), Inocybe, Pluteus, Gymnopilus, and Pholiotina.
