Gymnopilus validipes is a widely distributed mushroom of North America and Europe. Gymnopilus validipes contains the hallucinogens psilocybin and psilocin. The mild taste of this mushroom stands in contrast to closely related bitter species. Validipes means "having a robust stalk." Gymnopilus validipes contains about 0.12% psilocybin.[1]
