Psilocybe tampanensis spores is a very rare psychedelic mushroom in the family Hymenogastraceae. Originally collected in the wild in a sandy meadow near Tampa, Florida, in 1977, the fungus would not be found in Florida again until 44 years later. The original Florida specimen was cloned, and descendants remain in wide circulation. The fruit bodies (mushrooms) produced by the fungus are yellowish-brown in color with convex to conic caps up to 2.4 cm (0.9 in) in diameter atop a thin stem up to 6 cm (2.4 in) long. Psilocybe tampanensis forms psychoactive truffle-like sclerotia that are known and sold under the nickname “philosopher’s stones”. The fruit bodies and sclerotia are consumed by some for recreational or entheogenic purposes. In nature, sclerotia are produced by the fungus as a rare form of protection from wildfires and other natural disasters. buy

Legal status

Psilocin and psilocybin are scheduled drugs in many countries, and mushrooms containing them are prohibited by extension. In the United States, Federal law was passed in 1971 that put the psychoactive components into the most restricted schedule I category. For about three decades following this, several European countries remained relatively tolerant of mushroom use and possession. In the 2000s (decade), in response to increases in prevalence and availability, all European countries banned possession or sale of psychedelic mushrooms; the Netherlands was the last country to enact such laws in 2008. However, they did not include psilocybin-containing sclerotia in the 2008 law, and thus, psilocybin-containing fungal compounds are available commercially in the Netherlands. In parallel legal developments in Asia, P. tampanensis was one of 13 psychoactive mushrooms specifically prohibited by law in Japan in 2002
