Psilocybe galindoi

Psilocybe galindoi is a psychedelic mushroom in the section Mexicana, having psilocybin and psilocin as its main active compounds. It is also known as Psilocybe galindii. The species was named in honor of Mr. Carlos Galindo Arias and his family by Dr. Gastón Guzmán.

Distribution and habitat
Psilocybe galindoi is found growing gregariously in soil at higher elevations and in tall grass in or near Pinus-Quercus (pine with oak) forests in Mexico. The holotype location is Pie de la Cuesta, Jalisco, Mexico - a bit south of Guadalajara.

Consumption and cultivation
Like several other psilocybin mushrooms in the genus, a mushroom going under the name Psilocybe galindoi has been consumed by indigenous North American and Central American peoples for its entheogenic effects. This is a misidentification, as the mushroom they are cultivating is Psilocybe tampanensis, and the real Psilocybe galindoi is a synonym of Psilocybe mexicana.

In the Western world, sclerotia of a mushroom misidentified as Psilocybe galindoi are sometimes cultivated for entheogenic or medicinal use. The sclerotia usually have a lower content of active substances than the actual mushrooms themselves.
