Psilocybe mexicana Solitary or in small groups among moss along roadsides and trails, humid meadows or cornfields, particularly in the grassy areas bordering deciduous forests, and limestone regions. Common at elevations between 1000-1800 feet, rare in lower elevations, known only from Mexico and Guatemala. Fruiting takes place from May to October.
==Consumption and cultivation==
Like several other psychedelic mushrooms in the same genus, P. mexicana has been consumed by indigenous Central American peoples for its entheogenic effects. In the Nahuatl language, the fungus is known as Teonanácatl—agglutinative form of the words teó(ti) ("god") and nanácatl ("mushroom")—"god-mushroom."
In the western world, usually the sclerotia of p. mexicana ('Mexicana A' strain) are cultivated for psychedelic use. The sclerotia have a lower content of active substances than the actual mushrooms themselves. These are traded under the pseudonym truffles.
