Where it grows wild

Ecology is not documented in the sources reached; Mexican highland Psilocybe of this kind typically fruit on soil among grass, moss or litter in pine-oak country during the rains.

Records carry no elevation; the Hidalgo site is highland (roughly 2000 m or more judging by the cool nights).
