Psilocybe subfimetaria

Psilocybe subfimetaria is a Pacific Northwest species described by Guzmán and A.H. Smith in 1978 from a Vancouver type collection, with later records from Oregon and a mulched garden in Seattle. It fruits in late autumn on rich, disturbed ground. Conditions are based on one measured Seattle site and the maritime climate. Many Psilocybe species contain psilocybin, a controlled substance in many countries; check local law before cultivating.
