Genera of psilocybin-producing fungi
Psilocybin is produced across multiple genera of fungi — the result of convergent biochemical evolution. Each profile covers taxonomy, ecology, distribution, and the notable species in research and the field.
Gymnopilus
Gymnopilus P. Karst.
A genus of medium to large wood-decay mushrooms known as 'rustgills' for their distinctive rusty orange coloration. Several species produce psilocybin and related tryptamines.
Browse genus
Panaeolus
Panaeolus (Fr.) Quél.
A coprophilic genus of small, dark-spored mushrooms. A minority of species produce significant levels of psilocybin and psilocin.
Browse genus
Pluteus
Pluteus Fr.
A large, diverse genus of wood-decay mushrooms with distinctive free gills and pink spore prints. A small subset of species produces psilocybin.
Browse genus
Psilocybe
Psilocybe (Fr.) P. Kumm.
The most studied genus of psilocybin-containing fungi. Includes the species most prominent in research, cultural history, and contemporary clinical trials.
