ABSTRACT

Twenty-four species of Psilocybe are known from Washington State, USA, of which 20 have been previously reported. Psilocybe pratensis, P. semistriata, and P. subcoprophila are reported for first the time from Washington, and P. semiinconspicua is described as a new species. Moreover, P. angustispora and P. inquilina are discussed in light of new collections reported here. Of the Psilocybe spp. now known from Washington, 10 belong to the hallucinogenic group, including the new species.
