Psilocybe stuntzii, also known as Stuntz's blue legs and blue ringers it is a psilocybin mushroom of the family Hymenogastraceae, having psilocybin and psilocin as main active compounds.

Habitat and distribution

Psilocybe stuntzii is found growing scattered to gregarious to cespitose, rarely solitary, in conifer wood chips and bark mulch, in soils rich in woody debris, and in new lawns of freshly laid sod or any newly mulched garden throughout the western region of the Pacific Northwest.[2] It appears from late July through December, being observed all year long in the Seattle area, also reportedly appearing in California, rarely as far south as Santa Cruz. There was a time when this mushroom appeared in over 40 percent of all new lawns and mulched in areas in the Puget Sound region of the Pacific Northwest. Due to a disappearance of pastures south of Seattle in the Tukwila-Kent-Auburn areas, this mushroom now only appears sporadically in certain new lawns which are well fertilized and manicured.[citation needed]


This mushroom is hallucinogenic. Additionally, it closely resembles the highly toxic Galerina marginata, and several poisonings have been attributed to collectors consuming G. marginata after mistaking them for hallucinogenic P. stuntzii.[3]
