Guzmán & J. M. Trappe
Psilocybe semiinconspicua is a psilocybin mushroom in section Semilanceatae native to the state of Washington in the United States. The mushroom is small, rare, difficult to see and stains blue where damaged. It can be mistaken for Psilocybe silvatica and can be distinguished by its more conic cap, narrower spores and narrower cheilocystidia.
This mushroom is only known from the type locality where it was found at the Glacier Peak Wilderness Area in Wentachee National Forest, Washington, USA.
The gills are Adnate light grayish brown at first, turning dark purple as the spores mature.
Psilocybe semiinconspicua is gregarious in small groups among shrubs on a creek bank.
