General Description:

Psilocybe cyanescens has a hygrophanous pileus that is chestnut-brown when moist, fading to pale buff or slightly yellowish. Fresh material always bruises a bluish or blue-green color where damaged, and the staining is still visible after drying. It’s stem is white when undisturbed and bruises easily when damaged. Cap generally measures from 2-5 cm across, distinctly wavy in maturity. Lamellae adnate, light brown to dark purple brown in maturity, with lighter gill edges. An annulus is absent and the spore print is dark purple brown. Microscopically, this species is characterized by common clavate-mucronate pleurocystidia and smooth, elliptical spores which measure 9 – 12 × 6 – 8. The odor and taste is farinaceous.


Distribution:

West coast of the USA from San Diego to Alaska, and Western to Central Europe.


Habitat:

Coastal dune grasses are probably the native habitat for this species.


Look Alikes:

Psilocybe subaeruginascens looks similar but has an annulus and is much less common. Psilocybe “cyanofriscosa” looks similar but is a thicker, meatier mushroom which does not have a cap that gets wavy in age.


Uses:

This species is commonly eaten for its hallucinogenic effect.
