This European species is closely related to North American Psilocybe cyanescens (which is also spreading throughout Europe). Psilocybe cyanescens cap is not translucent-striate when moist, its lamellae are adnexed or narrowly attached, the veil connecting the pileal margin with the stipe more distinct. It grows in the same sites. Rare. Sporocarps solitary or gregarious. On well decayed deciduous and coniferous wood, on twigs, compost, plant residue, in gardens, parks, on roadsides, in rich places, ruderaly.
