Galerina

About

Galerina is a genus of small brown-spore saprobic mushroom-bearing fungi, with over 300 species found throughout the world. Galerina mushrooms are typically small and hygrophanous, with a slender and brittle stem. They are often found growing on wood, and when on the ground have a preference for mossy habitats. The genus is noted for some extremely poisonous species which are occasionally confused with hallucinogenic species of Psilocybe or with edible species.
