Galerina is a genus of small brown-spored saprobic mushrooms, with over 300 species found throughout the world, from the far north to remote Macquarie Island in the Southern Ocean. Species 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. This group is most noted for toxic species which are occasionally confused with hallucinogenic species of Psilocybe.
