Genus: Galerina
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. The adjective hygrophanous refers to the colour change of mushroom tissue (especially the pileus surface) as it loses or absorbs water, which causes the pileipellis to become more transparent when wet and opaque when dry.
They are often found growing on wood, and when on the ground have a preference for mossy habitats. Many of this species are poisonous.
