Inocybes (known as Fiber Caps) are a large genus of mushroom-forming fungi with over 1400 species, including all forms and variations. Many species of the genus Inocybe are muscarine-containing mycorrhizal mushrooms, ubiquitous around the world.
Do not use this information to pick genus Inocybe mushrooms in the wild as many of the species contain muscarine, a water soluble toxic alkaloid found in certain mushrooms, particularly in Inocybe and Clitocybe species. It causes profound parasympathetic activation that may end in convulsions and death. Inocybe species are not considered suitable for consumption, although in some underdeveloped countries certain species of Inocybe mushrooms are eaten.
