A mushroom, also sometimes called a toadstool, is the part of a fungus that produces and releases spores, special cells that can grow into a new fungus. Most mushrooms have a stem (stipe), cap (pileus), and gills (lamellae), but some fungi without stems are still said to have mushrooms. Many types of mushrooms are eaten by both humans and animals; however, there are several poisonous mushrooms, so you should never pick and eat wild mushrooms.
