Mushroom Biscuit

The farmed white button mushroom, Agaricus bisporus, is the standard for the name "mushroom," so the term "mushroom" is most generally used to refer to fungus (Basidiomycota, Agaricomycetes) with a stem (stipe), a cap (pileus), and gills (lamellae, sing. lamella) on the underside of the cap. The name "mushroom" is used to designate the fleshy fruiting bodies of several Ascomycota, as well as a range of other gilled fungi with or without stems. These gills create minute spores, which aid in the spread of the fungus across the ground or the occupant's surface.

More specific names are given to forms that deviate from the typical morphology, such as "bolete," "puffball," "stinkhorn," and "morel," and gilled mushrooms are often referred to as "agarics" because of their resemblance to Agaricus or their appearance.
