Mushroom

Amushroom(ortoadstool) is the fleshy,sporebearingfruiting bodyof afungus, typically produced above ground on soil or on itsfoodsource. The standard for the name mushroom is the cultivated white button mushroom,Agaricus bisporus; hence the word mushroom is most often applied to those fungi (Basidiomycota,Agaricomycetes) that have a stem (stipe), a cap (pileus), and gills (lamellae, sing.lamella) or pores on the underside of the cap. These pores or gills produce microscopicsporesthat help the fungus spread across the ground or its occupant surface.
