Detailed explanation-1: -A basidium ( pl. basidia) is a microscopic sporangium (a spore-producing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium, developed from secondary mycelium.

Detailed explanation-2: -Gilled mushrooms have basidia located on the gills on the underside of the cap. The spores are dropped from the gills when mature. In boletes, the basidia are located in tubes within the flesh of the cap of the mushroom. The spores are released through pores in the surface of the underside of the cap.

Detailed explanation-3: -The Basidiomycota bear their sexual spores externally on a usually club-shaped structure called a basidium, which is often borne on or in a fruiting body called a basidiocarp or basidiome (Fig.

Detailed explanation-4: -The basidium is a clublike structure with 2–4 apical sterigmata that bear basidiospores. It is usually entire but is divided longitudinally in Auriculariales and Platygloeales.

Detailed explanation-5: -A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia.
