basidium

[bah-sid´e-um] (pl. basi´dia) (L.)

the clublike organ bearing basidiospores.

ba·sid·i·um

, pl.

ba·sid·i·a

(ba-sid'ē-ŭm, -ă),

A cell or spore-bearing organ usually club-shaped that is characteristic of the Basidiomycota. It bears basidiospores externally after karyogamy and meiosis. It is composed of a swollen terminal cell situated on a slender stalk, and gives rise to slender filaments (sterigmata), usually four in number, from the ends of which the basidiospores are developed.
