At the microscopic level the basidiospores are shot off basidia and then fall between the gills in the dead air space.
Basidiomycota are filamentous fungi composed of hyphae (except for yeasts), and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four).
A single species may produce up to five morphologically and cytologically distinct spore-producing structures viz., spermagonia, aecia, uredinia, telia, and basidia in successive stages of reproduction.
Occasionally, monokaryons of some taxa can form morphologically fully formed basidiomes and anatomically correct basidia and ballistic basidiospores in the absence of dikaryon formation, diploid nuclei, and meiosis.
Occasionally, basidiospores are not formed and parts of the "basidia" act as the dispersal agents, e.g. the peculiar mycoparasitic jelly fungus, Tetragoniomyces or the entire "basidium" acts as a "spore", e.g. in some false puffballs ( Scleroderma ).
