Basidium
a special form of sporoph-r-, characteristic of basidiomycetous fungi, on which the s-xual spores are borne, usually at the tips of slender projections.
historical examples
c, a basidium before the four nuclei derived from the secondary nucleus of the basidium have p-ssed into the four basidiospores.

they are characterized by their princ-p-l spores being produced externally, usually in fours, upon an organ called a basidium.

during the tetrad division in the basidium nuclear reduction occurs.

this conjugate condition is finally brought to a close by the nuclear fusion in the basidium.

between the nuclear -ssociation and the nuclear fusion in the basidium many thousands of cell generations may be intercalated.

basidium, the characteristic spore-producing organ of the basidiomycetes.

the sporophyte may be considered to begin at the stage of nuclear -ssociation and end with the nuclear reduction in the basidium.

life-history always very simple, no well-marked alternation of generations; basidium borne directly on the mycelium.

there is also a further reduction in that the basidium is not derived from a teleutospore but is borne directly on the mycelium.

basidium
(bə-sĭd’ē-əm)
plural basidia
a small, specialized, club-shaped structure typically bearing four basidiospores at the tips of minute projections in the fungi known as basidiomycetes. the basidium is unique to basidiomycetes and distinguishes them from other kinds of fungi.
