Basidium



a special form of sporophore, characteristic of basidiomycetous fungi, on which the sexual 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 passed into the four basidiospores.
Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 Various

They are characterized by their principal spores being produced externally, usually in fours, upon an organ called a basidium.
The New Gresham Encyclopedia. Vol. 1 Part 3 Various

During the tetrad division in the basidium nuclear reduction occurs.
Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 Various

This conjugate condition is finally brought to a close by the nuclear fusion in the basidium.
Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 Various

When the four spores are full grown they have consumed all the protoplasm in the basidium.
The Mushroom, Edible and Otherwise M. E. Hard

Between the nuclear association and the nuclear fusion in the basidium many thousands of cell generations may be intercalated.
Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 Various

basidium, the characteristic spore-producing organ of the Basidiomycetes.
The New Gresham Encyclopedia. Vol. 1 Part 3 Various

The sporophyte may be considered to begin at the stage of nuclear association and end with the nuclear reduction in the basidium.
Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 Various

Life-history always very simple, no well-marked alternation of generations; basidium borne directly on the mycelium.
Encyclopaedia Britannica, 11th Edition, Volume 11, Slice 3 Various

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

(bə-sĭd’ē-əm)
Plural basidia
