In biology, a sterigma (pl.: sterigmata) is a small supporting structure. It commonly refers to an extension of the basidium (the spore-bearing cells) consisting of a basal filamentous part and a slender projection which carries a spore at the tip. [1]

The meaning of STERIGMA is one of the slender stalks at the top of the basidium of some fungi from the tips of which the basidiospores are formed; broadly : a stalk or filament that bears conidia or spermatia.

Sterigma (pl. Sterigmata). A sterigma is an apical extension of the basidium that bears the basidiospores; it is elongated in Auriculariales and Platygloeales. There are usually four sterigmata on each basidium.

A typical basidium is a club-shaped structure, usually with four prongs at one end. Each such prong is called a sterigma (with sterigmata the plural form) and the spores develop at the tips of the sterigmata. Here is a stylized drawing of a basidium, shown in green, with four brown spores.

The size varies, but a typical spore is about 10 microns, or 1/2,500th of an inch, in width, and it is attached at the end of a stalk called a sterigma. From New York Times “There’s a point at the …

6 days ago · (pl. sterigmata)A small spore-bearing stalk found in certain fungi. In the Basidiomycota, sterigmata develop as outgrowths of a basidium, each bearing a basidiospore at its tip.

Fungi that bear their spores on basidia are known as basidiomycetes, and are placed in the phylum Basidiomycota. The spores are usually attached to the basidium by short spikes called sterigmata (singular: sterigma). There are usually four sterigmata (and four spores) to a basidium. Basidia which bear only two spores are called bisterigmate.

sterigma noun. A slim projecting part of the basidium of some species of fungi that carries the basidiospore.
