At the apex of each basidium a flask-shaped cell, "sterigma" (d), appears.
On top of the basidia are minute stalk-like branches, called sterigmata (singular sterigma), and each branch carries a naked spore.
At free end of each sterigma is formed an oval body -- a spore or
At the apex of each sterigma appears a row of oval cells -- "spores" or
Two or more gonidia may be supported upon each sterigma.
From each one of these cells of the basidium a long, slender process (sterigma) grows out to the surface of the plant and bears the spore.
In our plants, which seem to be typical, the spores are nearly globose, varying to oval, and with the minute point where the spore was attached to the sterigma at the smaller end, the spores usually being finely granular, 6 -- 9 µ in diameter, and rarely varying towards short elliptical, showing a tendency to approach the shape of the spores of
The additional energy is probably consumed in severing the connection between the spore and its perch (sterigma).
