They resemble each other very much, except that the basidia bear four sterigmata and a spore on each.
basidia transversely septate; no teleutospores; saprophytes.
Paraphyses (sterile cells) and sometimes cystidia (longer sterile cells) or spines are intermingled with the basidia.
Parasites without fruit-body; basidia exposed on surface of host.
The basidia, spicules, and quaternate spores agree with those of Agaricini.
In the young stage the basidia in the Hypogi are easily distinguished by the aid of the microscope.
The basidia are nearly round with four rather stout, elongated sterigmata, spores very nearly round.
The basidia are abruptly club-shaped, rather distant and separated regularly by rounded cells, four spored.
Most of Basidiomycetes are characterized by the large sporophore on which the basidia with its basidiospores are borne.
The spore-bearing cells are basidia; the others are called paraphyses.
basidium ba·sid·i·um (bə-sĭd'ē-əm)
n. pl. ba·sid·i·a (-ē-ə)
A small club-shaped structure typically bearing four spores at the tips of minute projections, unique to Basidiomycetes and used as a distinguishing characterisitic.
