In the young stage the basidia in the Hypogi are easily distinguished by the aid of the microscope. |
Most of basidiomycetes are characterized by the large sporophore on which the basidia with its basidiospores are borne. |
At the microscopic level the basidiospores are shot off basidia and then fall between the gills in the dead air space. |
After a few more days of incubation, the ends of some mycelia may enlarge and form basidia within which nuclear fusion and meiosis may occur. |
The basidia are abruptly club-shaped, rather distant and separated regularly by rounded cells, four spored. |
Paraphyses and sometimes cystidia or spines are intermingled with the basidia. |
