| Most of basidiomycetes are characterized by the large sporophore on which the basidia with its basidiospores are borne. |
| The basidia are abruptly club-shaped, rather distant and separated regularly by rounded cells, four spored. |
| Then there will be either lamellae, or gills, or pores, with hymenial layers bearing the basidia. |
| They resemble each other very much, except that the basidia bear four sterigmata and a spore on each. |
| At the microscopic level the basidiospores are shot off basidia and then fall between the gills in the dead air space. |
| In the young stage the basidia in the Hypogi are easily distinguished by the aid of the microscope. |
