| In the young stage the basidia in the Hypogi are easily distinguished by the aid of the microscope. |
| These cystidia extend above the basidia, and the ends are rounded so that sometimes they appear capitate. |
| Then there will be either lamellae, or gills, or pores, with hymenial layers bearing the basidia. |
| 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. |
