The products of teliospore germination in Ustilago triodiae and Sporisorium loudetiae-pedicellatae are illustrated. In U. triodiae the transversely-septate basidium is usually three-spored. The sporidia (basidiospores) either bud or form surface hyphae from which branched systems of aerial sporidia arise. A similar haplophase occurs in some other species.

In S. loudetiae-pedicellatae the basidium is unicellular and produces up to four sporidia in succession. These give rise to colonies composed largely of similar cells. No conjugation was seen in either species.
