title: A new genus: Sporopachydermia.
abstract: In two species of the yeast genus Cryptococcus ascospores have been found. A genus is described to accommodate the two species, because the spore wall is extraordinarily thick and its ultrastructure differs from that found in all other yeast genera. The spores are easily liberated from the ascus at maturation. The name Sporopachydermia is proposed for the genus and the names S. lactativora and S. cereana are proposed for the species.
