Sterigmatosporidium gen. n., a new heterothallic basidiomycetous yeast, the perfect state of a new species of Sterigmatomyces fell.
Sterigmatosporidium gen. n. is described as a new basidiomycetous yeast-like fungus with the single species Sterigmatosporidium polymorphum sp. n. for which a Latin diagnosis and a preliminary life cycle are presented. The mean character distinguishing the new genus from the imperfect genus Sterigmatomyces is the development of a dikaryotic mycelium with clamp connections producing sexual spores in ramified whorls and lateral chlamydospores as well as blastospores. The dikaryotic phase could be induced by crossing compatible haploid clones of the heterothallic fungus, which are similar to Sterigmatomyces but not identical with any known species.
