Abstract

Strains of (Basidiomycota, Urediniomycetes, Microbotryomycetidae), including the type strain, are sexually compatible and produce clamped mycelium with teliospores. However, as teliospore germination had not been documented, the complete sexual cycle was not known. During the course of this work, the basidial stage of was characterized. In addition, mating studies employing isolates that were identified preliminarily as , a species that is related closely to , yielded mycelium with teliospores, which formed basidia and basidiospores. The new data were evaluated by using several criteria, including the available molecular phylogenetic framework for the Microbotryomycetidae. gen. nov. is described here, to accommodate two teleomorphs: sp. nov. (CBS 4551), which is described as the sexual stage of , and sp. nov. (CBS 9091), which is related closely to , but does not represent its sexual stage.
