Sporobolomyces lactosus is a pink yeast-like fungus that is not congeneric with other members of Sporobolomyces (Basidiomy-cota, Microbotryomycetes, Sporidiobolales). During our ongoing studies of pink yeasts we determined that S. lactosus was most closely related to Pseudeurotium zonatum (Ascomycota, Leotiomycetes, Thelebolales). A molecular phylogenetic analysis using sequences of the ITS region and the small and large subunit (SSU, LSU) rRNA genes, indicated that four isolates of S. lactosus, including three ex-type isolates, were placed in Thelebolales with maximum support. A new genus is proposed to accommodate S. lactosus, Inopinatum. This is the first pink yeast reported in Leotiomycetes.
