The monotypic genus Babjeviella is an ascomycetous yeast in Debaryomycetaceae. It was described as Pichia inositovora by Golubev et al. (1981) and was revised as Babjeviella inositovora based on the phylogenetic analysis of D1/D2 divergent domains of the large subunit (LSU) and the nearly complete small subunit (SSU) rDNA genes by Kurtzman & Suzuki (2010),. The type species of the genus, Babjeviella inositovora, was isolated from high moor peat in the Moscow region of Russia (Golubev et al. 1981). It produces unconjugated asci with one to four hat-shaped ascospores that are released by ascus evanescence. Some bulb-like structures occasionally form on the brims of ascospores. The species’ homo- or heterothallic status has not been confirmed. Colonies are butyrous with a glistening surface. Budding cells are short ellipsoids to elongate, with multilateral budding on a narrow base. Babjeviella inositovora can use inositol as the only source of carbon and forms coenzyme Q-9 (Kurtzman and Suzuki. 2010).
