Phylogenetic analyses of the D1/D2 domains of the large subunit rRNAs and translation elongation factor 1 alpha genes (TEF1-α) revealed that five strains of two species from the soil in Furano-shi, Hokkaido were related to Dipodascopsis anomala and 29 strains representing 12 species from soils in Kamogawa-shi, Chiba and Iriomote Island, Okinawa were in the Myxozyma clade. The two species of Dipodascopsis form globose or ellipsoid ascospores in their sac-like ascus and pseudohyphae. Furthermore, these species produce ascospores in their pseudohyphae and do not produce an acicular ascus, which is common among the three species including D. anomala. Therefore, we propose transferring D. anomala to the genus Babjevia and amending Babjevia. Two novel species were described and included in the genus Babjevia: Babjevia hyphoforaminiformans sp. nov. (holotype NBRC 111233; MycoBank no. MB 829051) and Babjevia hyphasca sp. nov. (holotype NBRC 112965; MycoBank no. MB 829053). The 12 species in the Myxozyma clade produce neither ascospores nor pseudohyphae and have different characteristics in assimilating several carbon sources from each other. Thus, we propose that the novel species of Lipomyces be classified as forma asexualis (f.a.). From Kamogawa-shi, Chiba (19 strains representing five species): Lipomyces melibiosiraffinosiphilus f.a., sp. nov. (holotype NBRC 111411; MycoBank no. MB 829034), Lipomyces kiyosumicus f.a., sp. nov. (holotype NBRC 111424; MycoBank no. MB 829035), Lipomyces chibensis f.a., sp. nov. (holotype NBRC 111413; MycoBank no. MB 829036), Lipomyces kamogawensis f.a., sp. nov. (holotype NBRC 112967; MycoBank no. MB 829037), Lipomyces amatsuensis f.a., sp. nov. (holotype NBRC 111420; MycoBank no. MB 829041). From Iriomote island, Okinawa (10 strains representing seven species): Lipomyces taketomicus f.a., sp. nov. (holotype NBRC 112966; MycoBank no. MB 829042), Lipomyces yaeyamensis f.a., sp. nov. (holotype NBRC 110433; MycoBank no. MB 829050), Lipomyces iriomotensis f.a., sp. nov. (holotype NBRC 110436; MycoBank no. MB 829045), Lipomyces haiminakanus f.a., sp. nov.
