Analyses of nucleotide sequences from the D1/D2 domains of the large-subunit rDNA and phenotypic characteristics showed that the genera and are members of a single, monophyletic clade that would be best represented by a single anamorphic genus. On the basis of taxonomic priority, we propose the transfer of the five species of the genus to the genus . The description of the genus is emended and the following new combinations are proposed: comb. nov., comb. nov., comb. nov., comb. nov. and comb. nov. In addition, ten strains representing a novel yeast species belonging to the clade were isolated from flowers in Thailand, Cuba and Brazil. Analysis of the internal transcribed spacer and D1/D2 large-subunit rDNA sequences indicated that the isolates represent a single species that was distinct from other species of the clade. The name sp. nov. is proposed to accommodate these strains. The type strain is BCC 7726 (=CBS 10551).
