“…From our gene sequence analyses, the Trichomonascus clade is a single, phylogenetically circumscribed taxonomic group that can be represented by a single ascosporic genus and a single anamorphic genus. Of the two ascosporic genera in this clade, Trichomonascus was described in 1947 (Jackson, 1947) and has taxonomic priority over Stephanoascus, which was described in 1976 with Stephanoascus ciferrii as the type species (Smith et al, 1976). The anamorphic states of this clade are characterized by noticeably denticulate conidiophores, and the species assimilate a number of unusual compounds, which phenotypically separates them from typical species of the anamorphic genus Candida.…”

Relationships among species assigned to the ascosporic yeast genera Sporopachydermia, Stephanoascus, Trichomonascus, Wickerhamiella and Zygoascus, and to the associated anamorphic genera Arxula, Blastobotrys, Sympodiomyces and Trigonopsis, were determined from phylogenetic analyses of gene sequences from the nearly complete large-subunit rRNA gene, the mitochondrial small-subunit rRNA gene, and cytochrome oxidase II. The genus Stephanoascus is polyphyletic, resulting in reassignment of two species to the older genus Trichomonascus and the third to Sugiyamaella gen. nov. (type species Sugiyamaella smithiae). The genera Sporopachydermia, Wickerhamiella and Zygoascus appear to be monophyletic. The species Pichia ofunaensis and P. tannicola are proposed for transfer to Zygoascus. Arxula, Blastobotrys and Sympodiomyces are members of the Trichomonascus clade, with the genus Blastobotrys having taxonomic priority for anamorphic states. Trigonopsis variabilis and three species of Candida represent a distinct clade. From the foregoing gene sequence analyses, the new ascosporic genus Sugiyamaella is proposed, as are 14 new species combinations and the new family Trichomonascaceae.

“…A multigene phylogenetic analysis revealed that T. petasosporus is related closely to Stephanoascus ciferrii, the type species of the genus Stephanoascus (Kurtzman & Robnett, 2007). As Trichomonascus H. S. Jackson (1947) has taxonomic priority over Stephanoascus M. Th. Smith, van der Walt & E. Johannsen (1976), S. ciferrii and the related species Stephanoascus farinosus were transferred to the genus Trichomonascus (Kurtzman & Robnett, 2007).…”
