The evolutionary relationships for 43 species in the taxa of the basidiomycetous yeast and related yeast-like fungi have been studied from the 43 18S rRNA partial sequences. Fibulobasidium inconspicuum showed a relatively close relationship to Filobasidiella neoformans. It is obvious that Tremella foliacea and Ustilogo rabenhorstiana form a independently different cluster from basidiomycetous yeast and seem to be phylogenetically distant from basidiomycetous yeast and each other. The basidiomycetous yeasts are believed more closely associated with Tremella foliacea than with Ustilago rabenhorstiana. The phenotypic criteria such as carotenoid pigments, teliospores, ballistospores seems not to be phylogenetically useful indicators.
