Abstract
Small subunit ribosomal DNA sequences of all species of the basidiomycetous anamorphic yeast genus Trichosporon were determined, and phylogenetic trees were constructed by the neighbor-joining and maximum likelihood methods. The sequence data showed that, with the exception of T. pullulans, the genus is monophyletic, although its members have two different major ubiquinones, Q9 and Q1O. The genus can be divided phylogenetically into three major clusters. Species with Q1O as the major ubiquinone constitute a single cluster, while those with Q9 form two clusters. Trichosporon pullulans was phylogenetically distinct from other taxa of the genus. It is located in a cluster containing Cystofilobasidium capitatum, Mrakia frigida, Xanthophyllomyces dendrorhous and three species of Udeniomyces. This result suggests that T. pullulans does not belong to the genus Trichosporon.
