Cryptococcus humicola, as currently defined, shows intraspecific rRNA gene sequence differences. Three strains of this species produced arthroconidia on cornmeal agar and belonged to the genus Trichosporon in a molecular phylogeny. They clustered with the species possessing Q10 as the major ubiquinone and were serotype I. Sequence analyses clearly revealed that they were two new Trichosporon species. The names Trichosporon dermatis sp. nov. (= CBS 2043T) and Trichosporon debeurmannianum sp. nov. (= CBS 1896T) are proposed for these strains.
