A new species, Trichosporon domesticum Sugita, Nishikawa et Shinoda, is proposed for a strain isolated from the house of a summer-type hypersensitivity pneumonitis patient in Kumamoto, Japan. The nuclear DNA of T. domesticum showed intermediate relatedness to that of T. montevideense; however, their genome sizes were significantly different. These findings suggest that they represent separate species. T. domesticum is distinguished from T. montevideense by its inability to assimilate D-arabinose, ribitol, and dulcitol. The type strain of T. domesticum is strain M 9401, which has been deposited in the Japan Collection of Microorganisms as JCM 9580.
