Interpretive Summary: The identification of yeasts using conventional growth tests is often difficult. This problem was recently solved by determining the molecular sequence of a diagnostic gene (genetic material) from all known yeasts, thus permitting rapid species identification. Three yeasts that appeared unique were sequenced and the sequences compared with the all-species database. This analysis revealed that the species are new to science, and they are formally described. Two of the species are closely related to known species, but one is only distantly related to other known yeasts, and it will prove important for understanding the overall classification of yeasts.

Technical Abstract: Three new species of Candida are described and were determined to be genetically isolated from all other currently accepted ascomycetous yeasts from their sequence divergence in the species-variable D1/D2 domain of large subunit (26S) ribosomal DNA. One of the species was isolated from an ambrosia beetle while the other two were from the frass of wood boring beetle larvae. The new species and their type strains are the following: C. ontarioensis NRRL YB-1246 (CBS 8502), C. tammaniensis NRRL Y-8257 (CBS 8504) and C. trypodendroni NRRL Y-6488 (CBS 8505).
