Abstract

During a survey of carotenogenic yeasts carried out in north-western Patagonia (Argentina), several ballistoconidia-producing strains belonging to the order Sporidiobolales were isolated from aquatic environments. Five strains were found to represent two novel species, for which the names and are proposed, with CBS 9654 (=PYCC 5818=CRUB 1044) and CBS 9657 (=PYCC 5817=CRUB 1038) as the type strains, respectively. The elongated basidia, which are five to six times longer that those of the remaining species of the genus , are a particular micromorphological feature of . On the basis of the sequences of the D1/D2 domains of the 26S rRNA gene, the species most closely related to is , whereas is the closest relative of . Complete internal transcribed spacer sequence analysis confirmed the separate position of , whereas for no nucleotide differences were found with respect to CBS 491. Negative mating experiments between strains of and strains of together with the low DNA–DNA reassociation values for the type strains of the two species validated the proposal of as a distinct species. Information on additional Patagonian isolates is also included in this report.
