Abstract:
Sequence analysis of the D1/D2 domains of the large subunit rDNA of Cryptococcus yarrowii (CBS 7417) indicates that this species does not belong to the hymenomycetous fungi, but instead is of urediniomycetous affinity. Therefore, the name change Rhodotorula yarrowii comb. nov. is proposed. The cell wall of the species contains xylose, a character considered by most authors to indicate fungi of hymenomycetous affinity. However, our results show that xylose may occur in minor amounts in the cell walls of urediniomycetous fungi. A high mannose content of the cell walls may be a more reliable character for urediniomycetous yeasts.
