Rhodotorula rosulata sp. nov., Rhodotorula silvestris sp. nov. and Rhodotorula straminea sp. nov., novel myo-inositol-assimilating yeast species in the Microbotryomycetes

Three novel species are described as Rhodotorula rosulata sp. nov. (type strain VKM Y-2962^T =CBS 10977^T), Rhodotorula silvestris sp. nov. (type strain VKM Y-2971^T =CBS 11420^T) and Rhodotorula straminea sp. nov. (type strain VKM Y-2964^T =CBS 10976^T) based on the study of eight isolates from needle litter. The new species, phylogenetically located within the Microbotryomycetes, are related to glucuronate-assimilating species of the genus Rhodotorula. Sequencing of the D1/D2 domains of the LSU rDNA gene and the internal transcribed spacer (ITS) region, as well as physiological characterization, revealed their distinct taxonomic positions.
