Abstract

Three strains of a novel yeast species were isolated from water tanks (phytotelmata) of a bromeliad species collected in the state of Tocantins, Brazil. Analysis of sequences for the region spanning the SSU rRNA gene, the internal transcribed spacer, the 5.8S rRNA gene and the D1/D2 domains of the LSU rRNA gene and RNA polymerase II gene showed that these novel yeasts belong to a species that is distinct from all recognized ascomycetous yeast species. Based on the results of gene sequence analyses, a novel species representing a new genus in the is proposed. The novel species is assigned to the genus gen. nov. The three isolates of the novel yeast species failed to form sexual spores alone or in mixtures. The name sp. nov. is proposed to accommodate these isolates. The type strain of sp. nov. is UFMG-CM-Y311 ( = CBS 13264).
