Cryptococcus foliicola sp. nov. and Cryptococcus taibaiensis sp. nov., novel basidiomycetous yeast species from plant leaves

J Gen Appl Microbiol. 2011;57(5):285-91. doi: 10.2323/jgam.57.285.

Abstract

A molecular taxonomic investigation performed on basidiomycetous yeast strains isolated from plant leaves collected in two areas of China revealed two novel species, Cryptococcus foliicola sp. nov. (type strain HS 23.3(T) = AS 2.2471(T) = CBS 9920(T)) and Cryptococcus taibaiensis sp. nov. (type strain ST 7.9(T) = AS 2.2444(T) = CBS 9919(T)), among the non ballistoconidium-forming strains producing cream-colored colonies. These new species differed markedly from closely related species in the internal transcribed spacer (ITS) and 26S rRNA D1/D2 region sequences. They clustered in a strongly supported clade represented by Cryptococcus victoriae in the Tremellales group in the phylogenetic trees drawn from ITS and D1/D2 sequences.
