Abstract
Among yeasts isolated from plant leaves collected in different regions of China that form whitish or yellowish colonies and symmetrical ballistoconidia, four strains were shown to represent three novel Bullera species by conventional and molecular taxonomic characterization. The novel species are described as Bullera cylindrica sp. nov. (type strain CB 169T = AS 2.2308T = CBS 9744T), Bullera hubeiensis sp. nov. (type strain HX 19.3T = AS 2.2466T = CBS 9747T) and Bullera nakasei sp. nov. (type strain HX 15.5T = AS 2.2435T = CBS 9746T). These three species, and another eight previously described Bullera species represented by Bullera mrakii, formed a strongly supported distinct clade among the hymenomycetous yeasts in each of the phylogenetic trees drawn from the 26S rDNA D1/D2 domain and the internal transcribed spacer region sequences.
