Abstract
Two yeast strains, the cells of which contained xylose and Q-10 as the major ubiquinone, were isolated from a plant leaf collected in Taiwan. These yeasts were found to represent two new species of the genus Bullera in the Hymenomycetes. Identification was based on the sequence analysis of the 18S rDNA, the internal transcribed spacer (ITS) regions and the D1/D2 domain of 26S rDNA. The yeasts are named Bullera melastomae sp. nov. and Bullera formosana sp. nov. In the phylogenetic trees based on 18S rDNA and D1/D2 domain of 26S rDNA sequences, these two species constitute a cluster connected with Dioszegia cluster in the Cryptococcus luteolus lineage.
