Bullera taiwanensis sp nov and Bullera formosensis sp nov, two new ballistoconidium-forming yeast species isolated from plant leaves in Taiwan.
Two strains of ballistoconidiogenous yeasts that contain xylose and form Q-10 ubiquinone were isolated from plant leaves collected in Taiwan and were found to represent two new species. The taxonomic properties of both coincide with the genus Bullera so they are described as Bullera taiwanensis sp. nov. and Bullera formosensis sp. nov. In a phylogenetic tree based on the nucleotide sequences of 18S ribosomal DNAs, these two species are distant from the clusters where the remaining members of the genus Bullera are located, i.e., Bullera taiwanensis is located in the Filobasidium lineage (Filobasidiales clade) and Bullera formosensis is located in the Cryptococcus humicola-Trichosporon lineage (Trichosporonales clade).
