N2 - Among ballistoconidium-forming yeast strains isolated from various plant leaves collected from subtropical forests in eastern and central China, four strains forming cream to yellowish colored colonies were revealed to represent three novel Derxomyces species by conventional and molecular characterization. Phylogenetic analysis based on combined sequences of the internal transcribed spacer (ITS) and 26S rRNA gene D1/D2 domain showed that strains GT-753 and ZJJ-890(T) were conspecific and closely related to Derxomyces boninensis, Derxomyce mrakii and Derxomyce qinlingensis. Strain ZJJ-394(T) was basal to the branch formed by D. komagatae, D. pseudoschimicola and D. schimicola with strong bootstrap support. Strain GT-475(T) was closely related to D. linzhiensis. The strains differed significantly from their close relatives in D1/D2 and ITS sequences and in physiological criteria. The novel species are described as Derxomyces amylogenes sp. nov. (type strain ZJJ-890(T) =CGMCC 2.4407(T) =CBS 12233(T)), Derxomyces bambusicola sp. nov. (type strain GT-475(T) =CGMCC 2.4411(T) =CBS 12234(T)) and Derxomyces corylopsis sp. nov. (type strain ZJJ-394(T) =CGMCC 2.4409(T) =CBS 12259(T)).
