Among ascomycetous yeasts that were isolated from several nature reserve areas in China, three anamorphic strains isolated from soil (QL 5-5T) and fruit (QL 21-2T and SN 15-1T) were revealed, by conventional characterization and molecular phylogenetic analysis based on internal transcribed spacer and large subunit (26S) rRNA gene D1/D2 region sequencing, to represent three novel species in the genus Candida. Candida qinlingensis sp. nov. (type strain, QL 5-5T=AS 2.2524T=CBS 9768T) was related closely to a teleomorphic species, Williopsis pratensis. The close relatives of Candida diospyri sp. nov. (type strain, QL 21-2T=AS 2.2525T=CBS 9769T) are Candida friedrichii and Candida membranifaciens. Candida asparagi sp. nov. (type strain, SN 15-1T=AS 2.2526T=CBS 9770T) forms a clade with Candida fructus.
从中国几个自然保护区分离得到的子囊菌酵母中，通过基于内转录间隔区和大亚基（26S）rRNA基因D1/D2区域测序的常规鉴定和分子系统发育分析，发现从土壤（QL 5-5T）和果实（QL 21-2T和SN 15-1T）中分离得到的三株无性型菌株代表念珠菌属的三个新物种。秦岭念珠菌（Candida qinlingensis）新种（模式菌株，QL 5-5T=AS 2.2524T=CBS 9768T）与有性型物种草地威克酵母（Williopsis pratensis）密切相关。柿念珠菌（Candida diospyri）新种（模式菌株，QL 21-2T=AS 2.2525T=CBS 9769T）的近缘种是费氏念珠菌（Candida friedrichii）和膜状念珠菌（Candida membranifaciens）。芦笋念珠菌（Candida asparagi）新种（模式菌株，SN 15-1T=AS 2.2526T=CBS 9770T）与果实念珠菌（Candida fructus）形成一个进化枝。
