Kodamaea neixiangensis f.a., sp. nov. and Kodamaea jinghongensis f.a., sp. nov., two yeast species isolated from rotting wood

Abstract

Seven strains representing two novel yeast species were isolated from rotting wood in Henan and Yunnan Provinces, PR China. The results of phylogenetic analysis based on the D1/D2 domains of the large subunit (LSU) rRNA gene revealed that these two species are members of the genus Kodamaea, although the formation of ascospores was not observed. Kodamaea neixiangensis f.a., sp. nov. (type strain NYNU 167139T=CICC 33170T=CBS 14699T) formed a clade with Candida kaohsiungensis and Candida hsintzibuensis, from which it differed by 10-16 substitutions in the D1/D2 domain. The ITS sequences of K. neixiangensis sp. nov. differed by 27 substitutions from those of the type strain of C. kaohsiungensis. The most closely related species with a validly published name to Kodamaea jinghongensis f.a., sp. nov. (type strain NYNU 167162T=CICC 33171T=CBS 14700T) was Candida fukazawae, but this differed by 14 substitutions in the D1/D2 domain and by 15 substitutions in the ITS region.
