Five new additions to the genus Spathaspora (Saccharomycetales, Debaryomycetaceae) from southwest China

Spathaspora is an important genus of d-xylose-fermenting yeasts that are poorly studied in China. During recent yeast collections in Yunnan Province in China, 13 isolates of Spathaspora were obtained from rotting wood and all represent undescribed taxa.

Descripción
Sumario:Spathaspora is an important genus of d-xylose-fermenting yeasts that are poorly studied in China. During recent yeast collections in Yunnan Province in China, 13 isolates of Spathaspora were obtained from rotting wood and all represent undescribed taxa. Based on morphological and phylogenetic analyses (ITS and nuc 28S), five new species are proposed: Spathaspora elongata, Sp. mengyangensis, Sp. jiuxiensis, Sp. parajiuxiensis and Sp. rosae. Our results indicate a high species diversity of Spathaspora waiting to be discovered in rotting wood from tropical and subtropical southwest China. In addition, the two Candida species, C. jeffriesii and C. materiae, which are members of the Spathaspora clade based on phylogeny, are transferred to Spathaspora as new combinations.
