Abstract
Species of the genus Sugiyamaella (Trichomonascaceae, Saccharomycetales), found in rotting wood in China, were investigated using morphology and the molecular phylogeny of a combined ITS and nrLSU dataset. Nine taxa were collected in China: two were new species (viz. Sugiyamaella chuxiong sp. nov. and S. yunanensis sp. nov. ) and seven were known species, S. americana , S. ayubii , S. novakii , S. paludigena , S. valenteae , S. valdiviana and S. xiaguanensis . The two new species are illustrated and their morphology and phylogenetic relationships with other Sugiyamaella species are discussed. Our results indicate a potentially great diversity of Sugiyamaella spp. inhabiting rotting wood in China just waiting to be discovered.
