Abstract

Yamadazyma is one of the largest genera in the family Debaryomycetaceae (Saccharomycetales, Saccharomycetes) with species mainly found in rotting wood, insects and their resulting frass, but also recovered from flowers, leaves, fruits, tree bark, mushrooms, sea water, minerals, and the atmosphere. In the present study, several strains obtained from rotting wood in Henan and Yunnan Provinces of China were isolated. Based on morphology and a molecular phylogeny of the rDNA internal transcribed spacer region (ITS) and the D1/D2 domain of the large subunit (LSU) rDNA, these strains were identified as three new species: Yamadazyma luoyangensis, Y. ovata and Y. paraaseri; and three previously described species, Y. insectorum, Y. akitaensis, and Y. olivae. The three new species are illustrated and their morphology and phylogenetic relationships with other Yamadazyma species are discussed. Our results indicate a high undiscovered diversity of Yamadazyma spp. inhabiting rotting wood in China.
