Taxonomic study of polymorphic basidiomycetous fungi Sirobasidium and Sirotrema: Sirobasidium apiculatum sp. nov., Phaeotremella translucens comb. nov. and rediscovery of Sirobasidium japonicum in Japan.

Species in the genera Sirobasidium and Sirotrema (Tremellales, Tremellomycetes, Agaricomycotina, Basidiomycota) have been described based solely on the morphology of teleomorph, and many of them lack both isolates of anamorphic yeast state and nucleotide sequence data. Strains of Sirotrema translucens and Sirobasidium japonicum were established for the first time from basidiocarps collected in Japan. Also, an undescribed species in the genus Sirobasidium was isolated.

D-Fructose Assimilation and Fermentation by Yeasts Belonging to Saccharomycetes: Rediscovery of Universal Phenotypes and Elucidation of Fructophilic Behaviors in and .

The purpose of this study was to investigate the ability of ascomycetous yeasts to assimilate/ferment d-fructose. This ability of the vast majority of yeasts has long been neglected since the standardization of the methodology around 1950, wherein fructose was excluded from the standard set of physiological properties for characterizing yeast species, despite the ubiquitous presence of fructose in the natural environment. In this study, we examined 388 strains of yeast, mainly belonging to the Saccharomycetes (Saccharomycotina, Ascomycota), to determine whether they can assimilate/ferment d-fructose.

Revision of (, ) to include Sarea and Tromera.

The resinicolous fungi and () were taxonomically revised on the basis of morphological observations and phylogenetic analyses of the nucleotide sequences of the nSSU-LSU---mtSSU genes. The results of phylogenetic analyses show that and are grouped with members of . According to the results of phylogenetic analyses and their sexual and asexual morphs resemblance, is synonymized with .

Draft Genome Sequence of Novel sp. Strain JCM 33374, a Nectar Yeast Isolated from a Bumblebee.

Here, we report the draft genome sequence of sp. strain JCM 33374, a nectar yeast isolated from a bumblebee (). The genome of 20.

sp. nov., a new basidiomycetous yeast species isolated from a mangrove forest in Thailand.

Strains of yeast were isolated under a nitrogen-depleted culture condition from decaying tree bark (strain N-12.1) and from mangrove forest water (strain 1-7W.1) sampled at different locations within a mangrove forest site in Ranong province, Thailand.
