Background: Independent surveys across the globe led to the proposal of a new basidiomycetous yeast genus within the Bulleromyces clade of the Tremellales, Bandoniozyma gen. nov., with seven new species. Methodology/Principal Findings: The species were characterized by multiple methods, including the analysis of D1/D2 and ITS nucleotide sequences, and morphological and physiological/biochemical traits. Most species can ferment glucose, which is an unusual trait among basidiomycetous yeasts. Conclusions/Significance: In this study we propose the new yeast genus Bandoniozyma, with seven species Bandoniozyma noutii sp. nov. (type species of genus; CBS 8364T = DBVPG 4489T), Bandoniozyma aquatica sp. nov. (UFMG-DH4.20T = CBS 12527T = ATCC MYA-4876T), Bandoniozyma complexa sp. nov. (CBS 11570T = ATCC MYA-4603T = MA28aT), Bandoniozyma fermentans sp. nov. (CBS 12399T = NU7M71T = BCRC 23267T), Bandoniozyma glucofermentans sp. nov. (CBS 10381T = NRRL Y-48076T = ATCC MYA-4760T = BG 02-7-15-015A-1-1T), Bandoniozyma tunnelae sp. nov. (CBS 8024T = DBVPG 7000T), and Bandoniozyma visegradensis sp. nov. (CBS 12505T = NRRL Y-48783T = NCAIM Y.01952T). © 2012 Valente et al.

A marine xylarialean fungus, isolated from roots of Rhizophora (mangrove) in Australia, displays morphology of eight ellipsoidal dark brown asco-spores in a cylindrical ascus having a refractive apical apparatus. Each ascospore has a longitudinal germ slit. The fungus grew very slowly and produced dark brown water-soluble pigment(s) on various media. It developed unique, column-shaped, indeterminate synnemata on which needle-shaped conidia were produced. The sexual stage of this fungus was not observed under the laboratory conditions tested. Molecular phylogenetic analyses of the combined sequences of nuclear ribosomal RNA genes and their internal transcribed spacers placed it at a basal position in the clade of Diatrypaceae of the Xylariales with comparatively high statistical support. However the morphological features and phylogenetic position of this organism do not closely resemble any known fungal taxa. Therefore this fungus is proposed to be a representative of a novel taxon and described as Diatrypasimilis australiensis gen. et sp. nov. © 2010 by The Mycological Society of America.

Seven yeast strains were isolated from the body surface and galleries of Xyloterinus politus, the ambrosia beetle that attacks black oak trees. Based on rDNA sequence comparisons and other taxonomic characteristics, five of the strains were identified as members of the species Saccharomycopsis microspora, Wickerhamomyces hampshirensis and Candida mycetangii, which have been reported previously as being associated with insects. The remaining two yeast strains were proposed as representatives of two novel species, Candida xyloterini sp. nov. (type strain ATCC 62898(T)=CBS 11547(T)) and Candida palmyrensis sp. nov. (type strain ATCC 62899(T)=CBS 11546(T)). C. xyloterini sp. nov. is a close sister taxon to Ogataea dorogensis and assimilates methanol as a sole carbon source but lacks ascospores. On the other hand, C. palmyrensis sp. nov. is phylogenetically distinct from any other ambrosia yeast reported so far. The species was placed near Candida sophiae-reginae and Candida beechii based on DNA sequence analyses, but neither of these were close sister taxa to C. palmyrensis sp. nov.
