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.
