“…In the tree derived from the expanded LSU rRNA gene sequence dataset, two teleomorphic mycoparasites Trimorphomyces nebularis and Trimorphomyces sp. CBS 200.94 ( Takashima et al., 2003 , Kirschner and Chen, 2008 ) and three recently published Cryptococcus species were also located in this clade ( Fig. 5 D).…”

“…Yeasts of this genus are widespread eurybionts and are often found associated with plant material ( Fonseca and Inácio, 2006 , Fonseca et al., 2011 , Yurkov et al., 2015 ). A possible mycoparasitic nature has been suggested for these yeasts, which may have sexual trimorphomyces-like morphs ( Kirschner & Chen 2008 ). This genus currently contains eleven described species ( Table 1 ) and four additional sequences representing potential new species were obtained from public databases ( Fig.…”

“…Another described Trimorphomyces species, T. nebularis ( Kirschner & Chen 2008 ), is transferred to the genus Vishniacozyma gen. nov. Trimorphomyces papilionaceus forms zygoconidia from a single conidiogenous cell, differing from T. nebularis ( Vishniacozyma nebularis comb. nov.) which produces zygoconidia from two neighbouring conidiogenous cells ( Bandoni and Oberwinkler, 1983 , Kirschner and Chen, 2008 ). The genus Trimorphomyces currently contains two species ( Table 1 , Fig.…”

Families and genera assigned to Tremellomycetes have been mainly circumscribed by morphology and for the yeasts also by biochemical and physiological characteristics. This phenotype-based classification is largely in conflict with molecular phylogenetic analyses. Here a phylogenetic classification framework for the Tremellomycetes is proposed based on the results of phylogenetic analyses from a seven-genes dataset covering the majority of tremellomycetous yeasts and closely related filamentous taxa. Circumscriptions of the taxonomic units at the order, family and genus levels recognised were quantitatively assessed using the phylogenetic rank boundary optimisation (PRBO) and modified general mixed Yule coalescent (GMYC) tests. In addition, a comprehensive phylogenetic analysis on an expanded LSU rRNA (D1/D2 domains) gene sequence dataset covering as many as available teleomorphic and filamentous taxa within Tremellomycetes was performed to investigate the relationships between yeasts and filamentous taxa and to examine the stability of undersampled clades. Based on the results inferred from molecular data and morphological and physiochemical features, we propose an updated classification for the Tremellomycetes. We accept five orders, 17 families and 54 genera, including seven new families and 18 new genera. In addition, seven families and 17 genera are emended and one new species name and 185 new combinations are proposed. We propose to use the term pro tempore or pro tem. in abbreviation to indicate the species names that are temporarily maintained.

“…Currently, the genus Vishniacozyma contains the species Vishniacozyma carnescens, Vishniacozyma dimennae, Vishniacozyma ellesmerensis, Vishniacozyma foliicola, Vishniacozyma globispora, Vishniacozyma heimaeyensis, Vishniacozyma nebularis, Vishniacozyma penaeus, Vishniacozyma psychrotolerans, Vishniacozyma taibaiensis, Vishniacozyma tephrensis and Vishniacozyma victoriae [11,12]. The phylogenetic transfer of Trimorphomyces nebularis to he genus Vishniacozyma was based on the D1/D2 domain sequence as there is no other genetic data deposited in databases [11,13]. All species are morphologically indistinguishable [11], except V. nebularis, which, unlike the rest of the genus, has a sexual state [13].…”

Plants are important reservoirs of described and undescribed species of yeast. During a study of yeasts associated with bromeliads from the Northeast region of Brazil (collected in 2013–2017), analysis of the D1/D2 domain of the LSU rRNA and internal transcribed spacer (ITS) region identified eleven strains of yeasts as representing an unknown species of the genus Vishniacozyma. The species may have a diverse habitat in Brazil as a strain was collected from a flowering plant (Acanthaceae) in 1994. As a consequence, we propose Vishniacozyma alagoana sp. nov. as a member of the tremellomycetes yeasts (Agaricomycotina, Basidiomycota). Vishniacozyma alagoana sp. nov. was found in Atlantic Forest (a tropical rainforest) and the Caatinga (a seasonally dry tropical forest) associated with bromeliads in northeast and southeastern Brazil. The proposed novel species is related to Vishniacozyma taibaiensis and distinguished by eight nucleotide substitutions in the D1/D2 domain and seventeen in the ITS region. In addition, Vishniacozyma alagoana sp. nov. differs from V. taibaiensis by the ability to assimilate ribitol. The holotype is CBS 15966T.

Ovipoculum album, a new anamorph with gelatinous cupulate bulbilliferous conidiomata from China and with affinities to the Auriculariales (Basidiomycota)

An anamorphic fungus forming laterally attached, cupulate, gelatinous, hyaline to white conidiomata producing bulbils from clamped hyphae was collected on dead bamboo culms in southwestern China. Though the conidiomatal morphology is similar to that of Dacryoscyphus (anamorphic Dacrymycetales), microscopical and DNA sequence analysis revealed a phylogenetic relationship with members of the Auriculariales. The taxon is therefore described as new and separate from Dacryoscyphus. It is also distinct from other recognized bulbilliferous basidiomycetes. Two recently described anamorphic Dacrymyces species, D. pinacearum and D. subarcticus, were restudied and are transferred to Dacryoscyphus.
