“…In a study of yeasts from wood-boring insects, we isolated a large number of yeasts mainly from the digestive tract of beetles as well as from related substrates, including rotted wood, frass and galleries [13], [14]. The majority of the yeast belonged to several major clades in the Saccharomycotina; some of these species have been identified as novel species in earlier papers [13]–[16].…”

Four strains of a novel ascomycetous yeast species were recovered from the frass of wood-boring beetles collected from the Baotianman Nature Reserve and the Laojieling Nature Reserve in Henan Province, China. This species produced unconjugated and deliquescent asci with hemispheroid or helmet-shaped ascospores. Analysis of gene sequences for the D1/D2 domain of the large subunit (LSU) rRNA, as well as analysis of concatenated gene sequences for the nearly complete small subunit (SSU) rRNA and D1/D2 domain of the large subunit (LSU) rRNA placed the novel species in a small clade including only one recognised species, Candida insectamans, in the family Debaryomycetaceae (Saccharomycotina, Ascomycota). DNA sequence analyses demonstrated that the novel species was distinct from all currently recognised teleomorphic yeast genus. The name Hemisphaericaspora nanyangensis gen nov., sp. nov. is proposed to accommodate the novel genus and species. The new genus can be distinguished from closely related teleomorphic genera Lodderomyces and Spathaspora through sequence comparison and ascospore morphology. The ex-type strain of H. nanyangensis is CBS 13020T ( = CICC 33021 = NYNU 13717). Furthermore, based on phenotypic and genotypic characteristics, C. insectamans is transferred to the newly described genus as Hemisphaericaspora insectamans comb. nov., in accordance with the changes in the International Code of Nomenclature for algae, fungi and plants.

“…Recently, Q. cyanescens (de Beer et al, 2006) and Q. coyrecup (Paap et al, 2008) have been also been described as plant pathogens. The genus Sympodiomycopsis was proposed by Sugiyama et al (1991) and, at the time of writing, includes three described species: S. paphiopedili (Sugiyama et al, 1991), S. kandeliae (Wei et al, 2011) and S. yantaiensis (Chen et al, 2013). The genus Jaminaea comprises J. angkorensis (Sipiczki & Kajdacsi, 2009) and J. lanaiensis (Wei et al, 2011).…”

“…The genus Sympodiomycopsis, that is sister to Jaminaea, appears to be associated with flowers (Sugiyama et al, 1991;Wei et al, 2011) and insects. The recent description of S. yantaiensis (Chen et al, 2013) showed that the presence of these yeasts in insect frass is probably due to the feeding activities of these insects on flowers. It has been reported that several insects (e.g.…”

During a survey of yeasts vectored by migratory birds in the Mediterranean basin, isolations from the cloacae of members of the order Passeriformes collected in Ustica (Italy) were performed. Based on phylogenetic analysis of the D1/D2 domain of the 26S rRNA gene and the internal transcribed spacer ITS1-5.8S rRNA gene-ITS2 region, five yeast isolates clustered in a new lineage within the Microstromatales clade. The DNA sequences of these isolates differed from those of their closest relatives, Jaminaea angkorensis and Jaminaea lanaiensis, by 20 and 25 nt substitutions in the D1/D2 domain and 119 and 131 nt substitutions in the complete ITS region, respectively. In addition, the five isolates showed phenotypic characteristics not observed in their closest relatives, such as the ability to grow at 44 8C and at pH 2.5, which suggests a possible adaptation to the bird gastrointestinal tract. On the basis of the isolation source, phenotypic features and molecular strain typing carried out with randomly amplified polymorphic DNA (RAPD)-PCR and mini-satellite-primed (MSP)-PCR analysis, the five isolates were characterized as five distinct strains of a novel species formally described as Jaminaea phylloscopi sp. nov., with 551B6T (5PYCC 6783 T 5CBS 14087 T ) as the type strain. The Mycobank accession number is MB811984.The Microstromatales represent an order that contains several teleomorphic and anamorphic genera. Among them, the genera Quambalaria and Sympodiomycopsis include the largest number of species, with five and three taxa, respectively, whereas the genus Jaminaea, the latest to be described (Sipiczki & Kajdacsi, 2009) (1991) and, at the time of writing, includes three described species: S. paphiopedili (Sugiyama et al., 1991), S. kandeliae (Wei et al., 2011) and S. yantaiensis (Chen et al., 2013). The genus Jaminaea comprises J. angkorensis (Sipiczki & Kajdacsi, 2009) and J. lanaiensis (Wei et al., 2011). This last species was originally described as Sympodiomycopsis lanaiensis by Mahdi et al. (2008).Recent studies have been focused on the diversity and ecology of ascomycetous yeasts carried by migratory birds (Cafarchia et al., 2006a; Cafarchia et al., 2006b;Francesca et al., 2010Francesca et al., , 2012 During an investigation of fungal diversity associated with cloacae of migratory birds in Ustica, several species of filamentous fungi were isolated and characterized (Alfonzo et al., 2013). Among them, five phenotypically similar isolates were preliminarily classified as basidiomycetous yeasts and stored for further investigation. In the present study, we show that these isolates represent five distinct strains of a novel species of the order Microstromatales.Birds were sampled during the migration from subSaharan areas to Europe in Ustica (388 429 N 138 109 480 E; sample date: 2-4 May 2009) (Alfonzo et al., 2013), an island north of Sicily (Italy) that represents one of the most important stop-over sites in the Mediterranean basin .

Two strains representing Wickerhamiella allomyrinae f.a., sp. nov. were isolated from the gut of Allomyrina dichotoma (Coleoptera: Scarabeidae) collected from the Baotianman National Nature Reserve, Nanyan, Henan Province, China. Sequence analyses of the D1/D2 domains of the LSU rRNA gene revealed that this novel species was located in the Wickerhamiella clade (Saccharomycetes, Saccharomycetales), with three described species of the genus Candida, namely Candida musiphila, Candida spandovensis and Candida sergipensis, as the most closely related species. The novel species differed from these three species by 9.3–9.8 % sequence divergence (35–45 nt substitutions) in the D1/D2 sequences. The species could also be distinguished from the closely related species, C. musiphila, C. spandovensis and C. sergipensis, by growth on vitamin-free medium and at 37 °C. The type strain is Wickerhamiella allomyrinae sp. nov. NYNU 13920T ( = CICC 33031T = CBS 13167T).
