Several independent surveys of yeasts associated with different plant materials and soil led to the proposal of a novel yeast species belonging to the Tremellales clade (Agaricomycotina, Basidiomycota). Analysis of the sequences of the D1/D2 domains and internal transcribed spacer region of the large subunit of the rRNA gene suggested affinity to a phylogenetic lineage that includes Hannaella coprosmaensis, Hannaella oryzae and Hannaella sinensis. Thirty-two isolates were obtained from different sources, including bromeliads, nectar of Heliconia psittacorum (Heliconiaceae), flowers of Pimenta dioica (Myrtaceae), roots and leaves of sugar cane (Saccharum spp.) in Brazil, leaves of Cratoxylum maingayi, Arundinaria pusilla and Vitis vinifera in Thailand, soil samples in Taiwan, and prairie soil in the USA. Sequence analysis of the D1/D2 domains of the large subunit of the rRNA gene showed that the novel species differs from Hannaella coprosmaensis and Hannaella oryzae by 36 and 46 nt substitutions, respectively. A novel species is suggested to accommodate these isolates, for which the name Hannaella pagnoccae sp. nov. is proposed. The type strain is BI118T ( = CBS 11142T = ATCC MYA-4530T).

Nine strains of a novel yeast species were isolated from rotting wood, tree bark, ant nests or living as endophytes in leaves of Vellozia gigantea. Analysis of the sequences of the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit rRNA gene showed that this species was related to Candida insectorum in the Yamadazyma clade. The novel species differed from closely related species by 10 and 11 substitutions in the ITS region and the D1/D2 domains of the large subunit of the rRNA gene, respectively. The species is heterothallic and forms asci with one to two hat-shaped ascospores. The name Yamadazyma riverae sp. nov. is proposed for the novel species. The type strain is UFMG-CM-Y444T ( = CBS 14121T) and the allotype strain is TT12 ( = CBS 14098 = UFMG-CM-Y577). The Mycobank number is MB 813221.

Waste Deposit

Four strains of a novel yeast species were isolated from laboratory nests of the leaf-cutting ant Atta sexdens in Brazil. Three strains were found in older sponges and one was in a waste deposit in the ant nests. Sequencing of the D1/D2 region of the large-subunit rRNA gene showed that the novel species, named Sympodiomyces attinorum sp. nov., is phylogenetically related to Sympodiomyces parvus. Unlike Sympodiomyces parvus, Sympodiomyces attinorum can ferment glucose, assimilate methyl α-d-glucoside, salicin and citrate, and grow at 37 °C, thus enabling these two species to be distinguished. Differentiation from other related species is possible on the basis of other growth characteristics. The type strain of Sympodiomyces attinorum is UNESP-S156T (=CBS 9734T=NRRL Y-27639T).

Mango Leaves

Five strains of a novel methanol-assimilating yeast species were isolated from mango (Mangifera indica) leaves collected at the campus of the Federal University of Minas Gerais in Brazil. The sequences of the internal transcribed spacer (ITS) region and the D1/D2 domains of the large subunit of the rRNA gene showed that this species belongs to the Ogataea clade and is related to O. allantospora, O. chonburiensis, O. dorogensis, O. kodamae, O. paradorogensis and Candida xyloterini (Ogataea clade). The novel species differs in the D1/D2 domains of the large subunit of the rRNA gene by 12 to 40 substitutions from these Ogataea species. The name Ogataea mangiferae sp. nov. is proposed for this novel species. The type strain of Ogataea mangiferae sp. nov. is UFMG-CM-Y253T ( = CBS 13492T). The Mycobank number is MB 811646.

Nine methanol-assimilating yeast strains isolated from olive oil sediments in Slovenia, extra virgin olive oil from Italy and rotten wood collected in Hungary were found to form three genetically separated groups, distinct from the currently recognized yeast species. Sequence analysis from genes of the small subunit (SSU) rRNA, internal transcribed spacer region/5.8S rRNA, large subunit (LSU) rRNA D1/D2 domains and translational elongation factor-1α (EF-1α) revealed that the three closely related groups represent three different undescribed yeast species. Sequence analysis of the LSU rRNA gene D1/D2 domains placed the novel species in the Ogataea clade. The three novel species are designated as Ogataea kolombanensis sp. nov. (type strain: ZIM 2322T = CBS 12778T = NRRL Y-63657T), Ogataea histrianica sp. nov. (type strain: ZIM 2463T = CBS 12779T = NRRL Y-63658T) and Ogataea deakii sp. nov. (type strain: NCAIM Y.01896T = CBS 12735T = NRRL Y-63656T).

Five strains of a novel yeast species were isolated from rotting wood samples collected in an Amazonian forest site in the state of Roraima, northern Brazil. The sequences of the D1/D2 domains of the large subunit of the rRNA gene showed that this species belongs to the Scheffersomyces clade and is related to Candida coipomoensis, Candida lignicola and Candida queiroziae. The novel species Candida amazonensis sp. nov. is proposed to accommodate these isolates. The type strain of C. amazonensis sp. nov. is UFMG-HMD-26.3T ( = CBS 12363T = NRRL Y-48762T).

Six strains of a novel yeast species were isolated from tree bark collected in the Atlantic Forest and the Amazon Rainforest in Brazil. Analyses of the sequences of D1/D2 domains of the large subunit rRNA gene showed that the strains belong to a species in the genus Zygotorulaspora. The species differed by 5.54 % sequence divergence (25 substitutions and five indels out of 542 bp) in the D1/D2 sequences from Zygotorulaspora mrakii, its closest relative. The ITS sequence of the type strain of the novel species differs by 27–69 nucleotide substitutions/indels from the other Zygotorulaspora species. The novel species is able to grow on trehalose, maltose, l-sorbose, inulin and at 37 °C, which are negative in Z. mrakii. The name Zygotorulaspora cariocana sp. nov. is proposed. The holotype of Z. cariocana sp. nov. is CBS 16118T. The MycoBank number is MB 833702.

Two isolates of a novel yeast species were obtained from water tanks (phytotelmata) of the bromeliad Vriesea minarum collected in a tableland (‘campo rupestre’) ecosystem in Brazil. The sequences of the D1/D2 domains of the large-subunit rRNA gene showed that this species is related to Kazachstania exigua and others, from which it differs by 8–10 nucleotide substitutions. The novel species Kazachstania rupicola sp. nov. is proposed to accommodate these isolates. The type strain is UFMG-BRO-80T ( = CBS 12684T  = CBMAI 1466T).

A novel yeast species was found repeatedly and in high cell densities in underground-nesting stingless bees of the species Melipona quinquefasciata and their provisions in northern Minas Gerais (Brazil). One additional strain was isolated from bee-collected pollen in Cuba. Phylogenetic analyses based on rRNA gene sequences (D1/D2 large subunit gene and internal transcribed spacer) indicated that the novel species belongs to the Starmerella clade and is most closely related to Candida (iter. nom. Starmerella) apicola. Growth reactions on carbon and nitrogen sources were typical of those observed in related species of the Starmerella clade. PCR-fingerprinting with mini- and microsatellite specific primers allowed the distinction of the novel species from Candida apicola, Candida bombi and a yet undescribed species represented by strain CBS 4353. On the basis of phylogenetic relationships, the novel species is assigned to the genus Starmerella despite the failure to observe sexual reproduction after extensive mating tests. We propose the name Starmerella neotropicalis f. a., sp. nov. (Mycobank MB 804285) and designate UFMG PST 09T ( = MUCL 53320T = CBS 12811T) as the type strain.
