Two strains of a novel yeast species were isolated from insect frass and a flower in Thailand and Brazil, respectively. The strain from Thailand was isolated from insect frass collected in Than-Tong waterfall, Nong Khai Province, whereas the strain from Brazil was recovered from a flower of Ipomoea sp. collected on the banks of the Paraguai River in the state of Mato Grosso do Sul. The sequences of the D1/D2 domains of the large subunit of the rDNA of both strains were identical. This novel species belonged to the Metschnikowia clade and was related to Metschnikowia lunata. No signs of sporulation were observed for the two strains on various culture media. The novel species, Candida golubevii sp. nov., is proposed to accommodate these isolates. The type strain is BCC 8332T (=CBS 11362T=NBRC 105679T).

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.

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).

Two strains of a novel cactophilic yeast species were isolated from the columnar cactus Pilosocereus arrabidae in a sand dune ecosystem in Rio de Janeiro, Brazil. Phylogenetic analysis of sequences of the large subunit rRNA gene D1/D2 domains showed that the strains represent a sister species to Starmera caribaea, from which it differs by 21 nt substitutions and two indels. The novel species is heterothallic and the asci are deliquescent with the formation of two to four hat-shaped ascospores. The name Starmera pilosocereana sp. nov. is proposed for the species. The type strain is UFMG-CM-Y316T ( = CBS 13266T) and the allotype is UFMG-CM-Y346a ( = CBS 13265). The Mycobank number is MB 810683. In addition, Candida stellimalicola belonging to the Starmera clade, is reassigned to Starmera as a new combination.

In an investigation of the yeast biota involved in silage deterioration, a considerable number of strains belonging to Saccharomyces and related genera were isolated from aerobically deteriorating corn silage in Tochigi, Japan. Analysis of sequences of the internal transcribed spacer and the large-subunit rRNA gene D1/D2 domain and electrophoretic karyotyping indicated that two of the strains, NS 14T and NS 26, represent a novel species with close phylogenetic relationships to Kazachstania servazzii and Kazachstania unispora. It is proposed that the novel species be named Kazachstania aerobia sp. nov., with NS 14T (=AS 2.2384T=CBS 9918T) as the type strain.

The novel genus Holtermanniella is proposed here to accommodate four Cryptococcus species closely related to Holtermannia corniformis that are included in the Holtermannia clade (Basidiomycota, Agaricomycotina). Thus, four novel combinations are proposed: Holtermanniella nyarrowii comb. nov., Holtermanniella festucosa comb. nov., Holtermanniella mycelialis comb. nov. and Holtermanniella wattica comb. nov. In addition, a novel anamorphic yeast species was studied with 15 isolates obtained from different habitats around the world. Analysis of the sequences of the D1/D2 region of their large subunit rDNA showed that the novel species is placed phylogenetically within the Holtermannia clade of the Tremellomycetes (Agaricomycotina, Basidiomycota). PCR fingerprinting and sequencing of ITS1–5.8S–ITS2 showed genetic intraspecific variability among the strains: three groups were formed, which did not correlate with geographical origin or substrate. This novel species, designated the type species of Holtermanniella gen. nov., is described as Holtermanniella takashimae sp. nov.; the type strain is CBS 11174T (=HB 982T =DBVPG 8012T). The order Holtermanniales ord. nov. is proposed here to include Holtermannia (the type genus) and Holtermanniella.

Two independent surveys of yeasts associated with different bromeliads in different Brazilian regions led to the proposal of a novel yeast species, Bullera vrieseae sp. nov., belonging to the Tremellales clade (Agaricomycotina, Basidiomycota). Analysis of the sequences in the internal transcribed spacer (ITS) region and D1/D2 domain of the LSU rRNA gene suggested affinity to a phylogenetic lineage that includes Bullera miyagiana and Bullera sakaeratica. Six isolates of the novel species were obtained from different bromeliads and regions in Brazil. Sequence analysis of the D1/D2 domains of the large subunit of the rRNA gene showed that the novel species differs from B. miyagiana and B. sakaeratica by 85 and 64 nt substitutions, respectively and by more than 75 nt substitutions in the ITS region. Phenotypically, Bullera vrieseae sp. nov. can be distinguished from both species based on the assimilation of meso-erythritol, which was negative for B. vrieseae sp. nov. but positive for the others, assimilation of d-glucosamine, which was positive for B. vrieseae sp. nov. but negative for B. miyagiana and of l-sorbose, which was negative for B. vrieseae sp. nov. but positive for B. sakaeratica. The novel species Bullera vrieseae sp. nov. is proposed to accommodate these isolates. The type strain of Bullera vrieseae sp. nov. is UFMG-CM-Y379T (BRO443T; ex-type CBS 13870T).

Cultures of a novel nutritionally specialized, fermentative yeast species were isolated from 34 water tanks of five bromeliad species, two mangrove sediment samples and one swamp water sample in Rio de Janeiro, Brazil. Sequence analysis of the D1/D2 domains of the large subunit of the rRNA gene showed that the novel species belongs to the genus Kazachstania. The novel species differs from Kazachstania martiniae by 11 substitutions and 2 gaps in the sequence of the domains D1/D2 of the LSU rRNA gene. The name Kazachstania bromeliacearum sp. nov. is proposed for the novel species. The type strain is IMUFRJ 51496T ( = CBS 7996T  = DBVPG 6864T  = UFMG BR-174T).

Six strains representing a novel yeast species belonging to the genus Saturnispora were isolated from two species of the Drosophila fasciola subgroup (Drosophila repleta group) in an Atlantic rainforest site in Rio de Janeiro State, Brazil. Four strains were isolated from crops and one from external parts of Drosophila cardinae. The other strain was isolated from external parts of Drosophila fascioloides. Analysis of the D1/D2 large-subunit rDNA sequences indicated that the novel species is closely related to Saturnispora dispora. The name Saturnispora hagleri sp. nov. is proposed to accommodate these strains. The type strain is UFMG-55T (=CBS 10007T=NRRL Y-27828T).

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).
