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).

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.

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.

Two yeast strains were isolated from a bumblebee and bumblebee honey. The strains were almost identical in their D1/D2 domain of the large-subunit rDNA and their physiological abilities. In both respects the strains resembled Wickerhamiella domercqiae. On the basis of these data, it is proposed that the strains represent a novel species with the name Candida bombiphila sp. nov. The type strain is CBS 9712T (=NRRL Y-27640T=MH268T).

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).

Six strains of a novel yeast species were isolated from Nothofagus species trees in native forests in Patagonia, Argentina. The strains were isolated from bark, fluxes and the ectomycorrhizospheric soil fraction of Nothofagus antarctica, Nothofagus nervosa and Nothofagus pumilio. Analysis of the D1/D2 large-subunit rDNA sequences indicated that the novel species belonged to the genus Lachancea and is closely related to Lachancea meyersii. The name Lachancea nothofagi sp. nov. is proposed to accommodate these strains. The type strain is UWOPS 99-807.3T (=CBS 11611T=NRRL Y-48670T).

Two strains (S-34T and S-35) of a novel ascomycetous yeast species belonging to the genus Kazachstania were isolated from soil from a mixed deciduous forest in Amphoe Wang Nam Khiao, Nakhon Ratchasima Province, Thailand. The D1/D2 domains of the large-subunit rDNA sequences of the two strains were identical and also indicated a close relationship with respect to Kazachstania aquatica, Kazachstania unispora, Kazachstania aerobia, Kazachstania servazzii and Kazachstania solicola. The most closely related species, K. aquatica, has 14 nucleotide substitutions and three gaps in 566 nt. The phenotypic characteristics of the two strains were typical of those of members of the genus Kazachstania. These characteristics include the formation of a single globose ascospore in an unconjugated and persistent ascus, multilateral budding, the absence of arthrospores and ballistospores, the fermentation of glucose, the inability to assimilate nitrate, negative diazonium blue B and urease reactions, and the presence of ubiquinone Q-6. The novel strains can be distinguished from K. aquatica on the basis of a number of phenotypic characteristics and represent a novel species in the genus Kazachstania, for which the name Kazachstania siamensis sp. nov. is proposed. The type strain is S-34T (=CBS 10361T=NBRC 101968T=BCC 21230T).

The genus Blastobotrys, which now includes species previously assigned to the synonymous genera Arxula and Sympodiomyces, represents the anamorph of the ascosporogenous genus Trichomonascus. Six novel species are proposed for assignment to Blastobotrys. They were detected from their unique nucleotide sequences in large-subunit rDNA, ITS1–5.8S–ITS2 rDNA, mitochondrial small-subunit rDNA and the cytochrome oxidase II gene. The proposed novel species are Blastobotrys americana sp. nov. (type strain NRRL Y-6844T=CBS 10337T; substrate unknown; Kansas, USA), Blastobotrys illinoisensis sp. nov. (type strain NRRL YB-1343T=CBS 10339T; from forest debris; Illinois, USA), Blastobotrys malaysiensis sp. nov. (type strain NRRL Y-6417T=CBS 10336T; from soil; Malaysia), Blastobotrys muscicola sp. nov. (type strain NRRL Y-7993T=CBS 10338T; from moss; Louisiana, USA), Blastobotrys peoriensis sp. nov. (type strain NRRL YB-2290T=CBS 10340T; from a fungus; Peoria, IL, USA) and Blastobotrys raffinosifermentans sp. nov. (type strain NRRL Y-27150T=CBS 6800T; substrate unknown).

Two strains of a novel yeast species were isolated from ectomycorrhizal Nothofagus pumilio rhizospheric soil in a native forest of Patagonia, Argentina. Analysis of the D1/D2 large-subunit rRNA gene sequences indicated that the novel species belongs to the recently described genus Lindnera. The name Lindnera rhizosphaerae sp. nov. is proposed to accommodate these isolates, and the type strain is CRUB 1796T ( = CBS 11400T  = JCM 16499T).

During an investigation of yeast biota in the rhizosphere of lentisk in Sardinian semi-arid areas, a strain was isolated that could not be assigned to any known species. The sequence of the D1/D2 domain of the large subunit rDNA gene revealed that the strain belonged to the genus Kazachstania and was phylogenetically related to a clade including Kazachstania aerobia, Kazachstania servazzii, Kazachstania solicola and Kazachstania unispora. The novel isolate differed from members of this clade in its ability to assimilate d-glucono-1,5-lactone and its very weak fermentation of glucose and sucrose; its assimilation profile was unique within the genus Kazachstania. Monosporal colonies were able to sporulate, indicating that the species is homothallic. It is proposed that the isolate represents a novel species, Kazachstania ichnusensis sp. nov., with LCF 1675T ( = CBS 11859T) as type strain.

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.
