Three apiculate yeast strains, EJ7M09T, GJ5M15 and GJ15M04, isolated from mushrooms in Taiwan were found to represent a novel species of the genus Kloeckera. The phylogenetically closest relative of this novel species is Hanseniaspora occidentalis, but the type strain of H. occidentalis differed by 4.6 % divergence (25 substitutions; 5 gaps) in the sequence of the D1/D2 domain of the large subunit rRNA gene. This difference clearly suggests that the three strains represent a distinct species. As none of the strains that were examined in this study produced ascospores or exhibited conjugation on common sporulation medium either alone or in a pairwise mixture, this species could be considered as an anamorphic member of the genus Hanseniaspora, and a novel species, Kloeckera taiwanica sp. nov., is proposed, with EJ7M09T ( = BCRC 23182T = CBS 11434T) as the type strain.

Five strains (RV5T, RV140, R31T, RS17 and RS28T) representing three novel anamorphic ascomycetous yeast species were isolated by membrane filtration from estuarine waters collected from a mangrove forest in Laem Son National Park, Ranong Province, Thailand, on different occasions. On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, sequence analysis of the D1/D2 domain of the large-subunit rRNA gene and the internal transcribed spacer region and phylogenetic analysis, three strains were found to represent two novel Candida species. Two strains (RV5T and RV140) represented a single novel species, for which the name Candida laemsonensis sp. nov. is proposed. The type strain is RV5T (=BCC 35154T =NBRC 105873T =CBS 11419T). Strain R31T was assigned to a novel species that was named Candida andamanensis sp. nov. (type strain R31T =BCC 25965T =NBRC 103862T =CBS 10859T). On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, sequence analysis of the D1/D2 domain of the large-subunit rRNA gene and phylogenetic analysis, strains RS17 and RS28T represented another novel species of Candida, for which the name Candida ranongensis sp. nov. is proposed. The type strain is RS28T (=BCC 25964T =NBRC 103861T =CBS 10861T).

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.

Five yeast strains (Ym24403, Ym24404, Ym24408, Ym24409 and Ym24410T) were isolated from different flowers of Erianthus rufipilus (Gramineae), a wild plant growing in the phosphorus-rich region in Yunnan Province, south-western China, and were found to be phenotypically and genetically divergent from currently recognized yeast species. Sequence analysis of the D1/D2 domain of the large subunit rRNA gene revealed that the five strains represented a novel species described as Starmerella jinningensis sp. nov. The type strain is Ym24410T ( = CBS 11864T  = CCTCC AY 2011002T). Phylogenetic analysis based on the D1/D2 region of the large subunit rRNA gene suggested that S. jinningensis sp. nov. is placed within the Starmerella clade.

Four strains of two novel xylose-utilizing yeast species were obtained from samples collected in Thailand from decaying corncobs (strains KU-Xs13T and KU-Xs18), a decaying grass (KU-Xs20) and estuarine water from a mangrove forest (WB15T). On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics and sequence analysis of the D1/D2 domain of the large subunit rRNA gene, the four strains were found to represent two novel species of the genus Candida in the Candida albicans/Lodderomyces elongisporus clade. Three strains (KU-Xs13T, KU-Xs18 and KU-Xs20) were assigned as a single novel species, which was named Candida saraburiensis sp. nov. The type strain is KU-Xs13T (=CBS 11696T=NBRC 106721T=BCC 39601T). Strain WB15T represented another novel species of the genus Candida that was named Candida prachuapensis sp. nov. The type strain is WB15T (=CBS 11024T=NBRC 104881T=BCC 29904T).

In the course of an on-going study aimed at cataloguing the natural yeast biodiversity found in Ecuador, two strains (CLQCA 13-025 and CLQCA 20-004T) were isolated from samples of cow manure and rotten wood collected in two separate provinces of the country (Orellana and Bolívar). These strains were found to represent a novel yeast species based on the sequences of their D1/D2 domain of the large-subunit (LSU) rRNA gene and their physiological characteristics. Phylogenetic analysis based on LSU D1/D2 sequences revealed this novel species to belong to the Metschnikowia clade and to be most closely related to Candida suratensis, a species recently discovered in a mangrove forest in Thailand. The species name of Candida ecuadorensis sp. nov. is proposed to accommodate these strains, with strain CLQCA 20-004T ( = CBS 12653T = NCYC 3782T) designated as the type strain.

Five yeast strains isolated from forest habitats in Hungary and Germany were characterized phenotypically and by sequencing of the D1/D2 domain of the large subunit rRNA gene and the ITS1-5.8S-ITS2 (ITS) region of the rRNA gene. The strains have identical D1/D2 domain and ITS region sequences. By sequence comparisons, Candida mycetangii and Candida maritima were identified as the closest relatives among the currently recognized yeast species. The DNA sequences of the investigated strains differ by 1.2 % (six substitutions) in the D1/D2 domain and by 3.5 % (12 substitutions and eight indels) in the ITS region from the type strain of C. mycetangii (CBS 8675T) while by 1.2 % (six substitutions and one indel) in the D1/D2 domain and by 7 % (32 substitutions and seven indels) in the ITS region from the type strain of C. maritima (CBS 5107T). Because the intraspecies heterogeneity seems to be very low and the distance to the most closely related species is above the commonly expected level for intraspecies variability Cyberlindnera sylvatica sp. nov. (holotype, CBS 16335T; isotype, NCAIM Y.02233T; MycoBank no., MB 835268) is proposed to accommodate the above-noted five yeast strains. Phenotypically the novel species can be distinguished from C. mycetangii and C. maritima by the formation of ascospores. Cyberlindnera sylvatica forms one or two hat-shaped ascospores per ascus on many different media as well as well-developed pseudohyphae and true hyphae. Additionally, we propose the transfer of three anamorphic members of the Cyberlindnera americana sub-clade to the genus Cyberlindnera as the following new taxonomic combinations Cyberlindnera maritima f.a., comb. nov., Cyberlindnera mycetangii f.a., comb. nov. and Cyberlindnera nakhonratchasimensis f.a., comb. nov.

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).

Twenty-four yeast strains were isolated from ephemeral flowers of Ipomoea spp. and Datura sp. and their associated insects in the Galápagos Archipelago, Ecuador, and from Ipomoea spp. and associated insects in the Cameron Highlands, Malaysia. Sequences of the D1/D2 domains of the large subunit rRNA gene indicated that these strains belong to a novel yeast species of the Kodamaea clade, although the formation of ascospores was not observed. The closest relative is Candida restingae. The human-mediated dispersion of this species by transpacific contacts in ancient times is suggested. The name Kodamaea transpacifica f.a., sp. nov. is proposed to accommodate these isolates. The type strain is CLQCA-24i-070T ( = CBS 12823T = NCYC 3852T); MycoBank number MB 803609.
