Recent rDNA sequencing of 25 isolates from a previous study, during which limonene-utilizing yeasts were isolated from monoterpene-rich environments by using 1,4-disubstituted cyclohexanes as sole carbon sources, led to the identification of four hitherto unknown Rhodotorula species. Analyses of the 26S rDNA D1/D2 region as well as the internal transcribed spacer (ITS) domain indicated that two isolates (CBS 8499T and CBS 10736) were identical and were closely related to Rhodotorula cycloclastica, a previously described limonene-utilizing yeast. These novel isolates differed from known yeast species and could be distinguished from R. cycloclastica by standard physiological tests. The other three isolates represent three novel Rhodotorula species, closely related to Sporobolomyces magnisporus. These three species could also be distinguished from other Rhodotorula species by standard physiological tests. Based on these results, we suggest that the new isolates represent novel species, for which the names Rhodotorula eucalyptica sp. nov. (type strain CBS 8499T  = NRRL Y-48408T), Rhodotorula pini sp. nov. (type strain CBS 10735T  = NRRL Y-48410T), Rhodotorula bloemfonteinensis sp. nov. (type strain CBS 8598T  = NRRL Y-48407T) and Rhodotorula orientis sp. nov. (type strain CBS 8594T  = NRRL Y-48719T) are proposed. R. eucalyptica and R. pini can also utilize limonene.

Five yeast strains belonging to the genus Cryptococcus Vuillemin were isolated from steppe plants and turf collected in the Prioksko-terrasny biosphere reserve (Moscow region, Russia). Sequence analyses of the D1/D2 domains of the 26S rDNA and of the internal transcribed spacer region revealed that these yeast strains and strain CBS 8016 have almost identical sequences and belong to the Holtermannia clade of the Tremellomycetidae (Basidiomycota, Hymenomycetes). A novel species named Cryptococcus festucosus (type strain VKM Y-2930) is proposed to accommodate these strains. Physiological characteristics and mycocin sensitivity patterns distinguishing Cryptococcus festucosus from the other species of this clade are presented.Key words: mycocin sensitivity, rDNA sequencing, Cryptococcus, Holtermannia.

Five isolates of a novel species of the yeast genus Malassezia were isolated from animals in Japan and Brazil. Phylogenetic trees based on the D1/D2 domains of the large-subunit (26S) rDNA sequences and nucleotide sequences of the internal transcribed spacer 1 region showed that the isolates were conspecific and belonged to the genus Malassezia. They were related closely to Malassezia dermatis and Malassezia sympodialis, but were clearly distinct from these two species and the other six species of Malassezia that have been reported, indicating that they should be classified as a novel species, Malassezia nana sp. nov. Morphologically and physiologically, M. nana resembles M. dermatis and M. sympodialis, but can be distinguished from these species by its inability to use Cremophor EL (Sigma) as the sole lipid source and to hydrolyse aesculin. The type strain of M. nana is NUSV 1003T (=CBS 9557T=JCM 12085T).

During a study of newly isolated yeast strains utilizing d-xylose as sole carbon source, eight strains, isolated from decayed wood, were found to represent two novel anamorphic, ascomycetous yeast species based on sequence analysis of the 26S rDNA D1/D2 domain and internal transcribed spacer region, and phenotypic characterization. The names Candida laoshanensis sp. nov. (type strain MLRW 6-2T=AS 2.4030T=CBS 11389T) and Candida qingdaonensis sp. nov. (type strain MLRW 7-1T=AS 2.4031T=CBS 11390T) are proposed for these two novel species; the closest relatives of the two novel species are Candida pomicola and Candida marilandica, respectively.

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).

A basidiomycetous yeast, strain CRUB 1032T, which formed salmon-pink colonies, was isolated from glacial meltwater in Patagonia, Argentina. Morphological, physiological and biochemical characterization indicated that this strain belonged to the genus Rhodotorula. Molecular taxonomic analysis based on the 26S rDNA D1/D2 domain and internal transcribed spacer region sequences showed that strain CRUB 1032T represents an undescribed yeast species, for which the name Rhodotorula meli sp. nov. is proposed (type strain is CRUB 1032T=CBS 10797T=JCM 15319T). Phylogenetic analysis showed that Rhodotorula lamellibrachii was the closest known species, which, together with R. meli, formed a separate cluster related to the Sakaguchia clade within the Cystobasidiomycetes. Additional Patagonian yeast isolates of the class Cystobasidiomycetes are also investigated in the present work.

Three novel species are described as Rhodotorula rosulata sp. nov. (type strain VKM Y-2962T =CBS 10977T), Rhodotorula silvestris sp. nov. (type strain VKM Y-2971T =CBS 11420T) and Rhodotorula straminea sp. nov. (type strain VKM Y-2964T =CBS 10976T) based on the study of eight isolates from needle litter. The new species, phylogenetically located within the Microbotryomycetes, are related to glucuronate-assimilating species of the genus Rhodotorula. Sequencing of the D1/D2 domains of the LSU rDNA gene and the internal transcribed spacer (ITS) region, as well as physiological characterization, revealed their distinct taxonomic positions.

Eight yeast strains were isolated from jujube fruit surfaces collected in Shanxi and Shandong Provinces, China. All eight strains produced needle-shaped ascospores under suitable conditions. Three separate groups, representing three novel species in the genus Metschnikowia, were recognized by sequence comparisons of the 26S rDNA D1/D2 domain and internal transcribed spacer (ITS) region. The names Metschnikowia sinensis sp. nov. (type strain XY103T=AS 2.3110T=CBS 10357T), Metschnikowia zizyphicola sp. nov. (type strain XY201T=AS 2.3111T=CBS 10358T) and Metschnikowia shanxiensis sp. nov. (type strain XY801T=AS 2.3112T=CBS 10359T) are proposed for the three novel species. Phylogenetic analysis of the 26S rDNA D1/D2 domain sequence showed that these three novel species are clustered in a clade together with the previously described species Metschnikowia fructicola, Metschnikowia andauensis, Metschnikowia pulcherrima and Metschnikowia chrysoperlae.

Five yeast strains isolated from plant leaves collected in south-east Tibet formed cream to brownish colonies and produced asymmetrical ballistoconidia and CoQ-9 as the major ubiquinone. Sequence analysis of the 26S rRNA D1/D2 domain and the internal transcribed spacer region indicated that these strains represented two novel species of the genus Bensingtonia. The names Bensingtonia rectispora sp. nov. (type strain XZ 4C5T = CGMCC 2.02635T = CBS 10710T) and Bensingtonia bomiensis sp. nov. (type strain XZ 33D1T = CGMCC 2.02670T = CBS 10713T) are proposed for the two novel species, which are phylogenetically closely related to Bensingtonia naganoensis, Bensingtonia pseudonaganoensis and the type species of the genus, Bensingtonia ciliata.

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).

Taxonomic Characterization

Among yeasts isolated from plant leaves collected in different regions of China that form whitish or yellowish colonies and symmetrical ballistoconidia, four strains were shown to represent three novel Bullera species by conventional and molecular taxonomic characterization. The novel species are described as Bullera cylindrica sp. nov. (type strain CB 169T=AS 2.2308T=CBS 9744T), Bullera hubeiensis sp. nov. (type strain HX 19.3T=AS 2.2466T=CBS 9747T) and Bullera nakasei sp. nov. (type strain HX 15.5T=AS 2.2435T=CBS 9746T). These three species, and another eight previously described Bullera species represented by Bullera mrakii, formed a strongly supported distinct clade among the hymenomycetous yeasts in each of the phylogenetic trees drawn from the 26S rDNA D1/D2 domain and the internal transcribed spacer region sequences.
