Candida golubevii sp nov., an asexual yeast related to Metschnikowia lunata

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 8332(T) (= CBS 11362(T) = NBRC 105679(T)).Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Synonymy of the yeast genera Moniliella and Trichosporonoides and proposal of Moniliella fonsecae sp. nov. and five new species combinations

Analyses of nucleotide sequences from the D1/D2 domains of the large-subunit rDNA and phenotypic characteristics showed that the genera Moniliella and Trichosporonoides are members of a single, monophyletic clade that would be best represented by a single anamorphic genus. On the basis of taxonomic priority, we propose the transfer of the five species of the genus Trichosporonoides to the genus Moniliella. The description of the genus Moniliella is emended and the following new combinations are proposed: Moniliella madida comb. nov., Moniliella megachiliensis comb. nov., Moniliella nigrescens comb. nov., Moniliella oedocephalis comb. nov. and Moniliella spathulata comb. nov. In addition, ten strains representing a novel yeast species belonging to the Moniliella clade were isolated from flowers in Thailand, Cuba and Brazil. Analysis of the internal transcribed spacer and D1/D2 large-subunit rDNA sequences indicated that the isolates represent a single species that was distinct from other species of the Moniliella clade. The name Moniliella fonsecae sp. nov. is proposed to accommodate these strains. The type strain is BCC 7726(T) (=CBS 10551(T))
