In the course of a study on yeast diversity in Japan and Thailand, we isolated two yeast strains with bipolar budding patterns. Physiological and phylogenetic analysis suggested that these two strains were identical to Hanseniaspora pseudoguilliermondii. However, these strains produced hat-shaped ascospores and endospores, the latter of which was an unknown characteristic of the species. Endospores were produced on yeast extract-malt extract (YM) plates, though ascospores were produced on cornmeal agar of H. pseudoguilliermondii cultures. Endospores were formed in a twin-cell structure composed of a mother cell and a daughter cell, which did not separate after budding. Unlike the cell wall of the endospores, that of ascospore was stained with a chitin-specific stain. This was a feature distinguishing endospores and ascospores. Cell morphology of H. pseudoguilliermondii was compared with other species of the genus by observing their type strains. Other Hanseniaspora species did not show endospore formation under the same condition in which H. pseudoguilliermondii did. Therefore, the formation of endospores was considered to be a species-delimiting character of H. pseudoguilliermondii.

“…Since the first report describing new yeast species, Kockovaella thailandica and K. imperatae from Thailand (Nakase et al, 1991), the reports describing new yeast taxa have increased year to year and 46 new yeast species are currently recognized based on Thai isolates, 24 of basidiomycetous yeasts (Fungsin et al, 2001(Fungsin et al, , 2002a(Fungsin et al, , b, 2003a(Fungsin et al, , b, 2006Nakase et al, 1991Nakase et al, , 2006Prillinger et al, 1997;Sugita et al, 2003;Takashima and Nakase, 1998, 2000Takashima et al, 1995) and 22 of ascomycetous yeasts (Jindamorakot et al, 2004(Jindamorakot et al, , 2007Limtong et al, 2004Limtong et al, , 2005Limtong et al, , 2007aLimtong et al, , b, 2008aNagatsuka et al, 2002;Nakase et al, 2005Nakase et al, , 2007aSugita et al, 2006;Sumpradit et al, 2005;Suzuki et al, 1994).

Three yeast strains, ST-633, ST-634 and ST-635, isolated from the fruit body of a mushroom, Coprinus sp., and rotted fruit of guava collected in the western region of Thailand, were found to represent a hitherto undescribed species. This yeast is related to Pichia nakazawae var. akitaensis, P. nakazawae var. nakazawae and Pichia philogaea in the D1/D2 domain of 26S rDNA but 12 (2.3%), 13 (2.5%) and 15 (2.8%) nucleotides are different from these taxa, respectively, suggesting the distinctness of the Thai strains at species level. Since ascospore formation was not detected, it is described as a new species of Candida, Candida kanchanaburiensis. This species is distinguished from P. nakazawae by the ability to assimilate 2-ketogluconic acid and L-lysine, and inability to assimilate soluble starch.Key Words-Candida kanchanaburiensis sp. nov; new anamorphic yeast; new yeast from Thailand

“…The samples were collected from trunks of a pagoda tree (Sophora japonica L.) cultivated in a park located near Yantai (approx. coordinates: 121 u 239 E 37 u 329 N), belonging to a warm, temperate zone with continental monsoon climate in Shandong province, east China.Isolation of yeast strains from insect frass was performed by the method described by Jindamorakot et al (2004). Samples were directly streaked on acidified YM agar (0.3 % yeast extract, 0.3 % malt extract, 0.5 % peptone, 1 % glucose, 2 % plain agar, adjusted to pH 3.5 with HCl) plates supplemented with 0.025 % sodium propionate and 200 mg chloramphenicol l -1 .…”

Two strains (NYNU 121010 T and NYNU 121032) of a novel basidiomycetous yeast species belonging to the genus Sympodiomycopsis were isolated from insect frass collected from trunks of a pagoda tree (Sophora japonica L.) in Yantai, Shandong province, east China. The sequence analyses of the D1/D2 domain of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) region indicated that the closest relatives were Sympodiomycopsis kandeliae FIRDI 007 T , Sympodiomycopsis paphiopedili CBS 7429 T and Sympodiomycopsis sp. S6A. The D1/D2sequences of the novel strains differed by 12 nt substitutions (2 %) from the type strain of S. kandeliae, and by 13 nt substitutions (2.2 %) from the type strain of S. paphiopedili and from Sympodiomycopsis sp. S6A. The novel strains differed from closely related species by more than 4.6 % substitutions in the ITS region. The novel strains can also be distinguished from S. kandeliae and S. paphiopedili on the basis of a number of morphological and physiological characteristics and represent a novel species in the genus Sympodiomycopsis, for which the name Sympodiomycopsis yantaiensis sp. nov. is proposed. The type strain is NYNU 121010 T (5CICC 32998 T 5CBS 12813 T ). The Mycobank deposit number is MB 804119.The anamorphic genus Sympodiomycopsis, which is a member of the family Microstromatales, was proposed by Sugiyama et al. (1991) to accommodate the single species, Sympodiomycopsis paphiopedili, which secretes an antifungal glycolipid into the culture medium Kulakovskaya et al., 2004). An additional species, Sympodiomycopsis lanaiensis, was described in the genus (Mahdi et al., 2008), but the species has since been transferred to a new genus, Jaminaea, established by Sipiczki & Kajdacsi (2009) and based on phenotypic characteristics and molecular phylogeny (Wei et al., 2011). More recently, a novel species, Sympodiomycopsis kandeliae has been described (Wei et al., 2011). The differentiation of members of the genus Sympodiomycopsis based on morphological and physiological characteristics is potentially time-consuming, expensive and inaccurate (Sipiczki & Kajdacsi, 2009;Wei et al., 2011). As a result, there has been a shift in favour to using molecular-based techniques to improve taxonomy within the genus Sympodiomycopsis.In a survey of yeast diversity associated with the natural environment of east China, sixty-nine yeast strains were isolated from insect frass. Based on DNA sequence comparisons and phenetic characters, the majority of isolates were identified as known species: Candida glabrata, Candida melibiosica, Candida quercitrusa, Cyberlindnera jadinii, Cryptococcus flavescens, Hannaella oryzae, Lachancea kluyveri and Rhodosporidium paludigenum. Among them, two novel yeast strains, NYNU 121010 T and NYNU 121032, could not be ascribed to any known species. Further sequence analyses of the D1/D2 domain of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) region showed that these strains represent a novel species of the genus Sympodiomy...
