Anamorphic basidiomycetous yeast strains M9962T and M9963 were isolated from water samples collected from a small stream in Ohwakudani, Hakone, a hot-spring area in Japan. These belonged to a single species and were phylogenetically closely related to Bullera lagerstroemiae, although the ability to form ballistoconidia was not observed. Based on sequence analyses of the D1/D2 domain of the LSU rDNA and ITS regions and differences in G+C content, the name Cryptococcus tepidarius sp. nov. Takashima, Sugita, Toriumi et Nakase (Trichosporonales, Tremellomycetes, Basiomycota) is proposed for these isolates, with strain M9962 T (5SP-5 T 5JCM 11965 T 5CBS 9427 T ) as the type strain. The strains grew in YM broth at 47 6C and in YM broth with the pH adjusted to 1.5 by HCl, indicating that the species is thermotolerant and acid-tolerant.

“…If the species removed to Udeniomyces and Dioszegia were excluded, only eight species would remain. The addition of new species to this genus based on its current phenotypically defined concept (Boekhout & Nakase, 1998) has made the genus more polyphyletic, expanding from Tremellales and Filobasidiales to Trichosporonales Fungsin et al, 2006). A total of 41 species are currently recognized in the genus Bullera.…”

“…If the species removed to Udeniomyces and Dioszegia were excluded, only eight species would remain. The development of an improved isolation method of ballistoconidiumforming yeasts (Nakase & Takashima, 1993) and the availability of comprehensive rRNA gene sequence databases of basidiomycetous yeasts (Fell et al, 2000;Scorzetti et al, 2002) have improved the taxonomy of ballistoconidiumforming yeasts and resulted in a remarkable increase in the number of Bullera species described in recent years (Nakase, 2000;Bai et al, 2001aBai et al, , b, 2003Fungsin et al, 2002Fungsin et al, , 2003aFungsin et al, , b, 2006Nakase et al, 2002Nakase et al, , 2004aSampaio et al, 2004;Wang et al, 2004;Luong et al, 2005).

Phylogenetic relationships among the hymenomycetous yeasts in the Cryptococcus luteolus lineage of the Tremellales were examined based on sequence analyses of the 18S rRNA gene, 26S rRNA gene D1/D2 domain, internal transcribed spacer (ITS) region including 5.8S rRNA gene and mitochondrial cytochrome b gene. In addition to the Dioszegia clade, two clades represented by Bullera mrakii and Bullera sinensis, respectively, were revealed to be well‐separated monophyletic groups in the lineage. These clades also exhibited distinguishable colony characters. Two new genera, Derxomyces gen. nov. (type species: Derxomyces mrakii comb. nov.) and Hannaella gen. nov. (type species: Hannaella sinensis comb. nov.), are proposed to accommodate the species in the B. mrakii and B. sinensis clades, respectively. Mainly based on D1/D2 and ITS sequence comparison, eight novel Derxomyces species were recognized from ballistoconidium‐forming strains isolated from plant leaves. The new species and their type strains are as follows: Derxomyces boekhoutii (AS 2.3758T=CBS 10824T), Derxomyces hainanensis (AS 2.3467T=CBS 10820T), Derxomyces linzhiensis (AS 2.2668T=CBS 10827T), Derxomyces pseudocylindrica (AS 2.3778T=CBS 10826T), Derxomyces qinlingensis (AS 2.2446T=CBS 10818T), Derxomyces simaoensis (AS 2.3571T=CBS 10822T), Derxomyces wuzhishanensis (AS 2.3760T=CBS 10825T) and Derxomyces yunnanensis (AS 2.3562T=CBS 10821T).

“…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
