Asterotremella gen. nov. albida, an anamorphic tremelloid yeast isolated from the agarics Asterophora lycoperdoides and Asterophora parasitica

12 Tremellomycetes and Related Groups

“…Roughly onethird of all described Trichosporon species are associated with human infections or allergic diseases (Sugita 2011). Following Fonseca et al (2011) and Sugita (2011) we give Vanrija (Moore 1980) nomenclatural priority over Asterotremella (Prillinger et al 2007) for a monophyletic group of yeasts closely related to Trichosporon that lack arthroconidia and formerly were classified in Cryptococcus (humicola group) (Fig. 12.7: 15).…”

Asterotremella meifongana sp. nov. and Asterotremella nantouana sp. nov., two anamorphic basidiomycetous yeasts isolated from soil and mushrooms

“…These results clearly indicate that these five strains are representatives of two novel species of Asterotremella. Additionally, these strains demonstrated a major ubiquinone Q-9 (Table 2), which is coincident with the characterization of the genus Asterotremella described by Prillinger et al (2007).…”

“…Among the seven Cryptococcus species proposed, five with an ubiquinone Q-9 were clustered into an independent branch and included in the Trichosporonales lineage with a high bootstrap value for the sequences of SSU rDNA (Takashima and Nakase 1999;Takashima et al 2001) and multiple genes (Prillinger et al 2007). Later, Prillinger et al (2007) proposed a new genus, Asterotremella, to accommodate these species with ubiquinone Q-9 clustering within the Trichosporonales. Currently, five species are included in the genus: A. albida, A. humicola, A. longa, A. musi, and A. pseudolonga.…”

“…Because of the high degree of intraspecies heterogeneity in the Cryptococcus humicola complex, seven novel species were derived from strains previously assigned to Cryptococcus humicola based on sequence analysis of the SSU rDNA and ITS regions and DNA-DNA reassociation experiments (Takashima et al 2001). Among the seven Cryptococcus species proposed, five with an ubiquinone Q-9 were clustered into an independent branch and included in the Trichosporonales lineage with a high bootstrap value for the sequences of SSU rDNA (Takashima and Nakase 1999;Takashima et al 2001) and multiple genes (Prillinger et al 2007). Later, Prillinger et al (2007) proposed a new genus, Asterotremella, to accommodate these species with ubiquinone Q-9 clustering within the Trichosporonales.…”

“…(Fell and Statzell-Tallman 1998;Takashima et al 2001;Prillinger et al 2007). During an investigation of yeast diversity in Taiwan, five strains were obtained from soil and fruiting bodies of mushrooms.…”
