Sporobolomyces magnisporus sp. nov., a new yeast species in the Erythrobasidium cluster isolated from plants in Taiwan

Abstract

Two strains of yeasts that contain Q-10 as the major ubiquinone, lack cellular xylose and produce large bilaterally symmetrical ballistoconidia were isolated from plants collected in a protected subtropical rain forest in Taiwan and were found to represent a new species. The taxonomic properties of this species coincide with the genus Sporobolomyces, so it is described as Sporobolomyces magnisporus sp. nov. In phylogenetic trees based on the nucleotide sequences of 18S ribosomal DNA and D1/D2 domain of 26S ribosomal DNA, this species is located in the Erythrobasidium cluster.

Sporobolomyces fushanensis sp. nov., a new species of ballistoconidium-forming yeast in the Microbotryum lineage isolated from a plant in Taiwan

“…However, only a few reports have been published on yeasts living in the phyllosphere of Taiwan (Nakase et al, 2002(Nakase et al, , 2003(Nakase et al, , 2004. In the course of a survey of yeasts in the phyllosphere of the Asian region, we found a yeast strain coinciding with the genus Sporobolomyces from a plant in Taiwan.…”

Sporobolomyces diospyroris sp. nov., Sporobolomyces lophatheri sp. nov. and Sporobolomyces pyrrosiae sp. nov., three new species of ballistoconidium-forming yeasts in the Agaricostilbum lineage isolated from plants in Taiwan

“…One hundred and forty-six of them produced ballistoconidia and were assigned to the genera Bullera (91 strains), Kockovaella (1 strain), Sporobolomyces (53 strains) and the yeastlike fungus Tilletiopsis (1 strain). Among strains assigned to the genus Sporobolomyces, two strains forming large ballistoconidia were found to represent a new species in the Erythrobasidium cluster and described as Sporobolomyces magnisporus (Nakase et al, 2003). Another three strains are closely related to species in the Agaricostilbum/Bensingtonia cluster (Hamamoto and Nakase, 2000) or Agaricostilbum lineage (Scorzetti et al, 2002) Takashima 1 undescribed species.…”
