Abstract
Bullera species in the Trichosporonales (Tremellomycetes, Agaricomycotina) are phylogenetically distinct from Bullera alba (teleomorph: Bulleromyces albus), the type species of Bullera that belongs to Tremellales. In the present study, the three Bullera species, namely Bullera formosensis, Bullera koratensis and Bullera lagerstroemiae, and Cryptococcus tepidarius belonging to the Trichosporonales are transferred into a new genus Takashimella gen. nov. (MycoBank No. MB 810672) based on sequence analysis of the small subunit (SSU) rRNA gene, the D1/D2 domains of large subunit (LSU) rRNA gene and the ITS+5.8S rRNA gene sequences. In addition, the genus Cryptotrichosporon is emended to accommodate a novel ballistoconidium-forming species of the Trichosporonales, which is named as Cryptotrichosporon tibetense (type strain CGMCC 2.02614T = CBS 10455T). The MycoBank number of this new species is MB 810688.
