Abstract:
Two yeast strains isolated from the moss Chorisodontium aciphyllum from the Fildes Region, King George Island, maritime Antarctica, were classified as members of the genus Cryptococcus based on sequence analyses of the D1/D2 domains of the large subunit rRNA gene and the internal transcribed spacer (ITS) regions. The rRNA gene sequence analyses indicated that the two strains represented a novel species of the genus Cryptococcus, for which the name Cryptococcus fildesensis sp. nov. is proposed (type strain: CPCC 300017(T) = DSM 26442(T) = CBS 12705(T)). The MycoBank number of the novel species is MB 805542.
