title: Cryptococcus antarcticus var. circumpolaris var. nov., a basidiomycetous yeast from Antarctica.
abstract: Cryptococcus antarcticus Vishniac & Kurtzman var. circumpolaris Vishniac and Onofri var. nov. (Filobasidiales, Tremellomycetidae, Hymenomycetes), an anamorphic yeast with ca. 73% nDNA relatedness to Cryptococcus antarcticus var. antarcticus, differs in failure to assimilate raffinose, a lower maximum temperature for growth, fatty acid profile, and in a single nucleotide change in the D2 region of LSU rDNA.
