C ryptococcus species ( B asidiomycota) were isolated as the predominant yeast from glacial biomes of both P atagonia ( A rgentina) and the S valbard archipelago ( N orway). For a selected group of C ryptococcus belonging to T remellales, assimilative profile, production of extracellular hydrolytic enzymes and ribosomal DNA internal transcribed spacer and large subunit ( D 1/ D 2) sequences were analysed. C ryptococcus victoriae , which was originally described from Antarctica, was the most frequently found species at both locations. High variability within the species was observed and described at the genotypic and phenotypic levels, two newly described species were found in both P atagonia and S valbard: C ryptococcus fonsecae and C ryptococcus psychrotolerans . Two other new species were found only in P atagonia: C ryptococcus frias and C ryptococcus tronadorensis . Three additional new taxa were found, but they are not named as they were only represented by single isolates.
