Abstract
Twenty-one psychrophilic yeast isolates related to theCamptobasidiaceaefamily in theMicrobotryomycetesclass were obtained from ice collected from cold environments worldwide. A new psychrophilic species from the recently described genusCryolevonia, Cryolevania giraudoaeis proposed to accommodate 18 isolates from Patagonia (Argentina) and Antarctica (holotype CRUB 2086T). In addition, a new psychrophilic species in the genusCamptobasidiumis described asCamptobasidium gelussp. nov. (holotype CBS 8941T), based on three isolates from glacial ice in the Russel glacier (Greenland ice sheet) and Antarctica. The strict psychrophilic profile is the salient feature of both novel species.Keywords
