Abstract:
Seven strains representing a novel yeast species belonging to the genus Cryptococcus were isolated from different substrates from Patagonia, Argentina, and The Netherlands. Three strains were isolated from a meltwater river draining from the Frias glacier at Mount Tronador situated in Nahuel Huapi National Park (Patagonia) and four were isolated from apple surfaces in Randwijk, The Netherlands. Analysis of the D1/D2 large-subunit rRNA gene and ITS region sequences indicated that these strains represent a single species that is distinct from other species of the Tremellales clade. The name Cryptococcus spencermartinsiae sp. nov. is proposed to accommodate these strains. The type strain is CRUB 1230(T) (=CBS 10760(T) =DBVPG 8010(T)).
