Resumen:
Class Microbotryomycetes (subphylum Pucciniomycotina), harbors more than 200described yeast species with diversified morphological characters and ecologicaldistribution. Camptobasidiaceae family, was recently considered as incertae sedis inMicrobotryomycetes, this family includes psychrophilic genera Camptobasidium andGlaciozyma. During different surveys in extreme cold environments from the worldpsychrophilic strains were isolated belonging to a new species within Camptobasidium(Camptobasidium gelus sp. nov.) and a new genus for which the name Giraudozymagen. nov. is proposed. The species Giraudozyma psychrophilicus sp. nov. includesisolates from glacial ice from Alaska, Patagonia Argentina and Antarctica. The analysisof a draft genome for this species revealed the presence of genes encoding antifreezeproteins. The discovery of hidden diversity is essential for a better understanding of thephylogeny of Microbotryomycetes.
