A novel psychrophilic basidiomycetous species is described in a new anamorphic genus as gen. nov., sp. nov.; the type strain of is strain A15 (=CBS 10834 =DSM 21094). Two representatives were isolated from alpine glacier cryoconite and from northern Siberian sediment. Physiological and biochemical properties are similar to characteristics shared by members of the genus , although sexual reproduction is absent. strains are psychrophilic and produce cold-active pectate lyase. Sequence analyses of the ITS and 26S rRNA D1/D2 regions indicated that these strains represent a distinct taxon within the clade of the order Cystofilobasidiales, class Tremellomycetes and phylum Basidiomycota. On the basis of phenotypic and genotypic characteristics, (a member of the clade) is transferred to the newly described genus as comb. nov.
