sp. nov. (Basidiomycota, Agaricomycotina, Tremellomycetes, Tremellales) is typified by CJDX4 Y23 (=CBS 10810 =NRRL Y-48451), isolated from forest soil in Oklahoma, USA. This species is most readily identified by the sequence of the D1/D2 domain region of the 26S rDNA and ITS (internal transcribed spacer) region. Additional strains from Oklahoma (C107DX4 Y11 =CBS 10813 =NRRL Y-48452) and Brazil (Ep11c =CBS 10812 =NRRL Y-48454; 56e =CBS 10811 =NRRL Y-48453) either had identical sequences or differed minimally. differs physiologically from the most closely related species, , by the weak or delayed assimilation of ribose and salicin, and differs from by the utilization of nitrate and nitrite and growth in vitamin-free medium.
