[A new species of psychrophilic basidiomycetes yeast Leucosporidium fasciculatum sp. Nov].

A psychrophilic yeast with a basidiomycetous developmental cycle and properties corresponding to the genus Leucosporidium Fell et al. was isolated from the fruiting body of the edible spring mushroom Gyromitra esculenta Pers. picked near Moscow. However, the isolate differed from all Leucosporidium species described to date in a number of characteristics. The results of the study of the developmental cycle and of the cultural, morphological, physiological, and biochemical properties of the new isolate, strain KBP Y-3696, allow it to be assigned to a new species of the genus Leucosporidium.
