The ecology and taxonomy of the snowbank fleshy fungi in the vicinity of Mirror Lake, Uinta Mountains, Utah were investigated during 1963, 1964, and 1965. A total of 59 speciaes, representing the Agaricales, Polyporales, Thelephorales, Gastromycestes, Myxomycetes, Dacrymycetales, and Ascomycetes, were found associated with the snowbanks. Four of these species (Geupiniopsis alpinus, Polyporus alboluteus, Polyporus leucospongia and Sterile myclium I) have presence percentages of 100% and three (Stereum Rugisporum, Dasyscypha arida and Herpotichia nigra) had presence percentages of 90%. The lignicolous fungi were found to be more frequent around the snowbanks than either the terrestrial or coprophilous fungi. No fleshy fungi were found fruiting in association with the snowbanks in wet meadows. All terrestrial fungi found in association with the snowbanks were found either around snowbanks in the forest or in the transitional zone between the forest and the wet meadows. Twenty-two species began their development under the snow. Sporocarps kept buried in the snow did not develop a mature hymenium while in the snow, whereas similar sporocarps where the snow was allowed to melt developed mature hymenia in the same period of time.
