Plectania nannfeldtii, commonly known as Nannfeldt's Plectania, the black felt cup, or the black snowbank cup fungus, is a species of fungus in the family Sarcosomataceae. The fruit bodies of this species resemble small, black, goblet-shaped shallow cups up to 3 cm (1+1⁄8 in) wide, with stems up to 4 cm (1+5⁄8 in) long attached to black mycelia. Fruit bodies, which may appear alone or in groups on the ground in conifer duff, are usually attached to buried woody debris, and are commonly associated with melting snow. Plectania nannfeldtii is found in western North America and in Asia, often at higher elevations. Similar black cup fungi with which P. nannfeldtii may be confused include Pseudoplectania vogesiaca, P. nigrella, and Helvella corium.
