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 (1.2 in) wide, with stems up to 4 cm (1.6 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.
The species was first described by British mycologist Fred Jay Seaver in 1928, who called it Paxina nigrella in his monograph of the cup fungi of North America. The type specimens were found in 1914 in Tolland, Colorado, by mycologist Lee Oras Overholts; further collections were reported from Colorado and California in 1930. The species has also been referred to as Macropodia nigrella,Helvella nigrella, and Macroscyphus nigrellus.
In 1957 Richard Korf transferred the species to its current name, changing the specific epithet in the process as Plectania nigrella was already in use (it is a synonym of Pseudoplectania nigrella). The name chosen by Korf honors the Swedish mycologist John Axel Nannfeldt, responsible for some early advances in the understanding of this fungus and other cup fungi. P. nannfeldtii is classified in Korf's section Plectania of the genus Plectania because of its ascospores.Vernacular names for the species include the "black felt cup", "Nannfeldt's Plectania", or the "black snowbank cup fungus".
