W. americana W. gigantea W. intermedia W. macrospora W. macrotis W. sinensis W. sparassoides Wynnea is a genus of fungi in the family Sarcoscyphaceae.
Circumscribed by Miles Joseph Berkeley and Moses Ashley Curtis in 1867, the genus contains seven species that have ear-shaped fruit bodies that grow on the ground.
[1] The former specimen was collected by Botteri near Orizaba, Mexico, and the latter had been described by Berkeley in his Journal of Botany and Kew Garden Miscellany (1851)[2] Both species were subsequently illustrated in Cooke's Micrographia.
Standing erect, the ear-shaped apothecia are several- to many-clustered on a common stalk that arises from a sclerotium, a hardened mass of mycelium buried in the earth.
The ascus has a thickened apical ring capped by a hinged operculum; its opening often is oriented obliquely, a condition referred to as suboperculate.
