Wynnea americana, commonly known as moose antlers or rabbit ears, is a species of fungus in the family Sarcoscyphaceae. The uncommon species is recognizable by its spoon-shaped or rabbit ear–shaped fruit bodies that may reach up to 13 cm (5 in) tall. It has dark brown and warty outer surfaces, while the fertile spore-bearing inner surface is orange to pinkish to reddish brown. It is distinguished from other species in its genus by the pustules (small bumps) on the outer surface, and microscopically by the large asymmetrical longitudinally ribbed spores with a sharply pointed tip. The spores are made in structures called asci, which have thickened rings at one end that are capped by a hinged structure known as the operculum—a lid that opens to release spores from the ascus.
In eastern North America, where it is typically found growing in the soil underneath hardwood trees, the inedible species is found from New York to Michigan south to Mexico. It has also been collected from Costa Rica, India, and Japan.
