Wynnea americana

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.

§1

Description

The fruit bodies (technically called apothecia) of W. americana are erect and spoon- or ear-shaped, and may reach up to 13 centimetres (5 inches) tall by 6 cm (2+1⁄4 in) wide with the edges usually rolled inward. The outside surface is dark brown–purplish, while the inner surface—the spore-bearing hymenium—is pinkish orange to dull purplish red or brown at maturity. The outer surface may develop wrinkles in maturity. The apothecia, which occur singly or in groups of up to about 25, arise from a short stalk. The stalk is variable in length and solid, dark outside, white within. The stalks originate from a sclerotium, a compact mass of hardened mycelium. The sclerotium has an almost gelatinous consistency with irregularly shaped lobes and internal chambers, and may reach a diameter of 4 to 6 cm (1+1⁄2 to 2+1⁄4 in). The sclerotium's function is thought to supply moisture and nutrients, or to serve as a resistant structure capable of sustaining the fungus through times of stress. W. macrotis is the only other species in the genus to bear a sclerotium. Wynnea americana has no discernible odor, and its taste is unknown. It has been described as inedible due to its toughness. Clusters of fruit bodies are connected by large underground masses of compacted mycelia known as sclerotia. …

Range & habitat

In North America, W. americana has been collected from several locations, including Tennessee, New York, West Virginia, North Carolina, Ohio, and Pennsylvania. It has also been collected in Mexico, Costa Rica, India, and Japan. The fruit bodies grow solitarily or in clusters on the ground in deciduous forests, and prefer moist, organic soils. In both Asia and North America, fruit bodies are most often produced during August and September. The single Central American collection, from Costa Rica, was made in early November.
