Claim: Species in Gyromitra have fruiting bodies (technically ascocarps) that can assume two different forms: it may be shaped like an ear (auriculate), or a saddle.
Evidence: The species is found in North America, where it produces fruit bodies (mushrooms) that grow on the ground. Genus: Gyromitra Genus: Gyromitra Genus: Gyromitra It is found in hardwood forests of the southeastern United States, where it fruits in early spring soon after snowmelt. Genus: Gyromitra The fruiting body, or mushroom, is an irregular brain-shaped cap dark brown in colour that can reach 10 centimetres (4 inches) high and 15 cm (6 in) wide, perched on a stout white stipe up to 6 cm (2 ⁄2 in) high. The dark reddish-brown caps of the fruit bodies develop a characteristic saddle-shape in maturity, and the ends of both saddle lobes are drawn out to sharp tips that project above the level of the fruit body.
