Local name: No local name known
Habitat: Terrestrial and solitary to gregarious.
Description: Fruiting bodies: 5-10 cm diameter, occasionally cup-shaped when young, saddle-shaped to tri-corner hat-shaped with even or occasionally wrinkled, Fertile surface: Yellow-brown to orange-brown to cinnamon-brown, with margin free or sometimes attached to stem, sometimes uplifted portions of margin are attached to each other. Stem: 2-9 cm long and 1-2 cm wide, equal or wider at base, surface pale pinkish-brown or sometimes developing a fine whitish over base or over entire surface with age sometimes compressed or slightly cleft. Flesh: Thin and brittle. Spore Print: Creamy white.
Comments: G. infula is characterized by uplifted, folded 2-3 times, more or less brown cap, with edges sometimes fused. Like Gyromitra esculenta it contains monomethylhydrazine (MMH) and should be avoided. Gyromitra infula is mostly likely to be confused with saddle-shaped species of Helvella with smooth stipes. e.g. Helvella compressa and H. elastica. These species can be separated by their greyer caps and pallid stipes. If in doubt, a spore examination will confirm identification, at least to genus. The spores of Gyromitras, including Gyromitra infula, have two oil droplets, while those of Helvellas have a single droplet.
