Conservation Status: Not of concern
Gyromitra infula has a cinnamon brown to amber brown or reddish brown, somewhat saddle-shaped cap, with a smooth to somewhat irregular, but not strongly wrinkled, surface. The stipe is round in cross-section or somewhat compressed and furrowed, white or tinted pinkish red with white mycelium at the base. G. infula and G. ambigua typically occur in late summer and fall with conifers and hardwoods on soil and wood. Although G. ambigua normally has stronger purple tones on the stipe base and somewhat darker caps, determining which of these species you have usually requires checking spore size (mostly 20--23 μm long in G. infula and 22--30 μm long in G. ambigua) and, even then, the answer might not be clear. Both species are very poisonous
