Cap: 2-7 cm; convex to bell-shaped, quickly becoming flattened or centrally depressed; moist or dry; bald at first, but soon becoming roughened-scurfy and wrinkled; dark reddish brown to orangish brown when very fresh and young, becoming burnt orange to pinkish brown or orangish brown; the margin becoming lined and/or scalloped.
