Annual, sessile, semi-resupinate, solitary or imbricate, relatively flat, sometimes slightly convex above or with a small tubercle at the point of attachment, triangular in cross-section, corky-leathery. Cap surface glabrous, becoming rough with age, usually uneven, radially wrinkled, furrowed, often with small tubercles located closer to the base; initially whitish-dirty, darkening with age to reddish-brown, with concentric zones; margin often white.
The hymenophore shape changes over time: in young fruiting bodies it is tubular with slightly elongated pores, gradually transforming into labyrinthine passages as it grows, and in old fruiting bodies it may become lamellate (gill-like). Hymenophore surface ranging from pale to dark brown, sometimes reddish.
