This species has a grey thallus of long, narrow lobes which widen and become brown at their tips. The upper surface has a "furry" appearance whilst the lower is white and lacks a lower cortex (the hyphaea form a loose mat). Cilia line the margins of the lobes and these may be the same colour as the thallus, or darker. Apothecia are common in unpolluted areas, with black, frequently pruinose discs and borne on short stalks. They are about 5 mm in diameter with margins that become crenulate. Chemical Reactions: All negative.
