This soil-inhabiting crustose lichen is a soft, granular grey turning to green when wet. It has orange-pink discs (flat and broad or convex) which stand out clearly in the field against the thallus. It is a species of upland and moorland habitats, especially of peaty soil and damp tracks. A dab of fresh bleach (C) has no effect on colour. Mainly north-west Ireland; scattered elsewhere.
