Familiar on calcareous walls and stone; it occurs as a grey, warted-areolate crust forming large circular patches limited by a thin white margin. Fruits are neat, round discs, pale brown to dark-red brown, abundantly produced, except towards the edge. Look for it on concrete, brick and mortar, especially in gardens and churchyards; also on nutrient-enriched siliceous rock.
