Pertusaria corallina (L.) Arnold
Thallus whitish grey to grey, surface usually covered by abundant, cylindrical to coralloid isidia, but these can become eroded (weathering, being sat on) to reveal the cracked-areolate thallus beneath; apothecia rare. Common in the north and west on exposed, base-poor boulders.
