This striking, yellow-green, foliose lichen occurs widely on upland siliceous rocks, dry stone walls and boulders around Ireland. The stick-like projections (isidia) from the shiny, upper surface of the thallus should help identify it. In areas without natural acid rock outcrops, it is sometimes found on roofing tiles or in old churchyards. It is common in Ireland, especially in the west and south-west.
