This loosely branching, light grey, cushion-forming (to 5cm high), rock and soil-inhabiting lichen is a common sight in upland areas. In Stereocaulon stems (pseudopodetia) support a grey mass of coral-like branches called phyllocladia. In S. vesuvianum the phyllocladia are tiny, rounded, lobed scales with dark-grey spotted centres. This distinguishes it from similar species. It grows widely on and among well-illuminated siliceous rocks. Discs are relatively common. Throughout Ireland.
