Stereocaulon symphycheilum is a rare species with terminal globose soralia and phyllocladia with a dark central part and paler margins. From similar S. vesuvianum it is distinguished by the absence of stictic acid and presence of lobaric acid (UV+). The species grows on siliceous rocks and stones, often on substrates rich in iron and copper, including anthropogenic stands, such as spoil piles. It is an arctic-alpine species, mainly known from the Alps and Scandinavia. In the Czech Republic, it is only known in České Švýcarsko (Bohemian Switzerland National Park), where it is locally abundant. It grows on exposed tops of sandstone rocks, often enriched with iron oxides.
