Stereocaulon pileatum is easily recognizable based on persistent primary thallus and low pseudopodetia with terminal globose soralia. It grows on various rocky substrates without calcium, often enriched with metals. It can also be found on anthropogenic substrates, such as roof tiles. In Europe, the species is mainly distributed in Scandinavia and Great Britain, otherwise it is rare. In the Czech Republic, it is quite rare, found at middle and higher elevations, mainly on extrusive rocks.
