In country with hard, calcareous rock outcrops this grey-white, crustose lichen will be a principal species. The small, brown-black, often grey-frosted discs (0.3-0.5mm) lie in pits level with the rock surface. Close to the rock its beauty should unfold for often the first inklings of its presence are the grey, evenly scattered, frosted discs. It occurs mostly on well-illuminated limestones but can also be found among the more sheltered rocks. Throughout Ireland.
