A lichen similar to the common L. stigmatea, from which it differs in the usually rather thick, light thallus, large apothecia and the inspersed hymenium (containing numerous granules and oil droplets). It grows on various calcareous rocks and prefers eutrophicated sites where birds stay, such as rock tops. It is a mostly mountain species, abundant in central Europe for example in higher parts of the Alps. In contrast, it is very rare in the Czech Republic and there is only one recent record from an anthropogenic substrate (bunker) in the Krkonoše Mts (Mt Studniční hora). In the past, the lichen was reported only from the Velká kotlina glacial cirque in the Hrubý Jeseník Mts (Vězda 1961).
