We use this epithet here for a species with large apothecia and a thick apothecial margin, most common on natural outcrops of hard calcareous rocks, described in Poelt & Leuckert (1995: 313-316) and illustrated in Wirth (1995: 471). A more widespread taxon with smaller apothecia and a thinner apothecial margin, often growing in anthropogenic habitats (walls, gravestones) and described in Fröberg (1997: 31, as L. crenulata), is treated as L. dispersella auct. The nomenclature of both taxa requires
further
studies.
