Only a few species

Three keyed in Sonoran Flora:

1a. cortex and medulla K-, apothecia persistently immersed . . . L. radiosa
1b. cortex and/or medulla K+y to r (norstictic acid), apothecia soon sitting on top of cortex . . . 2

2a. lobes plane to convex, solid, closely attached to sometimes overlapping, usually on calcareous rocks . . . L. praeradiosa s.l.
2b. lobes convex to terete, strongly swollen and ~hollow, loose, often easy to remove intact, usually on siliceous rocks , , , L. alphoplaca

The checklists are useless, since they don’t report any species. All three of the species above occur in Europe. If there are additional species in Europe in another question.
