Like L. crassissima this is a species of dry underhangs sheltered from direct rain but the thallus is powdery, blue-grey to greenish and is most commonly noticed overgrowing moss cushions. The thallus tests only faintly C+ yellow or pink but is strongly Pd+ yellow to orange. Usually on calcareous siliceous rocks spreading to mosses. There are three chemotypes, only reliable separated in the laboratory.
