This lichen has a widespread global distribution, occurring in various regions of North America, Europe, Africa, and Asia.

It typically grows on calcareous substrates, such as limestone and dolomite rocks, in exposed and periodically wet habitats. Its thallus structure is characterized by an expansive, rosette-like cushion with a deeply lobed morphology. Notably, it lacks a true cortex. Reproductively, E. polycarpon produces abundant lecanorine apothecia and immersed pycnidia, indicating both sexual and asexual reproductive strategies. Despite its broad global distribution, the conservation status of this lichen varies significantly across differe......read more on Wikipedia.
