…large pale Dermatocarpon on limestone are this species. (Those on noncalcareous rock, too, usually. It’s by far the most common species here, it seems.)

But always check the lower surface of things like this — either Dermatocarpon or Umbilicaria — every so often you find one of the exciting ones with black rhizines or “tomentum” underneath.
