Very similar to Caloplaca marina but has a yellowish areolate thallus with pale yellowish-white prothallus. Numerous waxy yellowish-orange or deep-yellow apothecia.
K+ crimson / purple.

Probably very under-recorded but can form large patches on coastal rocks, concrete and walls. Found higher on the shoreline than Caloplaca marina and can extend slightly inland.
