Description

 An encrusting yellow-orange to bright orange lichen. The thallus is composed of small granules or 'islands' of tissue but is never powdery. When well developed the crust may be composed of small convex islands of tissue often with a paler edge. Disc-like, convex and deep reddish orange fruiting bodies occur on the surface of the thallus.Caloplaca marina is one of several species of Caloplaca found on rocks at or above high water. Caloplaca thallincola may occur at the same position but prefers sheltered conditions. Caloplaca thallincola is a lighter orange with a distinct lobose margin. Caloplaca maritima is also similar but is never orange and the thallus is composed of more convex, paler, wax-like islands of tissue. Identification to genus or species level may require simple chemical tests; for details see Dobson (2000).
