Caloplaca concilians is a species of corticolous (bark-dwelling) crustose lichen in the family Teloschistaceae. It was described as a new species in 1862 by the Finnish lichenologist William Nylander, who classified as a form of the species Lecanora ferruginea (now Blastenia ferruginea). Henri Jacques François Olivier promoted it to full species status in the genus Caloplaca in 1909.
