Caloplaca chelyae is described as new to science. It is characterized by its scant crustose thallus, spores (12–)13–15 × (7–)8–11 µm, with a narrow equatorial wall-thickening, (1.5–)2–3 µm less than ¼ the length of the spore. This new species, related to subgenus Gyalolechia, was found on bryophytes in the high mountains of the Canary Islands, in El Teide National Park (Tenerife) and La Caldera de Taburiente National Park (La Palma). Possible associated taxa are briefly discussed.
