Aspicilia cinerea (cinder lichen) is a gray to almost white, 1.5–15 cm (0.59–5.91 in) wide, crustose areolate lichen with large apothecia that mostly grows on rock in the mountains.[2][3]: 224 It grows in variable forms, from having a continuous surface to being areolate.[3]: 224 It grows in Eurasia, and North America on siliceous rock, schist or igneous rock in habitats exposed to sunlight, also rarely on calciferous rock.[2] It is common in Arizona, and rare in California and Baja California at elevations of 1,700 to 3,300 metres (5,600 to 10,800 ft).[2] In Nepal, Aspicilia cinerea has been reported at 4,300 m (14,100 ft) elevation in a compilation of published records.[4]
Flat to almost convex areoles are angular to irregular, and 0.2–2 mm in diameter.[2] They are contiguous but clearly separated by well defined cracks.[2] It usually lacks a prothallus.[2] It may be rimose toward the outer edges.[2] Each areole has 1–10, round to angular or irregular, 0.1–1.6 mm apothecia that may be confluent when numerous.[2] Apothecia have usually black concave discs, with exciple margins of thallus tissue.[2] Asci are club shaped (clavate), with 8 ellipsoid ascospores.[2]
Lichen spot tests on the cortex and medulla are K+ red, KC−, P+ yellow[3]: 224 or P+ orange,[2] with the medulla sometimes testing K+ yellow and P+ orange.[3]: 224 Secondary metabolites include norstictic acid and often connorstictic acid in traces, and more rarely hyposalazinic acid.[2]
