Aspicilia Verrucigera
''Aspicilia'' (sunken disk lichen) is a genus of mostly crustose lichen, crustose areolate lichen, areolate lichens that grow on rock. Most members have black apothecia discs that are slightly immersed in the areolas, hence the List of common names of lichen genera, common name.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Most of the species of this genus grow on calcareous and acidic rocks and most of the taxa prefer temperate and arctic habitats. Some members of the genus ''Aspicilia'' are pioneer species on granite and other hard rock, after which members of other lichen species may grow on them, such as members of ''Acarospora''.ACAROPSPORA, Lichen Flora of the Greater Sonoran Desert Region.

Aspicilia Cinerea
''Aspicilia cinerea'' (cinder lichen) is a gray to almost white, 1.5 – 15 cm wide, crustose lichen, crustose areolate lichen with large apothecia that mostly grows on rock in the mountains.Lichen Flora of the Greater Sonoran Desert Region. Vol 3., Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001/ref>Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, It grows in variable forms, from having a continuous surface to being areolate. It grows in Eurasia, and North America on siliceous rock, schist or igneous rock in habitats exposed to sunlight, also rarely on calciferous rock. It is common in Arizona, and rare in California and Baja California at elevations of . Flat to almost convex areoles are angular to irregular, and 0.2 – 2 mm in diameter. They are contiguous but clearly separated by well defined cracks. It usually lacks a prothallus. It may be rimose toward the outer edges. Each areole has 1 – 10, round to angular or irre ...
