Thallus: single lobed, consisting of small lobes (squamules) which are 2-6 mm in diameter upper surface: gray with epinecral layer consisting of airfilled hyphae upper cortex: 60-120 µm thick, hyaline with the outermost part (10-20 µm) brown algal layer: 60-90 µm thick mainly located in lower part of upper cortex medulla: 30-180 µm thick, consisting of dense hyphae lower cortex: 40-120 µm thick. lower surface: brown to dark brown, usually smooth Perithecia: broadly obpyriform to globose, 200290 µm high and 160-260 µm wide, with hyaline exciple which is brown at the uppermost and outermost edge asci: clavate or cylindrical, 8-spored ascospores: simple, 13-20 x 5-8 µm Pycnidia: fairly common, immersed, ostiolum similar to that of the perithecium conidia: bacilliform, 4-5 x 1 µm Spot tests: all negative Secondary metabolites: none detected. Substrate and ecology: on rocks of different types, often in seepages or in shade World distribution: Northern America and Europe Sonoran distribution: eastern Arizona and southern California.
