Primary thallus: squamulose, persistent; squamules: 5-10 mm long, 2-5 mm wide, irregularly, crenate-lobate, esorediate or granularly sorediate podetia: 15-52 mm tall, up to 4 mm wide, greenish gray, unbranched or sparingly dichotomously branched, subulate, developing cups at the apices; cups: shallow, irregular, 1-3 mm wide, corticated interiorly surface: corticated below, usually completely sorediate in the upper half of their length; cortex: smooth, continuous from basal portions upwards, thinning above, becoming chinky-areolate and giving rise in places to discrete soralia; soralia: 0.5-1 mm diam., soredia: farinose to granular, but corticate patches and squamules (up to 5 mm long) sometimes occurring among soredia Apothecia: infrequent, on cup margins, pale to dark brown ascospores: ellipsoid to oblong, (8-) 14-16.5 x 2.5-6 micro meter Pycnidia: frequent, on cup margins, ovoid, sometimes slightly constricted at base, with hyaline gelatin conidia: 3-8 x 0.5-1 micro meter Spot tests: K- or K+ dingy yellow to dingy brown, C-, KC-, P+ red, UV- Secondary metabolites: fumarprotocetraric acid and accessory convirensic acid. Habitat and ecology: on old wood or thin soil over rotting wood, also on moss covered rocks, particularly at damp sites World distribution: all continents except Antarctica Sonoran distribution: Arizona, southern California, Chihuahua and Sinaloa. Notes: See discussion under C. coniocraea. In western North America C. ochrochlora varies from the type and may represent an undescribed taxon.
