Description: Primary thallus squamulose, the squamules large, 6-40 mm long, 2-20 mm wide, sometimes with black or white hairs at the margins, persistent, forming more or less dense, 4-10 cm broad mats, the upper surface yellowish green to greenish-grey above, the lower surface cream-coloured or more rarely white, finely arachnoid. Podetia very rare, hollow inside, up to 1.5(-2) cm tall, with irregular cups, the surface corticate, smooth, very rarely with squamules on the margin of cups. Apothecia pale brown, convex, often confluent. Asci 8-spored, clavate, thickened at apex, with a K/I+ blue tholus and a K/I+ strongly blue outer gelatinous sheath, Cladonia-type. Ascospores 1-celled, hyaline, ellipsoid. Pycnidia frequent on the primary squamules or at the margins of cups, sessile to prominent, with a colourless jelly. Conidia hyaline, curved. Photobiont chlorococcoid. Spot tests: K- or K+ yellowish slowly turning brown, C-, KC+ yellowish, P+ red, UV-. Chemistry: fumarprotocetraric and usnic acids, rarely with additional psoromic acid, frequently with traces of zeorin.Note: a mild-temperate lichen found on both calcareous and siliceous soil in dry grasslands, or in intradunal depressions, also occurring in dry-continental Alpine valleys. The C. foliacea-C. convoluta complex was revised by Pino-Bodas & al. (2010): neither morphological characters nor phylogenetic analyses gave evidence to delimit two taxa.
Growth form: Fruticose
Substrata: soil, terricolous mosses, and plant debris
