Description: Primary thallus crustose, ephemeral, rarely seen. Podetia shrub-like, hollow inside, esquamulose, ecorticate, the surface compact or finely arachnoid, pale yellowish white, anisotomically (i.e. main branches thicker) mainly trichotomously branched, 4-12 cm tall, the terminal branchlets generally - not always – spreading in all directions, not or only slightly browned at tips. Apothecia rare, brown, convex, very small. 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 dark, semi-immersed, on the tips of podetiawith a colourless jelly. Conidia cylindrical. Photobiont chlorococcoid. Spot tests: K-, C-, KC+ yellow, P-, UV-. Chemistry: mostly usnic, isousnic, rangiformic and norrangiformic acids; rarely rangiformic acid absent.
Note: a typical member of subalpine-alpine tundras, perhaps more common at higher altitudes than C. arbuscula. It was assessed as “Least Concern” in Italy by Ravera & al. (2015).
Growth form: Fruticose

Substrata: soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia
