Mém. Soc. Imp. Sc. Nat. Cherbourg, 5: 95, 1858 ("1857"). Basionym: Cenomyce carneopallida var. cyanipes Sommerf. - Suppl. Fl. Lapp.: 129, 1826.

Distribution: N - TAA, Piem (Morisi & Sereno 1995, Isocrono & al. 2003), VA (Burgaz & al. 2020).
Description: Primary thallus squamulose, the squamules usually ephemeral, small to middle-sized, up to 6 mm long (usually much less) and c. 1 mm broad, narrowly laciniate, crenate, ascending, yellowish green above, white or yellowish-white below, the underside often sorediate. Podetia yellowish-green in upper part, greyish-green below, often with a necrotic, blue-black base, bacilliform, 2-5(-8 cm) tall, 0.5-2 mm thick, usually cupless or rarely with narrow cups, non squamulose, thin and elongate, simple or sparingly branched above, covered with farinose soredia tendind to fall off easily, leaving wide naked areas. Apothecia infrequent at the tip of the podetia, very pale ochraceous brown to yellowish brown, convex. 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 pale brown, at the tips of podetia, subcylindrical to ovoid, with a colourless jelly. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K-, C-, KC+ yellow, P-, UV- or UV+ faintly white. Chemistry: usnic, barbatic and 4-0-demethylbarbatic acids, and occasionally zeorin.
Note: a mainly boreal-montane, perhaps circumpolar species found in open heaths and forest glades amongst bryophytes and on organic soil, much more rarely on wood, in areas with siliceous substrata near and above treeline; restricted to the Alps in Italy.
Growth form: Fruticose

Substrata: soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
