Description: Primary thallus squamulose, the squamules usually ephemeral, 3-4(-8) mm long, 1-4 mm broad, crenate to irregularly lobed, ascending, glaucescent to olive-green above, whitish below. Podetia bacilliform, hollow inside, 4-10(-17) cm tall, up to 2(-3) mm thick, mostly unbranched and with pointed apices, rarely with a few branches or with small terminal cups, greenish brown to dark brown, melanotic at base, corticate for at least half of their length (the cortex smooth, finely areolate), patchily farinose-sorediate in upper part, esquamulose. Apothecia rare, brown, convex, terminal. 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 rare, dark, semi-immersed, usually along the margins of cups, with a colourless jelly. Conidia cylindrical. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P+ red, UV-. Chemistry: fumarprotocetraric acid complex.
Note: a boreal-montane to subarctic-subalpine, circumpolar species found on mineral and organic soil, but also on wood, with optimum near treeline in areas with siliceous substrata; probably 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)
