Description: Primary thallus crustose, ephemeral and rarely seen, of dispersed, 0.15-0.3 mm wide granules. Podetia densely branched and shrubby, without a clearly defined main axis, hollow inside, pale yellowish white, isotomically-(mainly) tetrachotomously branched, 4-10(-15) cm tall, esquamulose, ecorticate, with an arachnoid surface, darkening but not melanotic at base, most branches of the same thickness, forming compact, rounded, subglobose heads which are 3-5 cm across (top of podetia regularly dome-shaped); axils between branches open or closed; terminal branchlets divergent in a star-like manner. Apothecia very 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 dark, semi-immersed on the tips of podetia, with a reddish jelly. Conidia hyaline, curved. Photobiont chlorococcoid. Spot tests: K-, C-, KC+ yellow, P-, UV+ pale blue. Chemistry: usnic, isousnic perlatolic and pseudonorrangiformic acid.Note: a circumpolar subarctic-subalpine species found in wind-protected sites with a long snow-lie, restricted to upland areas of the Alps, with a single station in the northern Apennines. It was assessed as “Endangered” in Italy by Ravera & al. (2015).
