Description: Thallus fruticose-filamentous, pale to dark greenish, pendulous to subpendulous, 15-30(>50) cm long, branching sympodially, mainly anisotomic-dichotomously with divergent branches. Main branches 0.2-0.6(-1) mm thick, one to several, distinct over at least half of thallus length, with distinct annulations, often with everted medulla and longitudinal cracks in the cortex, ± irregular, the segments often slightly swollen in their middle part, with the thickest part close to the base, which is black and with annular cracks. Secondary branches not constricted at attachment point, sinuous in terminal parts, mostly of equal thickness over most of their length. Papillae few to numerous, small and almost inapparent to distinct and verrucose; tubercles absent; fibrils 2-3(-5) mm long, ± regularly distributed along the entire length of branches, arranged at right angles, tending to fall off. Soralia punctiform to rarely enlarged, irregular in outline, flat to capitate/stipitate, occupying half or more the diameter of the branch, originating from fibrils or eroded papillae, with few to numerous, 0.15-0.25 mm long isidiomorphs (at least on young soralia). Cortex matt in longitudinal section, rather thick (8-13% of total branch thickness); medulla white, rather dense to compact, moderately thin (13-26%); central axis white, thick (36-51%); ratio axis/medulla ranging between 1.5 and 4. Apothecia rare, terminal or subterminal, lecanorine, 0.5-1 mm across. Asci 8-spored, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-; medulla K+ yellow turning blood-red (rarely K-), C- or C+ reddish, KC- or KC+ reddish, P+ yellow-orange (rarely P-). Chemistry: cortex with usnic acid; medulla with salazínic acid (major) and protocetraric acid (accessory), very rarely without lichen substances.
