Description: Thallus fruticose, pale yellowish green, to 5 cm tall, erect to ascending, firmly attached by a basal holdfast, richly branched, forming shrubby, rigid tufts. Branches usually compressed and partly fistulose-inflated, 1-2(-3) mm wide at base, the sterile ones often pointed and sometimes blackened at apex, with scattered perforations and rarely with a few linear pseudocyphellae. Cortex moderately thick; medulla white, very lax, especially below the apothecia. Apothecia frequent, lecanorine, with a greenish disc and a thin, smooth thalline margin, mostly terminal or subterminal on smaller branches, subtended by a short, pointed spur. Asci 8-spored, clavate, Bacidia-type. Ascospores 1-septate, hyaline, straight or curved, 11-16 x 4-7 µm. Photobiont: chlorococcoid. Spot tests: thallus and medulla K-, C-, KC-, P-. Chemistry: cortex with usnic acid; medulla with homosekikaic and sekikaic acids.
Note: on bark of old deciduous trees, more rarely on conifers, in very humid, open montane forests; a lichen which deserves further study. It was included in the Italian red list of epiphytic lichens as “Data Deficient” (Nascimbene & al. 2013c).
