Description: Thallus fruticose, shrubby to subpendent, up to 5 cm long, grey-brown to greenish brown, sparingly to richly branched, the branches to 1.2 mm thick, becoming progressively thinner towards the apices, subterete to flattened (especially in basal parts), densely and finely hairy to totally glabrous, sometimes diffusely blastidiate (especially in sterile specimens) and/or with spiniform papillae. Cortex 60-200 µm thick, of conglutinated, thick-walled, mostly longitudinally oriented hyphae, sometimes with an amorphous layer which gives rise to short lateral hyphae reaching the surface; medulla lax to almost absent, of loosely interwoven hyphae, often with strands of conglutinated, longitudinally oriented hyphae below the cortex. Apothecia lecanorine, most frequent in non-blastidiate specimens, to 1.2 mm across, mostly lateral, with a brown-black to black disc and a smooth thalline margin. Asci 8-spored, clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1(-2)-septate, brown, ellipsoid, 20-26(-30) x 10-15 µm, the septum c. 6.5 µm thick, intermediate between the Orcularia and Physconia-types, the wall ornamented. Pycnidia rather common, immersed, with a dark brown ostiolum. Conidia hyaline, fusiform to bacilliform, 3.5-4.5(-5) x c. 1 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: on a wide variety of substrata, most frequent on branches of littoral shrubs but also on rocks, and, but only in a few very warm-humid areas, even on mortar (e.g. it is still abundant in the village of Erice in Sicily); much more widespread in the past, but presently restricted to a few, localised stations with natural vegetation, especially sand dunes, mostly along the Tyrrhenian coast, in sites with a high persistence of fog, or with frequent humid maritime winds alternating with dry periods. It is included in the Italian red list of epiphytic lichens under the “Least Concern” category (Nascimbene & al. 2013c).
