S - Camp (Nimis & Tretiach 2004, Nascimbene & al. 2010b, Garofalo & al. 2010, Brunialti & al. 2013), Bas (Nimis & Tretiach 1999, Fascetti & al. 2006, Potenza 2006, Potenza & al. 2010), Cal (Puntillo 1996), Si (Nimis & al. 1994, Ottonello & Salone 1994, Ottonello & al. 1994, Ottonello 1996, Liistro & Cataldo 2011).

Description: Thallus fruticose, erect to subpendent, 1-5 cm high, rather firm, yellowish green to greenish white (often with blackened areas). Laciniae originating from a common basal holdfast, simple to richly branched, 0.5-1(-2) mm wide, usually compressed and more or less canaliculate, sometimes fenestrate, without pseudocyphellae. Cortex 10-15 µm thick, the chondroid cylinder continuous; medulla white, lax, hollow at least in the terminal part of the laciniae, in discontinuous patches on the inner wall of the cylinder, connected by coarse hyphal filaments. Apothecia common, lecanorine, 2-3.5(-4.5) mm across, apical or subapical, sometimes lateral, with a concave to flat, greenish disc, and a smooth thalline margin, often with a spur-like extension at the base. Epithecium pale olive; hymenium and hypothecium colourless; paraphyses thick-walled, richly branched in upper part. Asci 8-spored, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass), the wall I-, but the thin outer gel I+ blue, Bacidia-type. Ascospores 1-septate, hyaline, ellipsoid, 12-14(-16) x 4.5-6(-7) µm. Photobiont chlorococcoid. Spot tests: medulla K-, C-, KC-, P-, UV+ white: apothecial margin often K+ red, P+ red. Chemistry: cortex with usnic acid; medulla with divaricatic acid; salazinic or protocetraric acid often present in the apothecial margin.

Note: a Mediterranean-Macaronesian species found on twigs of shrubs and young trees in warm-humid Mediterranean areas, generally near the coast, almost exclusively Tyrrhenian in Italy; the record from inland Basilicata, from a humid oak forest, is somehow surprising. It is included in the Italian red list of epiphytic lichens under the “Least Concern” category (Nascimbene & al. 2013c).
