Synonyms:
Distribution: C - Tosc (Benesperi & al. 2013), Laz (Gigante & Petriccione 1995), Sar (Zedda 2002, 2002b, Munzi & Ravera 2013). S - Camp (Garofalo & al. 2010, Ravera & Brunialti 2013), Pugl (Durini & Medagli 2004, Brackel 2011), Si (Nimis & al. 1994).
Description: Thallus fruticose, greenish yellow to grey-green, often with several black dots, 1-3 cm across, formed by irregularly cylindrical, simple or sparingly branched, inflated, 2-6 mm thick, to 4(-5) cm tall, often irregularly fenestrate, hollow units arising from a common holdfast. Medulla occupying only a thin, compact layer below the chondroid cortex. Apothecia frequent, lecanorine, terminal, first immersed and concave, then often plane and to 1 cm across, with a greenish disc and a smooth, sometimes blackened thalline margin. Asci 8-spored, clavate to cylindrical-clavate, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass) never penetrating through the entire d-layer, the wall K/I-, but the thin outer gel K/I+ blue, Bacidia-type. Ascospores 1-septate, hyaline, usually curved, 10-13 x 4-5 µm. Pycnidia black, immersed. Photobiont chlorococcoid. Spot tests: medulla K+ red, C-, KC-, P+ red, UV-. Chemistry: cortex with usnic acid; medulla with salazinic acid (major) and sekikaic acid (accessory), triterpenoids. Note: a Mediterranean-Macaronesian lichen found on twigs and small branches, especially of evergreen shrubs and trees in open stands, restricted to undisturbed, open coastal forests and maquis with frequent humid winds or fog; exclusively Tyrrhenian in Italy. The record of R. inflata by Ravera & Brunialti (2013) refers to this species. The authors are often specified as “Le Prév. ex Duby”, but Le Prévost just collected the lichen described by Duby. It is included in the Italian red list of epiphytic lichens as “Vulnerable” (Nascimbene & al. 2013c).
