Synonyms: Desmazieria evernioides auct.; Ramalina duriaei (De Not.) Bagl.; Ramalina evernioides auct. non Nyl.
Distribution: C - Tosc, Laz, Sar (Zedda 2002, 2002b, Rizzi & al. 2011, Di Nuzzo & al. 2022). S - Camp, Pugl (Nimis & Tretiach 1999, Durini & Medagli 2004), Bas (Fascetti & al. 2006, Potenza 2006, Potenza & al. 2010), Si (Nimis & al. 1994, Ottonello & Salone 1994, Grillo & Cristaudo 1995, Grillo 1998, Czeczuga & al. 1999, Grillo & Caniglia 2004, Caniglia & Grillo 2006b, Ravera & al. 2024).
Description: Thallus fruticose, shrubby, rather soft, yellowish green to greenish white, dull, consisting of up to 5(-12) cm long, 5-10(-20) mm wide, palmately or irregularly branched, reticulately ridged (especially on the lower surface), flattened laciniae growing from a basal holdfast; pseudocyphellae absent or scarce. Main laciniae monophyllous, with numerous, small, marginal secondary branches; soralia starting as eroded patches on the cortex, later occupying entire lobe ends, especially on the underside; soredia 20-40 µm in diam., farinose. Cortex very thin, of a single prosoplectenchymatous layer, lacking chondroid strands; medulla white. Apothecia and pycnidia very rare (not observed in Italian material). Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC+ yellowish, P-, UV-; medulla KC-. Chemistry: cortex with usnic acid; medulla with bourgeanic acid.
Note: a mainly Mediterranean-Atlantic lichen recently reported also from the Americas, found on twigs, more rarely on rocks in maquis vegetation near the coast; mostly Tyrrhenian in Italy. An earlier record from Emilia (see Nimis 1993: 600), being dubious, is not accepted here.
Growth form: Fruticose

Substrata: bark and rocks
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
