Ramalina thrausta (Ach.) Nyl.
Syn. Lich., 1: 296, 1860. Basionym: Alectoria thrausta Ach. - Lichenogr. Univ.: 596, 1810.
Synonyms: Alectoria crinalis Ach.; Alectoria sarmentosa var. crinalis (Ach.) H. Olivier; Ramalina crinalis (Ach.) Gyeln.; Ramalina thrausta f. sorediosula Nyl.
Description: Thallus fruticose, filamentous, long-pendent, up to 40 cm long, pale green. Branches thread-like, mostly <0.5(-1) mm in diam. Main branches interwoven, terete, widely divergent or nearly contiguous, the apical branches very thin, the tips often hooked or curled, ending in a minute punctiform soralium with a few granulose soredia; pseudocyphellae punctiform to slightly elongated, slightly raised. Cortex smooth, even, glossy, pale green, rarely with a few minute, oval pseudocyphellae; medulla white, loose, arachnoid. Apothecia never observed in Italian material. Photobiont chlorococcoid. Spot tests: K-, C-, KC- or KC+ pale yellow (cortex only), P-, UV-. Chemistry: cortex with usnic acid, medulla without lichen substances, or with an unknown substance reacting R-.
Growth form: Fruticose
Substrata: bark
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)
