Alectoria sarmentosa (Ach.) Ach.
Lichenogr. Univ.: 595, 1810. Basionym: Lichen sarmentosus Ach. in Liljeblad - Utkast Svensk Flora: 427, 1792.
Synonyms: Alectoria cincinnata (Fr.) Lynge; Alectoria luteola Mont. ex De Not.; Alectoria sarmentosa var. cincinnata (Fr.) Nyl.; Alectoria sarmentosa var. genuina Flagey; Alectoria sarmentosa var. sorediosa (K.G.W. Lång ex Räsänen) Du Rietz; Alectoria sarmentosa var. tortilis Sambo
Description: Thallus fruticose, filamentous, pendent, flaccid except at base, 20-40(-80) cm long, attached by a basal holdfast, branching mainly isotomic-dichotomously. Branches terete, often becoming compressed and angular-foveolate towards the base and at axils, 0.5-2.0(-2.5) mm thick, greenish grey to yellowish green; pseudocyphellae white, abundant, conspicuous, raised, elongate-fusiform to tuberculate, clearly delimited, usually c. 1 mm long. Cortex of periclinally arranged hyphae; medulla white, rather compact. Apothecia rare, lecanorine, mostly lateral, 2-3(-5) mm across, with a yellowish brown to black disc. Epithecium brown; hymenium and hypothecium colourless. Asci 2-3(-4)-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline but finally often brownish, ellipsoid, (23-)25-40(-48) x 12-25 µm. Pycnidia mainly apical, up to c. 2 mm diam., glossy black. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC+ pale yellow, P-, UV-; medulla K-, C-, KC+ red or KC-, P-, UV+ ice-blue. Chemistry: cortex with usnic acid; medulla usually with alectoronic acid (major), squamatic and a-collatolic acids (all accessory).
