Usnea articulata (L.) Hoffm.
Deutschl. Fl., 2: 133, 1796. Basionym: Lichen articulatus L. - Sp. Pl., 2: 1156, 1753.
Synonyms: Usnea articulata subsp. intestiniformis (Ach.) Motyka; Usnea articulata subsp. mediterranea Motyka; Usnea barbata var. articulata (L.) Ach.
Description: Thallus fruticose-filamentous, pale green, long-pendent, to >1 m long, sparingly branched at base, more richly branched towards apices, with a few flexuose lateral branches. Main branches up to 4(-5) mm thick, cylindrical, smooth, the older parts constricted and inflated between constrictions (sausage-like), the surface usually smooth to sparsely papillose, sometimes with scattered comma-like pseudocyphellae. Cortex relatively thin, (5-7 % of the branch diameter); medulla white, very lax and cottony-arachnoid, especially in the inflated parts; central axis white, sometimes visible in the constrictions of old branches. Apothecia unknown in Italian material. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-; medulla K- or K+ yellowish slowly turning brown, C-, KC-, P+ red. Chemistry: cortex with usnic acid; medulla with fumarprotocetraric (main) and protocetraric acid (accessory).
Growth form: Fruticose filamentous
Substrata: bark
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by thallus fragmentation
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
