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. 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: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: cortex with usnic acid, medulla with perlatolic acid (minor) and stenosporic acid (minor or major).

Note: a cool-temperate to southern boreal lichen found on branches and twigs of conifers and deciduous trees in montane forests with frequent fog, occasionally lignicolous and saxicolous; rare and probably declining throughout Italy.

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)
