Description: Thallus fruticose-filamentous, brown to olive-black, pendulous, to 30 cm long, isotomic dichotomously branched towards the base, but becoming anisotomic dichotomous towards the apices, the angles between dichotomies mainly acute. Main branches much larger than the secondary ones, usually twisted and foveolate to channeled, sometimes flattened at the base, (0.3-)0.5-1.0(-2.0) mm diam, without spinules and pseudocyphellae. Soralia absent to sparse, usually tuberculate. Apothecia usually absent. Spot tests: cortex and medulla K-, C-, KC-, P- (rarely P+ red), UV-; soralia P+ red. Photobiont chlorococcoid. Chemistry: fumarprotocetraric acid in the soralia.
Note: a morphologically and chemically polymorphic, temperate to boreal-montane, circumpolar species, which is the most common species of Bryoria in Italy, and the one with the broadest ecological range, growing on bark, on sooil and sometimes even on rock in humid situations with frequent fog, sometimes reaching (in particularly humid stands) the Mediterranean belt; extinct in the Po-plain and declining. Boluda & al. (2019) proposed the synonimization of all European species of Sect. implexae (B. capillaris, B. chalybeiformis, B. implexa, B. lanestris, B. kuemmerleana, and B. subcana), except the northern B. glabra with B. fuscescens. I follow this proposal here, provisionally maintaining B. capillaris as a separate species.
Growth form: Fruticose filamentous
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)
