Usnea glabrescens (images of British lichens)

Fruticose, ± tufted to pendulous, much branched, yellow-green to grey-green, black at base of main stem, the main stem just above the base with fine, transverse but not longitudinal cracking, branches not or only slightly constricted at their bases, terminal branches extended, flexuous, with small, rounded, often concave soralia, isidia absent (at most some slight presence on "young and punctiform soralia", fide Clerc in Nordic Lichen Flora 4, also Tõrra & Randlane (2007), as visible in photograph below). Widespread, at least in the west, typically in damp scrubby woodland, resembles the much more common U. subfloridana and probably overlooked.
