Found on a twig, possibly hawthorn, under an old hedgerow. Twig approx 1cm diameter. The lichen is a tight grey-green clump 2.5-3cm diameter. There were no apothecia. Main stems blackened at base (see photo 2). Very little cracking of stems visible. I'm confident that it is a Usnea. The closest match I can find is U. subfloridana.
