We've been following an individual Teloschistes chrysophthalmus on an oak twig on The Heath for the last year or so. The twig is now dead and in quite an exposed spot, just hope it isn't broken off to throw to a dog.
Since then we've found it in several locations along the crest of the Downs from Butser Hill to Old Winchester Hill always on hawthorn or blackthorn. Very much a twig lichen and often associated with Xanthoria parietina, never more than one per tree, it seems to be spread by some fairly long distance agent rather than multiplying in one location. This is a species that is extending its range northwards, we are still near the northern limit of that expansion.
