an ancient hawthorn completely enveloped by lichen. Is it 'liken' or 'litchen' or both? It certainly consumed one expensive Nikon lens cap. Hawthorns seem to be prone to these dramatic efflorescences (well, no flowers but what else can one call it ...hirsuitism), which are species of
usnea and are common on isolated trees on Dartmoor and Bodmin
moor.
