Lichen on Hawthorn

By the time we had reached the Pystyll Rhyd yr Meinciau better known as the Rhiwargor waterfalls my camera lens was wet and wouldn't focus in drizzly gloom that surrounded us. However I don't remember seeing a hawthorn so laden with lichen as this on the way to the waterfall. I've added the waterfall just to give an idea of its beauty.
