However, the trees of the park were rather good for epiphytes, with virtually all of the common species being present. The most surprising for me were some rather small tufts of O. lyellii on a birch trunk - an unusual host? The purplish gemmae are just about visible in the enlarged pic, but were very obvious through a lens.

Also, can someone please put me out of my misery and tell me what the moss below is. It was growing on the base of a Sycamore in open woodland. I thought it was B. erythrophyllum at first, but the leaf margins are plane above, so I'm puzzled. The upper leaf cells are papillose. Thanks!
