Range & Status
A very rare species found on the bark of various trees: Hazel Corylus avellana , Holly Ilex aquifolium and young Oak Quercus spp. In ancient, moist, open woodland. So far it is known only from three sites on Dartmoor (S. Devon) and three sites on the south-eastern and southern edges of Bodmin Moor, where it occurs on the trunks and branches of Holly and Hazel, but it may be somewhat overlooked. It is apparently endemic to Britain and Ireland, being otherwise known in Southern Ireland from Co. Cork. One of the Cornish sites has become somewhat overgrown and should be visited to assess any management requirements such as tree felling to allow greater light penetration.
