Range & Status

A crustose species which has a wide overall distribution in Britain, but is currently known in England from only a few sites, south Somerset and two sites in Cornwall: on Ash Fraxinus excelsior twigs near Mawnan Smith and also on Ash in East Cornwall. It has not been found in its former localities elsewhere in southern England or in North-east Yorkshire. In Scotland it is known from five localities and has recently been discovered in Ireland, in County Fermanagh. It is mainly a boreal species growing on more or less smooth bark of deciduous species, especially Ash but also Aspen Populus tremula and Hazel Corylus avellana , in sheltered woodland.
