Enterographa sorediata

Range & Status

This crustose lichen occurs mainly on the dry side of trunks of mature Oak Quercus spp. not directly wetted by rain. It is restricted to relatively open ancient woodland. A rare, possibly overlooked, endemic species recorded from southern and south-eastern England. It has been found in at least eleven woods in the New Forest, one site in Savernake Forest (Wiltshire) and in one site in each of Dorset and Norfolk; in each case confined to a single tree. Recently, (2009), it has been found on eight old oaks on the Lanhydrock Estate (National Trust) and on a single oak in Millook Wood (Woodland Trust) in northeast Cornwall. The main threat is from the destruction of the host trees on which it grows and the destruction of potential host trees close to extant colonies. It receives general protection under the Wildlife and Countryside Act 1981 and is a Priority (BAP) species with its own Species Action Plan.
