subsequently found in Lanhydrock Woods in 1995 and at Boconnoc Estate in 2006.

Habitat & Ecology

In Cornwall, primarily associated with Daldinia fungus growing on Ash Fraxinus excelsior in ancient woodlands and pasture-woodlands; will also breed under fungoid Beech Fagus sylvatica bark, with black encrusting Hypoxylon fragiforme on dead and dying Beech.


Loss of the older age classes of Ash and Beech from native woodlands.


Retention of overmature trees and their associated deadwood.
