Encrustations on beech bark
The fruiting body forms a thick and shiny black crust, on Beech (Fagus) bark and is found at all times of the year. It is not edible.[1] Young specimens are covered by a light brown outer layer. The spores are black to dark brown. B. nummularia is a common fungus specific for Fagus, and has been recorded from all parts of Europe and Russia, following the extensive distribution of its host tree. [2]
B. nummularia as a primary pathogen
The decline of European beech (Fagus sylvatica) in Sicily and Calabria (Italy) has been linked to B. nummularia and experiments have suggested that this Ascomycete plays a primary pathogenic role under certain environmental conditions.[3] It typically causes strip-canker and general wood decay.[4]
