Biscogniauxia nummularia: pathogenic agent of a beech decline
Decline of European beech (Fagus sylvatica) in Sicily and Calabria (Italy) was observed to be associated with the ascomycete Biscogniauxia nummularia. This fungus is naturally present in beech stands and to date has not been considered a primary pathogenic agent. Artificial inoculations were performed to assess its pathogenicity on beech and to determine if Sicilian and Calabrian isolates differ in virulence. Biscogniauxia nummularia played an evident primary pathogenic role under the environmental conditions studied. Virulence of the isolates was variable and did not depend neither on the geographic origin nor the environmental conditions at the sites where pathogenicity testing was performed.
