In summer 2003, mature trees of European beech (Fagus sylvatica)with bark cankers on the lower stem, were observed in a semi-natural pure forest within the protected area of the Abruzzo National Park (central Italy). Most affected trees were alongside paths and in coppiced stands. Symptoms of trunk gummosis were identical to those incited on beech and other broadleaved trees by different Phytophthora species, A homothallic species of Phytophthora with semi-papillate sporangia was consistently isolated from cankered bark. The objectives of this study were to identify and characterize the Phytophthora species associated with basal trunk gummosis of beech in the Abruzzo National Park.
