Abstract: In the course of the regional monitoring programme META ("Monitoraggio Estensivo dei boschi della Toscana a fini fitosanitari") several surveys were carried out during the last few years in forest areas of Tuscany. Disorders of pine species (Pinus pinea and Pinus pinaster) were observed mostly along the Tyrrhenian coast and in the San Rossore Regional Park. Attention was primarily paid to the disease caused to roots by the pathogenic fungi Leptographium sp. and Heterobasidion annosum. Leptographium species (L. serpens, L. lundbergii, L. guttulatum and L. wingfieldii) generally associated with Tomicus destruen, were found, and especially in already damaged plants, either fallen or struck by lightning. Isolations were positive from adult beetles and from pine chips removed from around their galleries and emergence holes in the pine bark. Leptographium spp. were also associated with breeding beetles. Although carpophores of H. annosum were quite rare, the fungal presence was confirmed by trapping basidiospores using fresh wood discs in different areas in the park, also during winter with temperatures close to 0°C. Compatibility tests showed that the H. annosum isolates from San Rossore park belonged to the P group. In the same area, the contemporary presence of Leptographium spp. and H. annosum was sometimes found in dying trees.
