English. Attacks of Phoma exigua on Hydrangea macrophylla Hanabi were observed for the first time in Lazio (Central Italy) during Spring 2005. The disease is characterized by the appearance of brown or grey leaf spot, normally circular, usually 2 to 7 cm diameter, surrounded by a yellow-red halo, frequently located on the leaf tips and margins. At later stages, young leaves may turn brown and die. Previous attacks were reported on Hydrangea spp. in Alaska (USA), Netherlands and Bulgaria
