摘　　要：Eutypella vitis is reported for the first time on several new host trees viz.Fagus grandifolia,Fraxinus pennsylvanica and Syringa reticulata with associated branch dieback symptoms in the Niagara Region of Southern Ontario,Canada.Morphological characteristics and phylogenetic analyses of ITS sequence data confirmed the species identification.Eutypella vitis is known as a woody plant pathogen causing dieback of grapevines and other economically important fruit trees widely cultivated in Ontario.The fungus ability to infect several alternate new hosts can promote its faster and wider spread across vineyards and consequently increase a dieback hazard to viticulture in Canada.
