Venturia tremulae Aderh. 1897
This species is one of several fungi from the genus Venturia causing shoot blight and shepherd's crook symptoms on poplar and aspen (see also Venturia populina). Typically, dark brown or black leaf lesions develop during spring which spread over the entire leaf, the petiole and the shoot. Outbreaks develop on young trees during wet conditions when most shoots of a tree may become infected. Growth of the trees is affected and seedlings may be killed in extreme cases.
Asexual spores are formed during the summer and cause secondary spread of the disease. Sexual fruiting bodies (pseudothecia) develop later in the year, overwinter and initiate new infections in spring through the release of ascospores.
