Phaeoacremonium fraxinopennsylvanicum (T.E. Hinds) D. Gramaje, L. Mostert & Crous 2015
This fungus is widely distributed. For example it has been reported from Europe and North America as causing trunk diseases (brown wood staining) on ash trees (Fraxinus). On grapevine, infections result in esca-like symptoms. Other trees, including various fruit trees have been also reported as hosts. The fungus disperses by airborne conidia and apparently also through insects (Mostert et al., 2006).
