The perennial stem canker disease eastern filbert blight (EFB), caused by Anisogramma anomala , is devastating to most trees of European hazelnut ( Corylus avellana ), as genetic resistance is rare in the species. The pathogen is harbored by the wild American hazelnut ( Corylus americana ) found throughout much of eastern North America. Wild American hazelnut is generally resistant or tolerant to EFB, and is fully cross compatible with C. avellana , the species grown commercially for its nuts, m
