Discula destructiva is a fungus in the family Gnomoniaceae which causes dogwood anthracnose, affecting populations of dogwood trees native to North America.[1]
It was introduced to the United States in 1978 and is distributed throughout the Eastern United States and the Pacific Northwest. Its origins are unknown.[2] It typically occurs in cool, wet spring and fall weather. One can avoid this fungus by watering dogwoods during drought and general cultural control care.[3][4]
Species affected: Cornus florida and Cornus nuttallii.
