Damage caused by Chestnut blight (Cryphonectria parasitica)

Chestnut blight
Cryphonectria parasitica

Description: C. parasitica forms yellowish or orange fruiting bodies about the size of a pin head on the older portion of cankers. Spores may exude from the pycnidia as orange, curled horns during moist weather. Stem cankers are either swollen or sunken, and the sunken type may be grown over with bark. The bark covering swollen cankers is usually loose at the ends of the canker. Trees die back above the canker and may sprout below it.

Life History: The host tree dies when a swollen canker caused by fungal infection girdles the tree, preventing further growth and disrupting the transport of nutrients through the plant's vascular system. The fungus is prevalent in the environment and enters the tree through a wound site.

Habitat: C. parasitica is a pathogenic fungus affecting primarily Chestnut trees including the American Chestnut (Castanea dentate). It also attacks other hardwood tree species including Oaks.
