A fungal disease of woody plants causing branches to die back. Small coral-pink raised spots (pustules) form after the branch dies, that’s when you can find them on the dead branch laying on the woodland floor.
The presence of coral spot often indicates that the plant has been weakened by other factors, such as poor growing conditions, environmental stress, or other pathogen infections. Spores from the pink pustules on the bark are dispersed in rain splash and wind-blown rain. Most common on Hazel, Beech, Hornbeam, Sycamore and Chestnut.
