Elongated sunken lesions in the branches appear on branches, often around a leaf scar, side branch or bud. At the centre of the lesion, the bark dies and may fall away. The lesions also can cause girdling of the plant or the branch to die past the lesion. Sometimes, during the Spring and Summer, small cream pustules can appear on the cankers. However, more often only small red pustules appear during the Autumn and Winter. The fungus can also infect the fruits while they're still on the tree and cause a brown rot and for them to stay on the tree over Winter.
