Elliptical spots may form on the stem where an infected leaf meets the stem. These cankers are tan with concentric rings. They can girdle the entire stem and cause wilting of the stem above the canker. Dying flower petals are very susceptible. The fungus can either kill the flower or, if fruit is set, may grow into the developing fruit and cause a soft rot to occur.
Spots start as soft, water-soaked areas with irregular edges.
The skin of the fruit usually breaks over the decayed areas but remains intact over the rest of the fruit. A dark gray growth of fungus usually appears over the spot. When a spore lands directly on the fruit, ghost spots may develop. The spot will not rot, fruit quality is not affected. The spore is unable to cause a real infection and dies.
