Lesions are small, circular, tan to brown spots that expand rapidly and may form concentric rings with orange to pink, slimy spore masses in their centers.

Lesions start as small, circular, tan to brown spots on mature or nearly mature fruit. Lesions expand rapidly, with a tendency to form concentric rings that may or may not be sunken. Lesions are firm to the touch but typically develop orange to pink, slimy spore masses in their centers. Individual lesions may reach a diameter of 4–5 cm, but may coalesce to form more extensive areas of infection (A).
