Mummy Berry

Infected flowers turn brown and wither, as if they had been frosted. Leaf and shoot growth expanding from newly opened leaf buds is blackened in the center and eventually wilts and dies. About 3 weeks after primary infection, a brownish gray mass of spores develops on blighted flower stalks and leaves.
During early berry development, diseased fruits look like healthy ones; if cut open; however, the spongy white fungal growth can be seen within the carpels. As berries approach maturity, infected berries become a reddish buff or tan color in contrast to the waxy green of healthy fruits. Many of the diseased berries fall before healthy berries are harvested. Mature mummified berries are gray, shriveled, and hard.
Apothecia can be found under bushes where leaf debris or mulch has been left undisturbed. In spring, before bloom urn-shaped apothecia emerge from the mummies and are light brown to brown. The tip of the stem is darker and eventually expands into a cup-shaped structure 0.1 to 0.4 inch wide.
