Black rot
Apple

Black rot is a disease caused by the fungus, Botryosphaeria obtusa, which can attack the fruit, leaves, and bark of any tree in the pomaceous family (apples, pears, quinces, medlars, hawthorn). Pome fruits are fleshy fruits that do not have a central stone, but are cored with small seeds. Identifying black rot early is important in stopping the spread of the fungus, as it also can be parasitic to weak or dead wood in other plants in your garden. [Note: A different species of fungus which affects grapes during hot, humid weather is also known as black rot.]
