Phyllachora pomigena

Species of fungus

Phyllachora pomigena is a plant pathogen responsible for Sooty blotch and flyspeck disease, a disease affecting apples and pears. It appears as a brown or black blotch on the fruit. Spots may coalesce to cover the entire fruit. During the summer these diseases develop during cool rainy weather, particularly in dense, unpruned trees with poor air circulation. Although unsightly, the fruit is still edible. The sooty blotch will wipe off of the fruit.
