The fungus that causes Leaf Spot Disease on Eastern Redbud (Cercis Canadensis). Other species of this fungus cause leaf spot on a variety of ornamental and fruit trees/shrubs, including citrus. Pinpoint clusters of black dots surrounded by discoloration, that coalesce to form necrotic areas which may eventually form "shot holes" (areas that drop out). Tendrils of white sporangiophores and sporangia can be seen (with a hand lens) coming from infected tissue, especially along the major leaf veins.
