This is a microscopic, pathogenic fungus. It is necessary to observe microscopic features to confidently identify this species. Observations without microscopic details are speculative.
Without microscopic observation, this species cannot be distinguished from other fungi causing leaf spots on Mountain Laurel such as Mountain Laurel Leaf Spot (Mycosphaerella colorata (Peck) Earle).
This fungus could potentially be found throughout Maryland, anywhere that Mountain Laurel (Kalmia latifolia) grows.
