The leaves on my black eyed Susans had white lumps on them earlier this summer. The leaves have now turned black. What is this? I have never seen it before.

It sounds like your black-eyed Susans have a mildew or fungus. Make sure you clean the bed out thoroughly this fall and dispose of all the material. In the meantime, treat your plants with an all purpose fungicide.
