Holly Disease

Question

My holly shrubs have these clusters of tiny brown clumps at the junctions of the branches of leaves—kind of reminds me of bits of tobacco; they come off pretty easily, but many of the small branches near these clumps are going brown. What is this affecting my hollies and what should I use to get rid of it?
