    Since this was an especially cold winter, there's a good chance that your holly is suffering cold damage. Holly is native to more southern climes, and while many varieties have been developed to withstand northern winters, the weather may have been too much for yours. If it sends out leaves in the spring, all is well. You might want to take or send a sample of twig and leaves to your local extension service to eliminate the possibility of pest or pathogen.

    It sounds like sooty mold, which is a symptom of several kinds of pests that can attack hollies. I recommend treating the plants with neem oil. This will kill any pests on the plant and treat the sooty mold as well. This article will help: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm

    It sounds like your plant may have some winter burn. Fortunately, hollies are better at recovering from this than many other evergreen plants.

    I would wait to prune. Once spring is fully underway, check the damaged stems. If the are pliable, the leaves have a good chance of regrowing. If they are brittle, they are dead and need to be removed.

    This article will explain more about winter burn:

    It has what is called galls. But the cause of galls can be many. With holly, some common gall sources for holly is gall midge and sphaeropsis gall. Because the reasons vary widely for galls, I can't recommend a treatment. You should take one of the galls (the swelled areas) to your local extension service and have them examine it. With a sample, they should be able to tell you what the cause is and how best to treat it.
