Unfortunately, your photo did not come through. I cannot tell you, exactly, what the problem is.
I can take a guess, though. It sounds like it could be a scale infestation. They can appear any color from white to brown to black. Killing them is not straightforward, since they seal themselves to your plants.
First, you will need to remove all that you can by hand, or with a scraping utensil. Then, you will want to treat with an insecticide, or alcohol swab.
