Have a transplanted native Ironwood. Has had some dead wood. tonight I noticed some of the dead wood has a coating that looks like a cross between sand and mud. It knocks off llike dead bark. wood underneath is hard, pale, and has lots of tiny black dots. Any idea what this is? How do we treat it? Do we need to? Could this be termites?
