I would then say that it is just natural elm heartwood. Remember your tree physiology. On the outside you have bark, then phloem, then the typically green cambium layer, then inside that, the sapwood, and right in the middle the heartwood. The bark and the heartwood are both dead tissue. In elms (to my knowledge) the dead heartwood is brown and the sapwood is a lighter colour. I think that's all you are seeing here, so no need for concern.
