I have a I believe a boxelder tree that is having branches dying and there are several of these bubbly spots on the trunk. There is also some bark pealing lower on the tree and the wood has gray/black streaking were the bark has come off. I would like to know if there are treatments of if the tree needs to be removed?

A arborist should evaluate your tree. A certified arborist is trained in pathogen identification and evaluation of tree health. They can tell you if there are treatments.
A sample can be sent to the plant disease clinic for diagnosis of the ooze.
