I attached a photo. My 4-5 year old peach tree has developed these raised, black bumps that are gooey. If I run my finger along the bumps, they fall off easily. They're all over the tree, the trunk, branches old and not too many of the newer branches. I live in Northwest Ohio, so the past 2 winters were very harsh. I did not have fruit, but I do this year. How do I identify what's on the tree and how do I treat it?

I have not been able to identify this infestation. It would not appear to be a fungus, most likely insect infestation of some kind (since they come off) I would treat this with Neem Oil as it does work as both a fungicide and insecticide.
