Hey, can anyone identify this? I think it's some sort of gall, and i think it's on an older. It's heavy, and on the ends of branches or at joins, and there are several on one tree and more in a nearby tree. Any thoughts?

@pooblemoo do you think it's something damaging enough that I need to cut it all off and burn them or something? I've never seen this type before, it's a bit alarming
