I get one or two of these growths on my blueberry bushes each year. At
first I thought it was some sort of cocoon, but I cut one open and
didn't see what appeared to be an insect. They usually grow at a joint
between branches and, if left alone, eventually become brown and woody.
I have some pictures of a new one I just picked off at

Look at blueberry crown gall,
Not a major pest.
Of course including your location makes these things easier to figure
