We moved into our house last August. Ever since we have lived here, our very large Oak in the backyard has had these tumor looking growths all over it. There are none on the trunk, just on the branches. I didn't know if anyone could help me identify what this might be. They break apart very easily.

Thank you for your help!

P.S. Couldn't figure out how to post more than one picture. I have another picture I could show, if that would be helpful.
