Wow. I was really intrigued by your photo. I've seen some weird gall before but not this one. I agree with Sooby on the elm gall. Caused by an aphid. Heres a link that gives a short overview of what the causes are and what can be done. Thanks for posting this one. [url] http://www.mortonarb.org/trees... [/url]

They look like galls. Close to the elm galls if you scroll down the page linked below. What tree are they on?
