Dont't think so

I was alway's told they were called bur's and occour on most broad leaved tree's.It may be a virus that does it,but I know wood turner's like them as you get a unusual grain in the wood.There is a brillent one near me on a Ash tree.

I think sometimes these

I think sometimes these growths are the result of a reaction to a pathogen, but they are solid wood, so certainly not a fungus or anything like that. They are more like a cancer than anything, but in plants such growths do not have the devastating consequences that they have in animals.
