    There are a dozen of these small coin-sized marbles on my oak tree. Are they a fungus? Should I cut them off? They’re firmly attached to it I’m afraid of breaking the branches. It’s a small beauty oak near where I take my coffee. I’m curious as to what it really is!

    those sure look like galls – have you tried opening one? Slicing it open?

    Oak apple gall caused by gall wasp Biorrhiza pallida. The larvae live inside. galls will not seriously harm your tree. Personally I would leave them as they look kind of interesting.

    That’s definitely it! Thanks @BlueBuzzard! They have a small hole in them now I think they must have emerged in the meantime.
