On Engelmann oak in Santa Barbara botanic garden. Unlike a blister gall, there is a well defined, somewhat lumpy, mostly flat abaxial organism associated with each adaxial pimple. But unlike the plate gall that white oaks host, these don't seem detachable, plus with Andricus pattersonae there's no adaxial deformation (as there is here in this observation), just downstream damage. And this is well out of range. Last photo is probably of something completely different using the same space, but who knows?!
