hard galls
I'm assuming these galls were solid and hard if you squeezed them. Is that correct?

Interesting about Quercus acutidens -- I had to look that one up. The 1993 Jepson Manual says it's a hybrid of Q. cornelius-mulleri and Q. engelmannii, and lists it as Q. X acutidens. But Torrey who described it thought it should have species status, and there are other people more recently who are thinking the same thing -- see here.

Scrub oaks are all white oaks (as is Q. engelmannii) so knowing that it's one of the scrub oaks helps a lot with the gall identifications.
