Possibly Ramalina roesleri, or the other species suggested in the comments.
I forgot to take notes on what tree species it was on but probably on an oak or bay laurel because there were many around where I was hiking.
Gall formed by a cynipid wasp on the west coast. Can be greenish with yellow spots or lumps, or wine red with yellow spots or lumps. There is a curved pointed beak opposite the end of attachment. Occurs on blue, scrub, live, and leather oaks in late spring and early summer. Often remains on the oaks for several years. Wasps emerge November and December. - Ron Russo Field Guide to Plant Galls
A hybrid. Looks definitely different than Oracle Oak, but seems like Black Oak may still be one of the parents. Maybe Q. kelloggii X Q. garryana?
Was taking a side pic of this mushroom that had a hole in the top, and out wriggled the culprit as a I snapped the shot.
