The fuzz on these midrib vein oak leaf galls has been scraped off and put in a pile to the right of the leaf. These galls have a lot of fuzz! The host oak is Quercus virginiana (southern live oak). This oak is not native in California but is sometimes planted in parks and other locations in the state. The galls are made by wasps also not native to California. Both the oak and wasp are native to the eastern U.S.
