Atrusca capronae
If this is a desert gall on Quercus turbinella, then it was induced by a wasp, Atrusca capronae. Even though the gall is distinctive, it would be best to confirm the oak species. See https://bugguide.net/node/view/1725965

What kind of tree
Hi, thanks for responding. It's an oak tree. Not sure which species, but one of the live oaks. I'll add a photo that shows a little more of the leaves and acorns. Sorry, that's all I've got.

Probably Cynipidae
Large, spherical galls on oaks are usually made by gall wasps in family Cynipidae. I can't find one that is red and white striped. Maybe one of our gall experts knows.
