Oak gall - Cynips douglasii

Oak gall - Cynips douglasii
Galt, Consumnes River Preserve, Sacramento County, California, USA
September 20, 2013
Size: up to 1/2"
This is the first time that I came across a gall like this and I thought it was beautiful . I am sure that the expert Joyce Gross has come across this one before and I would like to know more about it . I think that the small Oak tree was either Valley Oak or Blue Oak , and I only found a few on 2 different trees out of maybe 100 .

Moved from Gall Wasps.

Moved from Unidentified Galls.

Moved for expert attention; what a wonder!
Moved from ID Request.

Thanks for the identification , though not an expert opinion , I think that you are correct . I did come upon a few star looking galls in the guide which has such a vast and beautiful assortment but wanted to be sure before naming it , thanks again sincerely Beth

I'm not an exptert, but...
Spined Turbaned Gall is the closest I can come up with.

They definitely are Cynips douglasii
