    Are you talking about the burnt tip? In my area it would be salt burn, possibly too much water.

    Looks like a Ford truck seat. :laugh: What type of oak? The pattern probably rules out disease pustules, so my guess is a type of gall. Stretching here....best guess is gall caused by mites. Need to know what oak, then research. ???

    Just a Gall (?) spelling,. Could be a parasitic wasp unsightly but generally does no damage to the tree. Nothing you can spray or do far as I know.

    Gall wasps (Cynipidae), also called Gallflies, are a family of the order Hymenoptera and are classified with the Apocrita suborder of wasps in the superfamily Cynipoidea. About 1300 species of this generally very small creature (1-8 millimeters) are known worldwide, with about 360 species of 36 different genera in Europe and some 800 species in North America.
