We show that certain subrings of the cohomology of a finite p-group P may be realized as the image of the restriction map from a suitable virtually free group containing P as a subgroup. We deduce that the cohomology of P is a finitely generated module for any such subring. Examples include the ring of `universally stable elements' introduced by Evens and Priddy, and rings of invariants such as the mod-2 Dickson algebras.
