In this paper, we point out that when p is a prime, the additive structure of the Hochschild cohomology ring of a p-block of a finite group G satisfies the now-familiar type of alternating sum formula using the p-subgroup complex of G. (Throughout, we work with the Tate version of Hochschild cohomol
