Pertusaria warts tend to be more irregular and the apothecia should be paler / grayer (google photos of P. leioplaca, for example, and look closely). There are several Pyrenula, though, which have nice smooth rounded “warts” (perithecia) with pitch black ostioles and exciples. And hornbeams (and beeches and other thin-barked trees) are good places to find Pyrenula spp.

You are wellcome.
