In the shape of apothecium this is Xylographa parallela (Xylographaceae in Baeomycetales, Ostropomycetidae).

Yes, I agree it is a Xylographa, but it may well be also another species of the genus. Thallus / apothecia character as well as chemistry should be considered. In the worst case sequences. On the Research Gate the monograph by Spribille et al. should be possible to download:
