I think the most likely genus for this is another Rosellinia, but the contents of the stromata that you sectioned look rotted, unfortunately: it looks like there is another fungus growing inside. There are some other examples of uniperitheciate Xylariaceae, mostly Nemania, but a couple of Hypoxylon and Annulohypoxylon. The uniperitheciate Hypoxylon that I have seen generally have a reddish colour. The Nemania are usually black though, and can be quite hard to distinguish from Rosellinia without spores. Given all of that, I think that without further data it’s safest to leave this one at the family level, Xylariaceae.
