Lophiostomatoid fungus on Arbutus unedo

I have found small, rounded, gregarious, non-stromatic pseudothecia, semi-immersed in the bark of branches of Arbutus unedo still attached to the tree, revealing only a papillate ostiole which is usually broad and laterally compressed. The caudate ascospores are hyaline or light brown at maturity, smooth and they have many transverse and occasionally some vertical or oblique septa, they do not appear to be surrounded by gelatinous sheaths but seem to have inconspicuous conical polar appendages. The base of the asci is twisted and thinned towards the end.
Do you have any ideas that could help me?
Platystomum? Sigarispora?
