Xylariaceous fungus on Salix branch

Under a melanized thin, blackish, clypeoid pseudostroma they are these very small, roundish, glabrous, ostiolate perithecia up to 175 microns in diameter. Single or in groups up to 18-20 confluent perithecia with ostioles that allways are not collectivelly erumpent. I have not seen a true stroma and the peritecia are not in valsoid configuration.
The fungus grew on a corticated branch of Salix lying on the wet ground periodically covered by the fresh water of a lake, together with Lophiostoma appendiculatum.
The asci are shortly stipitate, up to 90 x 7 (pars sporifera up to 70), 8-spored, with an apical apparatus deeply blue in IKI and Melzer. The brownish fresh ascospores have a conspicuous sigmoid and oblique germ slit; appendages or slimy sheath are absent.
With the keys on Xylariaceous fungi I arrive to the genus Anthostomella but I don't know a good species that fits with my collection
What do you think?
Thanks again

A Lopadostoma species ?

Re : Xylariaceous fungus on Salix branch
It is another possibility but the perithecia are not in valsoid disposition and the stroma is very much rudimentary.
Thanks Alain
Thanks Alain
