Re : Help needed
Bonjour,
Perhaps you should look at Lopadostoma s.l..
The article to read is in Persoonia 32. You will find inside the definition of the genus and description of accepted species.

Re : Help needed
likely a Lopadostoma. Ascus apical apparatus should stain blue in iodine and ascospores should have a germ slit.
You need to make a vertical section through the stroma by splitting the wood. Knowing the host is very helpful, often crucial. The bark on you image does not look like that of cherry.
Use the recent monograph available at http://dx.doi.org/10.3767/003158514X679272
Good luck,
Jacques
