Sordariomycete on hardwood

I haven't been able to find a name for this collection on indet. hardwood (from Styria, Austria). Any ideas are welcome!
The wood might be Tilia due to the thick layer of bast but I didn't collect the piece of wood so I don't know which trees were around at the site. If necessary I can try to determine the host by checking the anatomy of the wood.
The perithecia grow in small clusters and partly appear to lie in a somewhat valsoid configuration. At times they are embedded in what seems to be a (pseudo)stroma of some sort. They are barely visible from the outside. Asci do not appear to become detached, they are relatively long and slender, uniseriate, with a refractive apical apparatus which is not easily observable in water and does not react to Melzer's reagent. Ascospores measure 16.5-21.5 x 4-6 µm, they are hyaline to very pale brown when older, usually 3-septate with one big drop in each cell and mostly allantoid, no sheath, appendages or ornamentation observed. Paraphyses are numerous, filiform, and rather persistent.
It looks a bit similar to Björn's collection here: http://www.ascofrance.fr/search_forum/25922
Best wishes,
Gernot

Thanks Jacques, that's definitely a fitting name. :-)
