I've found this ascomycete on a dead lying spruce wood
I think it's Endoxyla parallela. But with amyloid apical ring? Can you confirm if this correct ?
Thanks.
Best Regards
Pavol

Re : Endoxyla parallela
Hi Pavol,
Endoxylina is a possibility but more information is needed.
You should first make a vertical section of ascomata and check if they are immersed under the surface and arranged in linear rows.
Asci of Endoxyla do have an apical ring but inconspicuous and inamyloid. It can be slightly stained in Congo red.
Ascospores of Endoxyla have a minute germ pore at one end, you should check this in heated chloral-lactophenol at high magnification. If your preparation is not thin and clean you won't see it!
Ascospores dimensions are likewise useful for identification at species level.
Best,
Jacques
