this species puzzles me a bit. It grows under the bark of twigs (Castanea sativa according to the person who collected it) and doesn't develop much of a stromatic tissue between the perithecia but it does form small and rather well-defined pustules. Asci are long cylindrical, very thin-walled and fragile and I'm not sure about the number of ascospores but I have actually never counted more than 4 per ascus. They are also IKI-. Ascospores measure 15-21 x 10-13 µm and they are smooth, without sheaths or appendages but with a mostly straight germ slit over the whole length. Paraphyses are numerous, hyaline, filiform. Maybe you have an idea!
Best wishes,
Gernot

Re : Xylariales
Hi Gernot,
the microscopic characters of your fungus would fit Coniochaeta fairly well but the ascomata sunken in bark do not recall this genus. Did you try to search for small black setae around the ostiole?
Hope someone will come up with better suggestions.
Cheers,
Jacques

Re : Xylariales
Hi Jacques,
interesting, Coniochaeta didn't even cross my mind due to the macroscopic appearance. I haven't seen any setae but I'll have to check that again more carefully. Thanks!
Best wishes,
Gernot
