Hypoxylon sp.?

Hello all.
I would ask for help in identifying this Hypoxylon.
I'm not sure about the substrate but it was probably wood Fraxinus?
Due to the color of the extract in Koh, I can not match any species.
Wondering, a very capricious reaction to iodine. After applying only Lugol, I found only a few Ascus on which a blue color occurred. Only after the pre-treatment in KOH, the reaction was clearly visible.

regards
Mirek

Re : Hypoxylon sp.?
I probably were overworked and had problems with logical thinking?
I think that the features match Hypoxylon rubiginosum.
Someone will confirm?

That's what I was thinking.

Re : Hypoxylon sp.?
Hi Ethan.
Sometimes even quite frequent species make problems identifying and especially for people who are just starting to study such a kind, I unfortunately belong to such.
All the more I am glad that I managed to correctly determine the species.
She also helped me a second collection which I studied yesterday. Her qualities were 100% compatible with the descriptions of this species. Despite the small differences, I decided it was the same species.
Best wishes and thank you.
Mirek
