Pyrenomycete on Alnus glutinosa

Would perhaps someone here recognise this species I found in the recent days on Alnus glutinosa?
IKI-, CR+
Spores measure roughly:
(32.5) 33.1 - 39.9 (45.7) × (16.5) 17.4 - 19.3 (21.9) µm
Q = (1.7) 1.9 - 2.1 (2.2) ; N = 16
Me = 36.3 × 18.4 µm ; Qe = 2
Interestingly ascus seem to be very delicate and it leaks spores, also sideways, almost as soon they are thrown into a water mount and are hard to catch as whole. There was also mild frost in the last days if that might have affected something.
Location is Slovenia.
Best regards and a happy New Year!

Hi, Tomaz!
It reminds me of Dothivalsaria megalospora.
Best wishes,
Gernot

Re : Pyrenomycete on Alnus glutinosa
Hi Tomaz and Gernot, both early birds!
I agree with Gernot and I congratulte Tomaz for the quality of his illustrations, both macro- and micro-, allowing to name this fungus confidently.
The phylogenetic affinities of this taxon are questionable and still unkown. I hope someone will be interested in obtaining sequences.
All my best,
Jacques

Hello Gernot and Jacques!
Thanks for your replies. After some quick reading from old description of species it seems like a very good suggestion. The place of finding I have almost at home soo I will keep a close eye on them. :)
