Unknown perithecia on Osmunda!

At the end of an excursion in De Zegge Nature Reserve on April 25, 2024, I randomly took some old Osmunda stems for research.
At home I was able to identify Urceolella aspera, but with other ascomata on those stems my determination failed.
Irregularly shaped black spots were located in the vicinity of U. aspera. After the stems were soaked in water, those spots burst open slit-shaped and the hymenium was visible.
Asci: 45 x 8 µm, clavate, probably bitunate, no croziers, IKI + blue
(Pseudo) Parafysen: 42 x 1.8 µm, curled at the top and sometimes branched;
Spore: (7.5) 8.1 - 10.5 (11.1) × (2.4) 2.6 - 3.3 (3.4) µm; Me = 9.3 × 2.9 µm; Qe = 3.2;
uninucleate, lacrymoid;
Textura peridium: globosa angularis.
Could the genus be Leptopeltis?
Any help is welcome,
Regards,
François

Re : Unknown perithecia on Osmunda!
I forgot to mention that I found generative hyphae up to 3.5 µm wide!
