Hymenoscyphus sp.

Last Sunday I found this Hymeoscyphus growing on leaves lying on the muddy ground. multi-species forest, including Populus. Due to time constraints, I only took a few photos. The spores didn't want to release from the ascus so I put the collection in the ripening room. Unfortunately, I moistened too little and the ascomata gently dried up. Further breeding attempts did not give adequate results. However, looking at the photos taken just after the harvest, I came to the conclusion that it may be quite an interesting species. Similar to H. imberbias but certainly not.
The content of paraffins is very weakly refracting light and tends to blend together. Ascus much longer than that of H. Imberbis. A few measured slightly exceeded 100 µm.
The only similar one that I could find in the literature is Phaeohelotium binucleatum. The problem is, I didn't capture the nucleic droplets in the photos. Some spores show something similar to them, but I'm not sure if it's them?
Anyway, I am posting photos hoping for your opinion.
Spores:
(9.5) 10.2 - 11.2 (12.2) × (3.7) 3.8 - 4.1 (4.3) µm
Q = (2.4) 2.7 - 2.8 ; N = 6
Me = 10.9 × 4 µm ; Qe = 2.7
Q = (2.4) 2.7 - 2.8 ; N = 6
Me = 10.9 × 4 µm ; Qe = 2.7

Re : Hymenoscyphus sp.
Hello Mirek,
without fully comparing the measurements (no time), I see some similiarities with Hymenoscyphus immutabilis.

Re : Hymenoscyphus sp.
Hi Lothar
I didn't know this genre but it seems it will be this genre.
Many thanks
Mirek

Re : Hymenoscyphus sp.
I agree. The apos are probably over 1 mm? H. immutabilis is comparatively large. The paraphysis content is perfect, not at all as refractive as in imberbis. But with IKI it causes a strong red reaction with extruding minute granules.

Re : Hymenoscyphus sp.
Hi Zotto
The Ascomats were quite small, about 1mm, probably because, as I said, the fruiting bodies were not yet mature enough.
The contents of the paraphyses, exactly as you say :)
Thank you
