Martininia with bisporic asci?

today I have collected a tiny ascomycete growing on a very decayed Fagus wood partly mixed with some excrements.
It looks like Martininia panamaensis, but the asci are mostly 2-spored, only rarely 3-spored.
There was described M. tetraspora, which was later combined as M. panamaensis f. tetraspora. So, maybe there is also bisporic form?
Ascospores in my collection measure (4.5) 4.7-5.3-5.9 (6.2) × (2.4) 2.5-2.7-3 (3.1) µm, Q=(1.65) 1.71-1.96-2.22 (2.57), n = 50.
Asci H+, IKI-, (23.9) 25.3-27.80-30.2 (32.9) × 3.9-4.2-4.5 µm.
It´s from Moravia (Czech Republic).
Thank you, Zuzana

Re : Martininia with bisporic asci?
Very interesting collection, surely a Martininia! According to photos by Jean-Claude Chasle from 2019, M. panamaensis has the very same hairs and VBs within. Regarding bisporous asci I only know "Hymenoscyphus" kermesinus. with hyaline spores and a globulosa, possibly related to Sclerotiniaceae s.str., while Martininia seems to be more close to Rutstroemia or Lambertella.

Re : Martininia with bisporic asci?
Thank you very much.
Maybe I will let it sequenced.
It´s interesting that the other collection here at AscoFrance (by Valencia Lopez) has so much larger spores than others ((7,13) 7,56 - 9,31 (14,18) × (3,83) 4,20 - 4,91 (5,21) µm).
