Bisporic discomycete

To my surprise I found only bisporic asci under the microscope. The spores are cylindrical and the size is (13.5) 14.4 - 15.96 (16.0) × (5.4) 5.6 - 6.0 (6.6) µm. The asci are on average 61.8 × 7.1 µm and the paraphyses are once bifurcately branched, cylindrical 1.5 - 2 µm wide.
This one should not be difficult to identify but so far i have failed. Any help is welcome. Thank you in advance,
Stefan

Re : Bisporic discomycete
Yeah, this is "Hymenoscyphus" kermesinus, and we had it already in this forum, I remember I regretted there that still no sequence exists of it.
Surely it is sclerotiniaceous, but to determine a genus is difficult.

Re : Bisporic discomycete
Thank you!
It looks like a Hymenoscyphus but with such hairs I did not combine it with that genus.

Re : Bisporic discomycete
These hairs are inconspicuous and may exist also in hymenoscyphus. But the shape of the ascus apex and apical ring clearly point to a Sclerotiniaceae. I chose the folder Moellerodiscus for the time being.
