Bisporic discomycete
Stefan Jakobsson, 27-05-2020 22:03
In a Finnish alder swamp I found two small apothecia growing on what i thinks is remnants of leafs of Alnus glutinosa. The colour is towards brick red or light orange brown and the diameter is 1.2 mm. The flanks seem covered with adpressed hairs on top of tissue of textura angularis.

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.
