Hi All, Recently I found this minute Bryoscyphus
Haematomyxa vinosa

Hello again!
Last weekend in Northern New Jersey I found what I believe to be Haematomyxa vinosa. It was growing on an unknown hardwood in association with Berkleasmium conglobatum. Rough and sometimes irregularly shaped black discs reaching about 1mm in diameter, they have a burgundy tinge.
The asci are bitunicate. In section there is purple pigment between the asci. Spores inside the asci are golden brown, muriform and larger than ejected spores—about 40 x 14µm. Ejected spores—I managed to get about 6 of them— are darker brown and 28.2-36.5 x 11.7-15.6µm. They are constricted at the central septa and usually curved. In KOH the apothecia emit an olive green/gray green pigment. I did not see paraphyses, perhaps I missed them.
My determination of Haematomyxa vinosa was only possible when I rediscovered this post I made from 2017:
Although there is a partly unresolved conversation in that post, I feel that the determination is fairly solid, but I am open to other thoughts. Other thoughts?
It is remarkable to me how infrequently this asco is collected. I see only one observation of it on iNaturalist, three records in Mycoportal.

Re : Haematomyxa vinosa
Hi Ethan
I am sure it is! Yes, I know no other record than you indicate.
