White and hairy on Equisetum

The combination of those spores, outer hairs and lanceolate paraphyses seems a bit strange to me. Could this be something like Mollisiopsis or Pyrenopeziza?
Spores:
(14.5) 16.2 - 19.8 (20.8) × (2.6) 2.8 - 3.19 (3.2) µm
Q = (5.1) 5.2 - 6.9 (7.9) ; N = 15
Me = 18.1 × 3 µm ; Qe = 6

Re : White and hairy on Equisetum
This should be studied in living state, only the spores are alive on your pics. Perhaps a Psilachnum. There is a P. equisetinum but spores are only 6-8 x 1.5-2 (dead).

Re : White and hairy on Equisetum
Ok, that genus again... The first two pics are from fresh material in water, others in IKI.

Re : White and hairy on Equisetum
Ah, it may be that some of the paraphyses are alive and look multiguttulate.
How long are the hairs? They also might resemble those of Albotricha.
Apothecia of Albotricha are larger than those of Psilachnum. Psilachnum usually has a conspicuous drop in the living asci.

Re : White and hairy on Equisetum
Here's a few new pics. It's hard to measure the hairs, they seem to be stuck together in messy clumps. But I got something like 100 microns. All the asci have narrow mouths, croziers+.

Re : White and hairy on Equisetum
O.k., there seems to be an exudate on the hairs.
Do the asci always contain 8 spores or are some 4-spored?
There is an Albotricha washingtonensis = Lachnaster miniata on ferns with much smaller spores,which is a Psilachnum probably.
For Equisetum my database has nothing.

Re : White and hairy on Equisetum
I didn't pay that much attention to the spore count but I think at least most of them had eight. Doesn't quite seem to fit anything...
