difficulties with determination continues. Once again I'm not sure even of the genus. I thought to be collecting some Gorgoniceps, but nothing in NM1 fits.
These dark based, short stipate are up to 0,6 mm wide. The hymenium is greyish brown.
The spores seems to develop slowly, because I had to study many mature looking ones to find mature spores. The spores are 15-30x2-3 and develop 1-3 septas.
The asci are 90-120x6-8, IKI blue and paraphyses are 2-3 wide and have multiple droplets. The cells are long and brown.
Ideas?

Re : On Pinus needles
Yes indeed! This is Phialea fumosella, and it has no genus name. I think Antinoa/Phialea strobilina should stand in the same genus. There are two possible discoid anamorphs, a yellow one and a grey one with long teeth (Xiambola mirabilis). You did not see either of them?
These morphs should be sequenced to clarify their relationship among another and to strobilina.
I would be glad to know at least the collection data, better also the site name. Pinus sylvestris I assume?

Re : On Pinus needles
Dear Zotto,
indeed, there where some smaller yellow ones growing on the needles of Pinus sylvestris. You may see one on the macrophoto, which is poor because the sun has not been shining here lately...
Actually I collected this twice this autumn. The mature ones where of the 1. collection, that I had for a (too) long time in the fridge.
Collection data: Finland, North Savonia, Kaavi, Pienet Teyrilammet, ETRS89: 62° 47' 13''; 28° 56' 31'', 10.10.2016
And Finland, North Carelian, Outokumpu, Koiralamminsalo, 62° 45' 16''; 28° 57' 57'', 6.10.2016
Do you need a specimen?

Re : On Pinus needles
No, I do not need, no time at all.
So all your photos here are of the 1st collection?
I see the yellow one. If you test it you should see 1-septate rod-shaped conidia.
I think that Timo Kosonen could take this species in culture, or sequence from apothecia. It may fall in relationship of Phialina/Calycellina.

Hi,
shame on me, naturally you are busy.
Specimen was allready asked for cultivation to Germany...
