On Pinus needles

Hello,
these ascos are estimately 0,1 to 0,3 mm wide.
The snow is just melting away here and I,m been looking for Desmazierella, but think, that I'll find everything else ;)

Re:On Pinus needles
The asci are about 60-80x 5-7 and paraphyses about 2 micrometers wide and there is a lot of them. They have something inside either septas or droplets.
I suppose, that the spores are filiform and septate and are about 35-50x2 micrometers, but I'm not sure. What I see may be parts of paraphyses.
I saw no empty asci, either these are not mature or they are split, when spores are released.
I hope, that I can check this today on a better microscope than mine.

The round spores are from myxos. The small yellow about 7 and bigger brown ones about 13 micrometers.

I do not know N. minor, but I have this like N. niveus, very similar, identify by Alain Brissard and Zotto, and the apos macro look me very different.

Hi Marja

perhaps you cane keep the fungus in a moist box for some days t obtain mature spores?

Did you check IKI-reaction? Ascus tips should be blue. I also think it is Pseudohelotium pineti.
