Helotiaceae?
Yatsiuk Iryna, 06-12-2010 16:57
Yatsiuk IrynaHello, everybody
Recently I have found a small white stalked discomycete on the bark of most likely Quercus robur.
Spores: 6,4-7,6*1,6-2,3 um
Asci: 43-49*2,7-4 um, with croziers
Pore blued in IKI
Marginal hairs 5-6 septate, 70-80 um in length.
Paraphyses were incrusted with small granules.
What it can be? Thank you very much for any help.

Re:Helotiaceae?
Hi Irina

with your data it is difficult to name a genus. First, are the apothecia white? What diameter?
The hairs are hyaline? Important: are the hairs actually smooth?
The granules of the paraphyses are surely inside. I assume you looked at the fresh specimen?

Oh, I did not see the photo before. They are a bit dried as it seems. You can spray with water to get them more opened.

Maybe a Lachnum, but then the hairs are distinctly rough.

I sprayed them with water.
Maybe hairs on my picture are just hyphae of some fungicolous fungus, now I see, that they are not on every fruit body.

Re:Helotiaceae?
Yes, so they look better :-)
I assume a Lachnum (or Dasyscyphella). Depends on how the hairs look a like.

Re:Helotiaceae?
Thanks a lot one more time, for your help!
And one more question - is there some special literature on these two genera?

Re:Helotiaceae?
Yes, I attach here a recent paper dealing with Dasyscyphella and others. Marketa also wrote one on Lachnum but it seems I do not have a pdf of it.

Re:Helotiaceae?
Perhaps one of the following...
Trechopeziza mollissima
Trechopeziza sulphurea
Albotricha acutipila
Lachnellula willkommii

Zotto,
Thank you for the paper, I'll take a closer look at hairs.
