Hi to everybodyI'd like to know your opinion about
What can this be?
Piet BORMANS,

It looks a little bit like Acanthophiobolus helicosporus but it does not correspond with the spores.Ascomata: spherical 180 µm
Setae: black - 35 - 80 µm. Straight or slightly curved
Asci: 70 - 85 x 10 - 12 µm
Ascospores: filiform, 45 - 75 x 2 - 3 µm
Substrat: Calamagrostis epigejos
Thanks for your response

Hi Piet,
it reminds me on Chaetosphaeria spinosa. Maybe Andy and/or Sabine see your posting and comment...
A description of Ch.sp. is attached.
Cheers

Re : What can this be?
I'm trying to determine from the photos if the asci are unitunicate or bitunicate. If the latter, then I'm thinking this might be Acanthostigma scopulum.
Best,
Andy

Re : What can this be?
Hi Andy,
I would tend to see bitunicate asci (attached detail of Piet's photograph). At any rate no thin walled (unitunicate) as in Chaetospharia spinosa.
You are certainly right with Acanthostigma scopulum.
Best regards
Martin

Hi Andy,
We excluded Acanthostigma as we thought this adjacent genus was lignicolous. Does Acanthostigma occurs on monocotyls?

Re : What can this be?
I really do not know, but I suspect that many saprobic pyrenos and loculos are not that substrate specific. I have even found Cercophora scortea on wood in USA, although it is known from dung in Europe.

Re : What can this be?
what about Taphrophila (Acanthostigmina, Ophiobolus, Tubeufia) trichella? This fungus occurs on graminaceous hosts. How many septa do the spores have?

Re : What can this be?
Dear Walter,
Excellent proposal. Taphrophila trichella was described by the belgian mycologists Bommer & Rousseau who collected it on Ammophila at the Belgian coast. And Calamagrostis is mentioned in literature as another substrate. It would be great to have collected this species once again in our country after more than 120 years.
Allez Piet, check the number of septa. We did not see coiled ascospores in the ascus but that is maybe not that important.

Re : What can this be?
Dear all,
I have tried to take a photo, to show you the number of septa. I counted from 6 to 9 septa. It was not easy for me. I am still looking for the ideal method. Here is the result.

Re : What can this be?
in this case it may be Taphrophila hebridensis (Dennis) Réblová & M.E. Barr
