It was found in November last year in Stange Norway on a decorticated dead standing stem of Corylus avellana.
Asci: ca. 100 x 7 µm
Spores (partspore?) rehydrated: (9.9) 10.5 - 12.6 (12.8) × (4.7) 4.8 - 5.4 (6.1) µm; Q = (1.9) 2 - 2.4 (2.7) ; N = 28; Me = 11.5 × 5.2 µm ; Qe = 2.2
Thanks in advance for any help.

Re : Pyreno on Corylus
Hi Per,
it sounds like a Synaptospora.
Cheers,
Jacques

Re : Pyreno on Corylus
Hi Jacques
Yes, I think it must be a Synaptospora! This genus consist of only 4 species and it may be S. petrakii. I have not been able to find pictures and description of it; if anybody has it I would be grateful to get it.
Thank you very much for help.

Re : Pyreno on Corylus
three papers dealing with Synaptospora species are available on Sydowia website.
Cain 1957, Huhndorf et al 1999 and Réblova 2002.
S. petrakii was described by Cain.

Re : Pyreno on Corylus
Hi Jacques
Thank you, I found these papers and these: Synaptospora setosa Huhndorf, F.A. Fern. & Cand., a rare Sordariomycete, Bernard DECLERCQ, 2011 and Helminthosphaeriaceae key in Miller et al. 2014.
I have studied these papers, but it do not fit the description of any of the 4 (5) Synaptospora species. The only one with 1-septate spores is S. olandica, but it is smaller and has different spores and smaller asci.
