Bonjour, Voici une planche de Sclerotinia récolt
It was found on the bark of a dead branch of Juniperus communis in Rotlia Naturreservat, Norway, in October last year, and I had no idea of what it was until I saw this tread: http://ascofrance.com/search_forum/43458
I think it must be a Scopinella, I have looked at the keys and read the info about it on the forum. I understand that it is only one species that has 4-spored asci(?), S. gallicola, but it is supposed to grow on Endocronartium harknessii. I did not observe it being fungicola, but it could grow on fungus under the bark or in the wood?
Peritecium: globose, 180µm
Neck: 570µm long
Spores: 6 [6.3 ; 6.5] 6.9 x 4.9 [5 ; 5.2] 5.3 µm, Q = 1.2 [1.24 ; 1.3] 1.4 ; N = 20 ; C = 68%, Me = 6.4 x 5.1 µm ; Qe = 1.3
Unfortunately it was only one ascocarp...
Thank you very much in advance

You may have an undescribed species of Scopinella. Only S. gallicola, growing on rust galls, has 4-spored asci. It is possible that S. gallicola, the only species described with 4-spored asci, is not restricted to rusts, but only careful study would be able to answer that question.
As far as I know, there has been only one new species added to the genus since Perz Piotr put his key to species on AscoFrance (http://www.ascofrance.fr/search_forum/8198). This new species, S. pyramidospora from grasses in Argentina, has 8-spored asci and ascospores having an unusual shape (Mycotaxon 122: 265–270. 2012.). It seems very close to S. caulincola. It is obviously not the same as yours.

I was thinking that it could possibly be an undescribed species. It is a pity that there is no more material, so that one could have made a proper description. I'll see if I can find more the next time I'm in Rotlia, but the chances are small.
Either way it will be presented in the report about Ascomycetes in Rotlia Nature Reserve that will be finished next year.
Thanks for thorough answer.

did you found this species again?
