J'aimerais connaître une opinion sur cette espèce de Leptosphaeria (Phaeosphaeria) qui croît sur des tiges d'Ammophila arenaria. Les spores, avec 5 (4) septa, mesurent 25-30 x 7.J'ai pensé qu'il pourrait s'agir de Leptosphaeria larseniana Munk.
Merci à tous

Might he be Leptospharia larseniana Munk?
Thanks to all

Re:Leptosphaeria (Phaeosphaeria)
Certaines ostioles me paraissent allongées sur la photo ? Je penserais à un Lophiostoma. caulium par exemple qui doit avoir 5 cloisons. Mais ce n'est qu'une idée vague peut-être basée sur une illusion d'optique !

Re:Leptosphaeria (Phaeosphaeria)
Try Phaeosphaeria vagans, where spores sometimes lack vertical septa, occuring on Ammophila.

Re:Leptosphaeria (Phaeosphaeria)
Des amis Bernard et Robert :
Mes ascomata, semiimmergés, possèdent des papilles allogées, parfois latéralement comprimés, mais dans les cellules des spores je ne vois pas des vertical septa. Est-ce que cela peut succéder dans Phaeospharia vagans ? .
Merci par votre amicale aide

Dear friends,
I think that is : Lophiostoma caudatum Fabre
Best wishes, :)

Re:Leptosphaeria (Phaeosphaeria)
Dear all,
as far as Erique explained us that the ascomata have flattened ostiola, we have to look indeed in to one of following genera: Lophiostoma, Lophiotrema, Massariosphaeria. The problem here is, and taht is the reason why I sent no further comments, that species known to me are guttulate and I did not observe guttulae on the photo. I thought the L. caudatum spores are more "caudate" than what we see here but Chesters & Bell (1970) already mentioned that several forms occur which got in the past distinct names. I do not know if some more recent study gave us better insight on this "complex". So I think for the moment being that Christian gave us the right answer.
Best regards,
Bernard Declercq
