Hy!I would ask for some help determing this specie
Sur tige pourrie d'ortie, en compagnie de Calloria urticae et Leptosphaeria acuta.a) spores uniseptées, étranglées : 15,5-17x5,5-6
b) conidies présentes
Je pense à Mycosphaerella superflua.
D'accord ?
Bernard
maybe, I am not sure, first it reminds me on Didymella sp., which also occurs on dead Urtica stems. I have a quite similar collection on Galium aparine which I had identified as D. exigua.
I guess M. superflua has smaller spores, like they are shown on Enrique's photos.

björn
Thank you for your answer! Does someone can show me photos of Enrique?
Big thank you in advance!
Bernard
I think Björn is referring to this page: http://www.ascofrance.fr/search_recolte/3477
Best wishes,
Gernot
For now, I do not see clear about the differences between the two species. I will check the size of the spores again.
For you, what would be the single most useful to separate the two species?
