Bernard CLESSESur 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 ?

Hi,

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.

regards,
björn

Hi Bernard,

I think Björn is referring to this page: http://www.ascofrance.fr/search_recolte/3477

Re : Asco sur Urtica2
Big thank you to both Björn and Gernot for your help.

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?
