Asco sur tronc mort de sureau noir (Sambucus nigra)
Bernard CLESSE, 07-05-2023 21:24
Bernard CLESSEBonsoir à toutes et à tous,

Apparemment, je ne trouve pas cette espèce récoltée sur tronc mort de sureau noir (Sambucus nigra), dans les tomes de Björn Wergen.

Suis-je dans l'erreur ?

I don't have Björn's work but I imagine this is the common Melanomma pulvis-pyrius?

But of course, I should have thought of that, Zotto! In fact, I chose hyaline spores in the key while Björn Wergen chose "brown" spores which I still find really weird as a choice…

A very big thank you Zotto, for quickly putting a name to this banality...... :o)

Hello Bernard,
why not Melanomma pulvis-pyrius?
Yours, Lothar

Hi Lothar et Enrique,

Thank you very much for your messages ! 

I see it's not that simple...

I will read the article that Enrique shared which shows several taxa that are very close both macroscopically and microscopically and it is true that the ecology of Nigrograna fuscidula would fit well here.
