Bernard CLESSEUne idée de nom pour ce Cistella trouvé sur pétiole pourri de fougère-aigle (Pteridium aquilinum) ?

Merci d'avance !

I imagine this is Cistella pteridialis but it is not very different from C. grevillei, which has very similar hairs and spores.

Bonjour Bernard et Zotto, 
From Bernard's images and data, I am not sure to see distinctive characters with  C. grevillei ( which seems a complex and found on many sorts of plants) but for the substrate of course. 

Is C. pteridialis a now published combination or still a provisional one for Dasyscyphus pteridialis ? 

Thanks to you both
AmitiésMichel

Re : Cistella sur Pteridium aquilinum
You are right, that combination does not exist. That group requires a genetic study. C. grevillei often reacts IKI-bluish in the medulla or ectal, but not always.
