Rhopographus filicinus sur osmonde royale (Osmunda regalis) ??
Bernard CLESSE, 16-08-2015 20:19
Bernard CLESSEJe connais Rhopographus filicinus sur fougère-aigle (Pteridium aquilinum) mais ici c'est sur pétiole et rachis pourris d'osmonde royale (Osmunda regalis).

Je n'ai pas encore fait la micro mais savez-vous si Rhopographus filicinus vient aussi sur osmonde royale (Osmunda regalis) ?

Bonsoir Bernard
you need to show the spores / conidia; there are other fungi which occur on ferns and look a little like this. There is for example a "coelomycete" Leptostroma osmundicola, though I do not personally know that species. See http://www.librifungorum.org/Image.asp?ItemID=203&ImageFileName=001/0008b.jpg

Great thanks Chris !

I'll get the side of Leptostroma osmundicola and make a microscopy.

Best regards,

Bernard
