Re : Identification specie with brown phragmospores
J'oubliais : spores avec enveloppe gelatineuse.
Deux photos dans l'encre de Chine : spores matures et immatures.

Toujours aucune idée ?

Re : Identification specie with brown phragmospores
Hi Yannick,

now I am first with the answer: did you try Montagnula or Massariosphaeria? I had a similar species on Rubus fructicosus with smaller spores, which is also still indeterminable. I think your species looks more like a Montagnula, but I did not see this one before...

regards,
björn

A Strange specie...
