Hello Daniele,

I fear the dead structures (stained in ?) you show are not sufficient to say too much about your discomycete. First of all, I miss any information about the excipulum.

I would guess that the excipulum contained of round cells with dark pigment and the living paraphyses contained an elongated vacuolar body. If this is right it would be a species of Mollisia. But then, the determination job only begins ...

Things you surely need are for instance: reaction of the porus with IKI (likely euamyloid), reaction with KOH (yellow or not), contents of the living spores (pattern of guttules) and presence of croziers (likely yes). With all this information, you will get closer to the aim ...
