Botryotinia spec.
Zoltan Lukacs, 20-11-2013 22:05
Zoltan LukacsDear Friends,

an interesting record on sandy soil near Tortula ruralis.  The sclerotium is gelatinosus. My friend thinks, this is Botryotinia spec.  Spores: 15(17-22)25x6(6,5-8)9µm


Best wishes


Zoltan

Re : Botryotinia spec.
Hi Zoltan

looks very interesting, but this needs good microphotos of living asci and paraphyses, and freshly ejected spores . The contents of the paraphyses are important. Do you have it still fresh?

Re : Botryotinia spec.
This is very good! You see that 4 spores are distinctly smaller than the other. So I am quite sure you have Sclerotinia trifoliorum.
