Hallo Forum,I think to have found M. cinerea but I have doubts because of the septated spores IN the asci.
The species grew on a wet, rotten and decorticated piece of wood of Populus sp.
Reaction in IKI 1-3 and Lugol: negative.
Reaction in Meltzer: asci apically blue and parafphyses jellowing
No margin hairs found
Spores 9.69x2.55um; one-septated; without oildrops
Asci with one-septated spores
Cinerea or 'atlantica'?
Thanks for any suggestion.
William

Re : Mollisia cinerea?
Do you have a figure of septate spores in the asci? Not too small to properly seeing it? In M. atlantica the living asci contain septate spores, this is important.
M. atlantica I remember more grey with blackish-brown exterior, not bluish.
Your Lugol must be too diluted (old). But IKI 1-3 means blue?

Re : Mollisia cinerea?
Hallo Otto,
thx for your reaction.
I insert here a picture of the septated spores in the fresh asci.
The underside of the ascocarps is really blackish.
My Lugol could be indeed too old as well as the IKI I bought in Belgium (the label on the flask sais 'Liquide de Baral (IKI 1-3)'). Only the Melzer reagens provoques some reaction as shown on the pictures.
Regards,
William

Re : Mollisia cinerea?
Yes, now I see it. It is not fully clear whether this ascus is turgescent, but at least maybe it was before squashing. If you saw this repeatedly, it may be M. atlantica. We do not have this species in southern Germany, personally I only know it from England.

Re : Mollisia cinerea?
I have a lot of material here, Otto.
Now I prepared a new sporee and tomorrow I wil look again at the asci to have the ultimate prove.
And if you wish I could send you a sample (w.slosse@telenet.be)
Thx, Otto.

Re : Mollisia cinerea?
Could we conclude based on following photos of septated spores in the asci it concerns M.atlantica?
