Mlollisia cinerea?
Yatsiuk Iryna, 18-05-2011 15:24
Yatsiuk IrynaHello, forum!
I have recently collected this Mollisia on dead wood of Salix sp.
Spores 7-10*2-2,7 mkm, oil drops are not clearly visible. KOH-reaction negative, apical pore blued in iodine.
Asci 45-50 mkm.
Marginal cells one-septate, not very long.
Is it Mollisia cinerea or it can be something different?
Will be grateful for any help,
Irina

Re:Mlollisia cinerea?
Can be M. cinerea, but you need to show us the living spores with oil immersion, also asci and paraphyses. Good would also eb a section of the margin, perhaps also at the base. M. cinerea is not an easy species.

Re:Mlollisia cinerea?
For a Mollisia o.k., but I cannot surely exclude a Pyrenopeziza (that is only possible with living paraphyses).

But the characters you gave point to M. cinerea, at least s.l.

Thank you, Zotto!
I will attach spores and asci as soon as I can make photos of them. Today I'm not lucky in photography:(
Mollisia cinerea and everything within this complex is very unclear to me.

Hi Irina,
Did you try Andreas Gminder's key? http://www.mollisia.de/start.html
Despite the spores being a bit more narrow in your sample, I'd go for M. cinerea also. At lest s.l. as suggested by Zotto.

Re : Mlollisia cinerea?

Thank you, Luc!


I tried Gminder's key and got Mollisia cinerea sensu lato, but with no more accuracy within this complex.
