Hi all, Could anyone give me an idea what this could be?
Thanks, Gerrit
On fallen branch of Salix. Apothecia diam 0.3-0.4 (0.5) mm, sessile.
Ascus contains 8 spores, iodine positive, 69-66 x 9-10 ?m, croziers present.
Paraphyses cylindrical width 2-3.5 ?m.
Spores non septate, 7-16.5 x 2-3.5 ?m; Qav.=4.4; n=15; spores taken from apothecium in Congo red in 5% ammonia.
have you checked to see if there is a KOH reaction?
regards
Chris
The apothecium turns yellowish greenish in 5% KOH.
Gerrit
Also: could you take the size of spores just in water? In Congo read, that will disturb the measures. Check also if the spores aren't septate now and then.
Looking at the spores in water is absolutely necessary, because NH4OH and KOH can influence the number and look of the guttules.
Then, take Andreas Gminder's key: http://www.mollisia.de/Word_Dokumente/key.doc
Cheers - LUC.
I measured the spores in water 12.7 x 2.9 um.
Thanks for the link to Andreas Gminders Mollisia key. With your help and the key I quickly arrived at Mollisia fusca.
Problem solved, thanks again.
Regards, Gerrit
