Bonnes nuits.
Aide pour commencer.

J'ai trouvé cette espèce dans des bois de Betula, beaucoup d'exemplaires, blancs et avec des cheveux.
Asca amiliode J +.

Je pense qu'il peut être Trichopeziza, Mollisia...
Plus tard je mettrai une certaine image micro

Merci

Re:Aide pour commencer

Hi Pablo

please try KOH to the water mount of this Mollisia and view if the hymenium extrudes a yellow sap for some seconds. Did you use Lugol and was it blue?

Re:Aide pour commencer

Yes, you can use NaOH as well. Let's say min. 1 %, better 3-5. A section through the apo would be good, from base to margin, e.g. to see the hairs.

Spores seem eguttulate, what size?

Re:Aide pour commencer

Hello,

Yellow reaction of himenio to NaOH

Esporas 8-12 x 3 microns.
Ascas 50-58 x 5-8 microns.
round hairs in the apex, and also long, attempt to observe apical of long hairs.

I do not observe clearly gutulas, I observe points in the poles of espora, but I do not know clearly. in the photo the unique thing is not watched well… but. .es that I can now with micro broken.

thanks.

Pablo
