Bonsoir.

Trouvé sur Populus tremula au sol.

Apo + KOH jaune.

Excipulum formé d'une couche de cellules rondes brun-noirâtre devenant ensuite hyalines. Sous hymenium de textura intricata.

Asques IKI+ b boucles+

Paraphyses larges de 2-3um cylindriques

spores avec souvent 1 cloison (parfois 2-3), mesurant 17,5-20,7 x 2,7-3,4 um

Poils sur l'excipulum hyalins cylindriques

Une idée ?

Re : Cf. Mollisia ?
Hi Yannick

Mollisia on wood with so long spores are rare. You have a photo of a mature living ascus? I assume the spores are nonseptate inside.

My folder "elegantior aff." has such long spores, but oil content is different andkOH is negative.

Hi Zotto.

No, unfortunatelly I didn't thought to take photo of mature living ascus. All I have are these ones.

In ascus, spores are unseptate, yes.

Do you agree with the genera of Mollisia ?

I will sequence it and may be we could see if this will help us.

Cheers.

Re : Cf. Mollisia ?
Mollisia of course! In a wide sense at least. DNA is a good idea, I am curious about it.
