Mollisia on Fagus
Enrique Rubio, 14-05-2019 19:46
Enrique RubioThese small, gregarious apothecia up to 0.5 mm in diameter grew on a branch of Fagus sylvatica fallen to the ground at 1300 m altitude. At the beginning they are whitish, but step by step they are invading of gray or amber gray color from the base.
The asci have croziers and the apical pore is IKI b . The margin is not overflowing and it is made by hyaline clavate cells with vacuolar bodys. The paraphyses contain vacuoles sometimes abundant, sometimes refractive, sometimes not, so the content is not clearly that of a Mollisia.
KOH negative or almost negative. I think it's a Mollisia, perhaps related to the amberina/ subamberina/sublivbidula group, but the asci IKI b seem to separate it from this complex.
What do you think?

Hi Enrique
your idea of sublividula seems pretty good, you earlier had similar samples.

Can you send me the pics by mail? And do you have a photo in IKI? I want to see the amyloid reaction.

Re : Mollisia on Fagus
Hi Zotto
Now I send you the photos by mail
Sorry, I forgot to attach photos of the apical pore in IKI, which is small and although difficult to see is clearly amyloid. I hope it can be seen in the photos. Unlike other collections of this complex with pore IKI negative, this is IKI positive.

Re : Mollisia on Fagus
Indeed it is! So we do not now if this is another species or variability.

I was afraid of that answer.
Thank you again, Zotto

Re : Mollisia on Fagus
All these well-documented samples should be sequenced. There are so many sequences without or with only brief docu.

Yes. I'll do it, and I'll keep informed you.
