Yellow Calycellina (?) on Fagus leaves
Enrique Rubio, 28-09-2016 20:38
Enrique Rubio

Hi to everybody


I need again your help with these yellow, shortly stipitate, ascomata up to 1 mm, found on Fagus sylvatica leaves on calcareous soil at 1200 m. The asci are 8-spored, IKI rb Calycina-type, arising from croziers . Paraphyses and marginal cells with yellow refractive VBs as the marginal cells from the flanks. Excipulum with any textura porrecta.


I don't find any species that matches well with my collection.


Have you some idea for me?


Thanks again

Re : Yellow Calycellina (?) on Fagus leaves
Hmmm, very strange! Could you please send me in high resolution?
The guttulate paraphyses and thin-walled excipulum forbids an Allophylaria, the former also a Calycellina. I am without an idea :-(

Hi Zotto


I think this is not an Allophylaria. The excipulum is absolutely different....

Re : Yellow Calycellina (?) on Fagus leaves

Hi Enrique,


I think it is not a Calycellina, in this genus most species have (sub)sessile apothecia, as well as the content of the paraphyses is mostly a longitudinal vacuolar body.


In spite of the apical apparatus I see no difference to a Hymenoscyphus which has usually stipitate apothecia and guttulate paraphyses. In your foto the apical apparatus looks like Calycina type. Is it really?


Best regards from Lothar

Re : Yellow Calycellina (?) on Fagus leaves
Hi Lothar
you are right with the contents of the paraphyses, but the apical ring is decidedly of the Allophylaria type. I presume a relationship with that genus, but would not expect that it belongs to it.
Look here

Re : Yellow Calycellina (?) on Fagus leaves
Yes, Zotto. You are right because the apical pore is not of the Calycina-type but the Allophylaria-type. But you could see the excipulum does not belong absolutely to this genus.

Re : Yellow Calycellina (?) on Fagus leaves
The limits between these two ring types are not sharp, but this case is quite clear. Surely the Allophylaria type is not restricted to Allophylaria, like in the Calycina type.
