HI Elisabeth

Look for Calycellina triseptata on Athyrium

Re : Sur fougère

I wonder about the similarity between C. triseptata and my Mollisina triseptata. Both have the very same features, except for simple hairs in C. triseptata and shorter, Mollisina-protuberances in the latter. Did you see any hairs near the margin?

here the description by Raschle 1979.

Re : Sur fougère

Hi Zotto. After wiewing your pics, really, they seems to be the same thing

Re : Sur fougère

Merci pour vos avis Enrique & Zotto,

Voici des photos de la marge, il y a des poils, mais plutôt difficile à faire une belle photo!

Re : Sur fougère

I think it's Mollisina on the last pick i see minute protuberances. maybe you will see more clearly when staining in Congo red.

see attach. The protuberances are difficult to see but they are there. If Raschle is right, C. triseptata must be a different species. maybe the apical ring is not hemiamyloid there, we cannot know.
