Growing on a thiny branch of Pterospartum tridentatum (Genista tridentata). Minute white turbinate apothecia 125-375 microns in diam. with fineley downy margins. Hymenium reddening with the age. Asci arising from croziers, apical pore of the Calycina-type, IKI bb. Excipulum of a dense textura oblita with longitudinaly oriented narrow hyphae with obtuse end cells plenty of refractive VBs.Do you have some idea?
Thanks again.

Re : White Calycina on Pterospartum
Looks a bit like C. populina, but I am not sure.

Re : White Calycina on Pterospartum
Hi Zotto
The morphological characters are quite similar, and in fact I had thought of this possibility. But I was distanced from it by the fact of growing in lignified substrate and not in leaves. However, I have a possible collection of Calycina populina on Fagus cupules.
Thank you again

Re : White Calycina on Pterospartum
I was thinking that Pterospartum with its small size and winng-like stems is a bit leaf-like. And indeed in my home forest occurred the leaf-inhabiting H. caudatus and H. syringaecolor on Fagus cupules.

Re : White Calycina on Pterospartum
Yes, it is possible that you are right, although in this case the fruitbodys were born in lignified zones and not in the peculiar modified stems of the plant.
