Asco on stromata of Rhytisma salicinum

Hello againThis spring we have found this strange fungus, perhaps close to the genus Ciboria, growing on old stromata of Rhytisma salicinum on decaying leaves lying on the ground of Salix sp. at 1600 m of altitude. At the same place thay are many stromata with the ascomata of Rhytisma salicinum hanging on the branches of Salix.
This fungus was previously collected in another far place by our friend A. Román and was showed in Ascofrance http://www.ascofrance.com/search_forum/7900.
The ascospores are 2-nucleate, with polar dextrinoid bodys and late they seem to make sphaeric microconidia. Asci with apical pore of the Sclerotinia-type, with croziers. Medullary excipulum of textura intricata. Ectal excipulum globulosa, not blueing in IKI. The paraphyses have not conspicuous Vb's.
Have you any idea?
Thanks again

Re : Asco on stromata of Rhytisma salicinum
Very interesting!
On Salix leaves exist with a similar spore size:
Moellerodiscus rathenowiana
Sclerotinia foliicola (Cash & Davidson) Whetzel
Ciborinia wisconsiensis Batra
Not sure what Huhtinen 1985: 494 described as Ciborinia sp. from N-Quebec, on a flat sclerotium on salix leaves. Did he mistake the Rhytisma for a sclerotium??

Thanks Zotto
Do you know where Huhtinen descibed the Ciborinia on Salix leaves?

Re : Asco on stromata of Rhytisma salicinum
Yes! I wanted this paper. Thanks
Really it's very difficult to know if Huhtinen's fungus is the same because he draws roundish guttules at the poles (the mine have only small guttules) and the ectal excipulum is said built by a textura angularis whereas in our fungus is clearly globulosa.

Re : Asco on stromata of Rhytisma salicinum
I assume he studied in the dead state, so globulosa may turn to angularis and LBs fuse :-)

Yes. You are right. It's very possible
