Merci pour votre aide.

Re : Cryptodiscus sp.
Hi Elisabeth,
the one-septate ascospores point towards C. foveolaris or C. pini, see here for more information: http://www.fungaldiversity.org/fdp/sfdp/FD38-3.pdf
Best wishes,
Gernot

Re : Cryptodiscus sp.
I have identified C. foveolaris about 50x, always on angiosperm branches. So I think this is C. pini, also based on the brownish colour.

Re : Cryptodiscus sp.
Baloch et al. mention a wide variety of hosts for C. foveolaris, including Pinus sylvestris:
"Substrate: on decorticated wood of deciduous trees (Betula sp., Corylus avellana, Populus tremula, Quercus sp., Salix caprea) and conifers (Picea abies, Pinus sylvestris)."
I also have two collections on Pinus sylvestris which I identified as C. foveolaris in my fungarium.
Cryptodiscus pini should have apothecia with dark brown margins which I can't really see on the photo. Maybe it's necessary to remove the bark to uncover them.
Best wishes,
Gernot

Re : Cryptodiscus sp.
O.k., Elisabeth Baloch's report on conifers I did not remember. C. pini is actually darker, with blackish margin, but my many phtos of C. foveolaris hae all a white margin. Elisabeth's samples has a light fox-brown margin. Also her spores are partly narrower than 2 µm and partly curved, both typical of pini. So what to conclude? Intermediate taxon?

Re : Cryptodiscus sp.
Yeah, I'm not sure either based on the information we have. Seems like a difficult case!

Re : Cryptodiscus sp.
Also ich kenne C. foveolaris zwar so nicht, oft war der irgendwie in eine Richtung verlängert, aber kommt auch rundlich vor. Die Hymeniumsfarbe, die von Carotinoid-Tröpfchen herrührt, würde aber in der Tat passen.

Re : Cryptodiscus sp.
Hallo in die Runde,
die Wirtsliste hier in der Region ist schon beachtlich: Acer, Cornus, Crataegus, Fagus, Fraxinus, Malus, Pinus, Prunus, Rosa, Salix, Taxus, Tilia, Syringa. In den letzten Jahren haben wir uns weniger um diese Art gekümmert, da käme bestimmt noch mehr zusammen.
Rundliche Apothezien hatten wir nicht so oft, überwiegend die von Zotto schon genannten langgezogenen.
Herzliche Grüße
Peter Püwert.
