                Hello,Yesterday I found these on burnt soil. Apoth

Dear collegues,
Tanja and me collected a Ciborinia species yesterday in the National Park hainich. It was by accident when turning logs for searching Corticiaceae. And it is only one fruitbody .....
I'm certain about the genus, but have no literature about it. Remarkable are the long spores, which are quite variable, but usually somewhat fusoid. Size is 13-16 x 5-6 µm. As far as I have seen they are completely empty.
Possible hosts are different decidous trees (Fagus, Carpinus, Acer, Fraxinus, Quercus) or the usual spring flowers in calcareous wet decidous forests: Allium ursinum, Ranunculus ficaria, Corydalis cava, ...
Has anyone an idea?
thank you and best regards,
Andreas
                Hello,
thanks to Marcel I have now some literature to that group. It seems very likely that it is Ciborinia whetzelii, occuring in leafes of Aspen, which was also present there.
Anyone has found this species already?
thank you, especially Marcel,
Andreas
                Also compare with this find of Patrice:
