Thank you, Zuzana

Re : Hymenoscyphus vacini
Hello Zuzana,
I would determine this the same way, I sometimes find this on leaves of Acer pseudoplatanus. Was ist A. pseudoplatanus, too?
Surely Zotto will also write - I hope he will agree :-)
Yours, Lothar

Re : Hymenoscyphus vacini
Fully agreed. Very characteristic is the net of brown cortical hyphae on the excipulum. Also the growth on sceletonized leaves.

Re : Hymenoscyphus vacini
Hi Lothar and Zotto,
many thanks to both of you!
Yes, the substrate was Acer pseudoplatanus and the fungus grew in incredible amounts in the locality - there were thousands and thousands of apothecia.
Best regards,
Zuzana

Re : Hymenoscyphus vacini
There is only one unpublished sequence (ITS), from HB 9590, which has no match in GenBank, even for an environmental sequence of that species.
