Many spores had one to three tiny setulae.
Spore measurements:
(17.2) 17.22 - 18.7 (19.5) × (4.5) 4.53 - 4.9 (5.1) µm
Q = (3.4) 3.5 - 4.1 (4.3) ; N = 10
Me = 17.8 × 4.8 µm ; Qe = 3.7
This is clearly a Hymenoscyphus or something like that, but further I can't tell.

Re : Hymenoscyphus on Populus leaves
for me this looks like H. caudatus.

Re : Hymenoscyphus on Populus leaves
I searched some info and yes, that species (complex?) seems to fit! Thanks!

Re : Hymenoscyphus on Populus leaves
Not exactly, because of the croziers. The common H. caudatus is without, but this one is my folder "caudatus H+ central Europe Querc Popul leaves" and the nice name "Sophienpflege" is attached to most filenames. There is also the name albopunctus, but that species has smaller spores and lacks croziers.
Would be great to add a note on the collection site to your pics, including date.

Re : Hymenoscyphus on Populus leaves
I was actually earlier looking at that folder. I replaced the pics with ones that have the location and date added to them.
