The spores were 45-50 um by 3-4 um.
See the following link.

Other observers in the Netherlands have found the same unknown species. See:

Does anyone has any idea?

Re : Unknown beheaded stubble lichen
I saw similar/same fungus recently, so I think I can help.
Look here https://doi.org/10.1139/b85-051
The best fit for your fungus seems Morrisographium boudieri.
Conidia from my collections often exceeded 50um so I decided for M. ulmi.

I think only M. boudieri is known from Europe, however I'm unsure of boundaries between these 2 species. Here are some pics https://drive.google.com/drive/folders/1a5WOxiTO_-fRC_ZTJqoL_CWG9EQta1Dg?usp=sharing
I saw it on Acer campestre and Cornus mas bark, what could be your substrate?

Re : Unknown beheaded stubble lichen
Thank you for you response.
It looks indeed rather similar. My substrate was willow.
The entire genus Morrisographium is until not found in the Netherlands, but these tiny fungus might easily be overlooked.
