Re : Discomycet on Fraxinus excelsior.
Dear Per,

you have a serious dirt problem in your microscope. Your camera focuses on the dirt and not on the object...

Best regards
Martin

Re : Discomycet on Fraxinus excelsior.
For a name we need more data, and you should also use water as medium in case your fungus was recently collected.
The asci have an apical ring. Did you test it with iodine, preferably Lugol?
The excipulum would be important too, and the paraphyses and their exudate. 
Your macro is so small that one could easily confuse a collapsed pyrenomycete for a discomycete.
