Bryoscyphus dicrani?

I am a biology student from Belgium and one month ago I started trying to identify ascomycetes.
I found this cool specie and I am pretty sure it's Bryoscyphus dicrani. The spores are +- 15-18 x 6,8µm and I don't see any guttules. It would be nice if I could get a second opnion because maybe there are some species that I don't know exist.

Re : Bryoscyphus dicrani?
Welcome!
I am not sure if your fungus is helotialean or perhaps a member of Pezizales.
Did you try iodine (Lugol)?
I recommend to use oil immersion for the spore contents. It is good that you used water as preparation medium.
Perhaps you can show us also the paraphyses?

Re : Bryoscyphus dicrani?
Thanks for the fast reply!
I don't have iodine at home, what is the advantage of using that? My microscope doesn't have the 100x lens so I can't work with immersion oil.
I tried to make a photo of the paraphyses but I don't know if it is usefull (not the best quality), it looks like they have a widening at the top. I think it grows on the moss, which is also a characteristic for Bryoscyphus dicrani.

Re : Bryoscyphus dicrani?
The spores are so regularly ellipsoid that I suppose an operculate disco, but I am not sure. Iodine often stains the ascus in blue, and very differently between the two large groups.
The paraphyses could fit a Pezizales.
