At a loss: Coprotus ochraceus????

Asci narrowly cylindric and long: 200-218 x 11-15. Croziers +, IKI -. Paraphyses about the same length, enlarged apex up to 6µ. Rather hyaline to my suprise, just a little pale yellowish.
Excipulum textura angularis-globulosa.
Spores quite large, av 20,9 x 10, Q=2,08. Narrowly ellipsoid, smooth, hyaline and cyanophilous. Normally I see de Bary bubbles clearly but this time not quite so. I think they have them, but am not sure? Eliminating a lot, the only thing that comes close as far as I can see is Coprotus ochraceus. But some features differ (a bit) from literature: size of spores, paraphyses and length of asci.
What do you think? Again: thanks in advance!
Greetings, Maria

Hello Maria.
I am not sure that your mushroom is a Coprotus, moreover it does not seem ripe enough. Maybe you could wait a little longer so that you can also make a preparation in the Cotton Blue with ejected spores.
Michel.

Hello Michel,
First: thanks for your help! I am an absolute amateur in mycology, but I have seen de Bary bubbles: they are visible even in the asci. I include a photo of a released spore in CB: no de Bary bubble to be seen. So it must be a clear visible nucleus that I see, but not a de Bary bubble.
I am really absolutely at a loss with this one: it's not Cheilymenia, not Byssonectria, not Lasiobolus, I don't think its Thecotheus .... This is a bright yellow asco, quite large, taking forever to 'ripe'. The photo of the spores I included earlier was from one ripe ascocarp.
Do you have an idea of what it could be?
Greetings, Maria

Bonsoir.
Yes, myco is not always obvious and it is not uncommon to find species that cause problems.
Your last photo of spores in the blue seems to show a yellowish reaction inside that could point to Cheilymenia.
I think you still have to wait for more maturity. It is in no way a Lasiobolus or a Thecotheus.
Michel.
