Yellow inoperculate on Frullania dilatata

I have sacrificed only one medium-sized apothecium, so no in-depth study. My impression is that there are not so many yellow inoperculates on Frullania. Suggestions appreciated.
Thanks.

Re : Yellow inoperculate on Frullania dilatata
As the spores are multiguttulate, Bryoscyphus turbinatus is excluded. So far I have no other idea. A pity that the elements are not alive, e.g. the paraphyses.

Re : Yellow inoperculate on Frullania dilatata
unfortunately one cannot see much on the micro-pictures. But macroscopically it reminds me a bit of "Luteodiscus" or however these fungi will be called. The spores are perhaps too large for this, but as I said before: one cannot see much ...

Re : Yellow inoperculate on Frullania dilatata
Good idea, Lothar! That should not be too difficult to check. A minute drop of 0.5-5% KOH on an apo should produce a pink colour when it is Luteodiscus.

Re : Yellow inoperculate on Frullania dilatata
I tried to take better photos of spores (in asci). Hope it helps a bit. This is the KOH treated apo microscoped in a drop of water after rinsing. Scale in these photos are 2.5 microns between lines. It fits quite well what you have called Luteodiscus pleurozii. It seems this is still a provisional name.

Re : Yellow inoperculate on Frullania dilatata
yes, Luteodiscus as well is a provisional name, too.

Re : Yellow inoperculate on Frullania dilatata
Hi Edvin
what did you do with your dirty microscope? Splendid photos! I can only agree with Luteodiscus bryophilus, as we cal it at the moment. My folders represent totally only 2 species so far, one with IKI blue and one with IKI red asci.
Now I would be glad if you send me collection data. We have numerous collections in the list and map but yours would add to the puzzle.
Zotto

Re : Yellow inoperculate on Frullania dilatata
Ha ha! You are right that the microscope may need a cleanup, but I guess the improvement is largely bacause I had some more time :-)
I will send you the collection data per email.
Thanks again to both of you.
