Asco Growing on Kindbergia praelonga = Eurhynchium praelongum Moss

I have found some whitish fruit bodies growing gregariously on the green petioles of Kindbergia praelonga = Eurhynchium praelongum moss.
The is probably a pyrenomycete and perhaps from the Hypocreales.
I have attached images of the fruit bodies, spores and asci, extended end cells / hairs and hyaline, septate attachment hyphae. The spores typically measure 32.5 - 40 x 7 - 7.5 um and are consistently 1-septate with large guttules in each cell.
I have found nothing resembling the macroscopic and microscopic characteristics of this species in mycological literature and nothing in Ascofrance either. I assume that it is parasitic on bryophytes.
I wonder if anyone has any ideas?
Thank You,
With Best Wishes,
Peter.

Hi Peter,
sorry to answer so late but we had some problems with hackers on the site ascofrance.
I don't know what is your fungus, did you test KOH and lactic acid?. Besides it would be necessary to see a vertical section through ascomatal wall. Are the ascospore smooth or ornamented? you should observe them in coton blue to see a possible ornamentation.
Good luke,
Christian

Hello Christian,
Thank you for your reply.
I did monitor this forum posting until the the hacking problem and then forgot about it, until I was reminded on Friday.
My fruit bodies are not in the best of condition now, but I have taken microphotos of the excipulum and a spore in cotton blue. The spores look smooth, but I think that they are faintly longitudinally striated.
I have also photographed the ostiole and some hyaline hairs or end cells adjacent to it.
The photos are attached.
I don't know whether these help to shed any light on the identity.
With Best Wishes,
Peter.
