Fimicolous pyrenomycete from southern Spain

Hi to everybodyI am surprised with these semi-inmersed perithecia growing in cow dung in southern Spain. There doesn't seem to be a well defined clypeus and the asci are neither amyloid nor dextrinoid, although they have an inconspicuous apical apparatus. The spores, surrounded by a wide gelatinous sheath after its expulsion from the asci, have no germ slits and they have a small caudal hyaline dwarf cell and an apical germinative pore.
In theory the closest genus should be Hypocopra, but there are many evidences and contradictions against this genus.
Do you have any idea that might help me?

Hola Enrique,
nice fungus and nice images. Indeed Hypocopra comes to mind first but I dion't think it is xylariaceous, perhaps just distantly related.
I wonder what would be the result of sequencing..
Good luck,
Jacques

Dear Jacques
I'm so glad to hear from you.
I guess this mushroom needs to be sequenced. I will keep you informed.
Thanks again.

Try Apodospora. I would be happy to sequence it if you send me a culture or the material.
Cheers,

Hello everyone!
Not at all certain that it is an Apodospora; normally this genus has only one germinating pore, but it seems on Enrique's pictures that the spores have two pores. Normally they also have a gelatinous envelope.

Excuse me, my message left too quickly, I meant for Apodospora, only one germinating pore and no hyaline cell at the base.
Michel.

Re : Fimicolous pyrenomycete from southern Spain
My feeling is that there's a basal dwarf cell and an apical germ pore. I don't think the basal structure can be a germ pore.
The gelatinous envelope of the spores is very broad and not as delimited as in Apodospora, but in principle I think this could be a suitable genus as Miller says.
But the material is very scarce and I have asked the collector to try to get more.
