THESE BLACKISH ASCOMATA WERE SEMI-IMMERSED IN A HARDWOOD BRANCH (PROBABLY QUERCUS) PARTIALLY BURIED IN THE GROUND, NEXT TO STROMATA OF XYLARIA HYPOXYLON. THE ASCOMATA, UP TO 700 MICRONS LONG, HAVE A BLACKISH PERITHECIAL VENTER IMMERSED UNDER THE WOOD AND A LONG NECK WITH A FIMBRIATED OSTIOLE THAT AGGLUTINATES SPORE BALLS OF DISCHARGED ASCOSPORES.THE ASCI ARE CYLINDRICAL, WITH A DOUBTFUL OR INCONSPICUOUS APICAL APPARATUS MLZ. NEGATIVE AND THEY HAVE EIGHT OBLIQUELY UNISERIATE ASCOSPORES. THE PARAPHYSES ARE ABUNDANT, IN SOME CASES WITH MONILIFORM SEGMENTS AND THEY EXCEED THE LEVEL OF THE ASCI.
THE MATURE ASCOSPORES ARE BLACISH BROWN, THEY HAVE AT LEAST ONE GERM PORE (RED ARROW), SOMETIMES TRANSVERSE SEPTA, A COMPLEX SYMMETRIY AND PERHAPS A SHORT GERM-SLIT ONLY WELL VISIBLE IN MELZER'S REAGENT (BLUE ARROW).
I CANNOT FIND AN APPROPRIATE GENUS FOR THIS FUNGUS, NOT EVEN WITHIN THE MELANOSPORALES, SO I AM ASKING FOR SOME CLUE TO SOLVE THIS ENIGMA.
I WOULD LIKE TO TAKE THIS OPPORTUNITY TO WISH YOU A HAPPY NEW YEAR.

Re : Enigmatic pyrenomycete
Hi Enrique,
Your fungus should not be too far from Bellojisia rhynchostoma.
Happy new year for you, and forum !

Hi Enrique,
Perhaps you have found Corylomyces selenospora.

Re : Enigmatic pyrenomycete
Some colleagues had initially pointed me towards Corylomyces and later towards Bellojisia. I think this fungus could belong to the latter genus, because by the morphology of the ascomata, the asci with an inconspicuous apical apparatus and the presence of abundant paraphyses. But the spores are quite different from those of J. rynchospora. Unfortunately there is too little material to attempt a culture and sequencing, but I am very grateful for your help.
