Pyrenomycete on wet hardwood

Enrique RubioHello friends of the forum. I would like to know your opinion about these scattered perithecia growing on semirotten and very wet wood of Populus, who were neither half-submerged in water nor near a river. The (sub) superficial blackish ostiolate peritecia up to 300 microns in diameter, more or less carbonaceous, pyriform, papilate but no beaked, glabrous. Asci long cylindrical, 8-spored, with a long attenuated base, 165-200 x 10-11, with a thick refractive, Melzer negative, apical annulus. Paraphyses filiform. Ascospores hyaline, mostly with 5 eusepta.
No anamorph I have seen. In a way it seems to remind me of a species of the genus Chaetosphaeria (Ch. cupulifera), but the ring of the asci seems excessively large, as does its length.
Do you have some idea for this collection?
Thanks again
