Lophiostomataceae on Ambrosia

Some time ago Joseba Castillo asked us about a pyrenomycete found on roots of Ambrosia artemisiifolia (Asteraceae). The pseudothecia are more or less spherical, immersed, with an superficial apical papilla often laterally compressed. The asci are bitunicate and the spores hyaline or subhyaline, with several transverse septa, with a larger cell and a conspicuous gelatinous sheath clearly visible in dilute India ink. From all this it looks like a member of the family Lophiostomataceae. Do you have any ideas that might help us.Many thanks in advance

Re : Lophiostomataceae on Ambrosia
Hola Enrique, no entiendo mucho de estas, pero la morfología esporal, la vaina gelatinosa que envuelve a la espora y la materia interascal que creo apreciar en la cuarta imágen, seguramente voy a decir una tontería, así que no me hagas mucho caso, pero me recuerdan a Amniculicola.
Un abrazo.
Un abrazo.

Re : Lophiostomataceae on Ambrosia
Thank you very much Josep.
I have never been able to study any Amniculicola species, but it seems to be a genus of freshwater pyrenomycetes characterised by their fusiform, hyaline, two-celled ascospores, constricted at the median septum, surrounded by an irregular hyaline gelatinous sheath. And these characters do not match those of this collection.
