Nectria-like fungus on herbaceous stems

Hi to allThis fungus was collected at Somiedo (1350 m) on herbaceous stems, perhaps of Umbelliferae. It makes subepidermial orange perithecia KOH negative 0.2-0.4 mm, with only the obtuse papilla raising the periderm of the host. I think they are glabrous, the hairs we can see maybe belong to the stem host.
The ascospores are smooth, 1-septate, with conspicuous large lipid content. The asci have a conspicuous, refractive, cianophilou, Melzer negative apical apparatus.
Have you some idea? Could be a Nectriella species?
Many thanks in advance

Re : Nectria-like fungus on herbaceous stems
Hi Enrique,
I think you are right, it is Nectriella dacrymycella (Nyl.) Rehm
All the best,
Christian

Hi Christian
Many thanks again
Are common these large LBs in the ascospores?
