Nectria-like fungus on herbaceous stems
Enrique Rubio, 25-04-2017 20:54
Enrique RubioHi to all
This 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

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?

yes Enrique, there are usually many droplets in the ascospores
