Re : Hymenoscyphus macroguttatus??
Looks like Rutstroemia, possibly R. henningsiana/paludosa (not sure about croziers).

Re : Hymenoscyphus macroguttatus??
Hola Nihad,las estructuras del excipulo no parecen de rutstroemia.

Re : Hymenoscyphus macroguttatus??
Yes it is rutstroemiaceous from the apical ring shape. Croziers seem to be absent, so R. henningsiana/paludosa would be the choice (now Clarireedia). But the host looks like Equisetum?

Re : Hymenoscyphus macroguttatus??
Hi Ruiz, 

The IKI reaction shows a Sclerotiniaceae-type one rather than Heliotiaceae. (Which excludes Hymenoscyphus) The ectal is not Globulosa so Rutstroemiaceae seems more appropriate
May be another preparation with a different angle in the excipulum would show a more Rustroemiacea-like ectal . 
My guess is the same as Zotto's, depending on presence or not of croziers, in the genera Clareeridia. 
Amitiés
Michel
