yes, for sure! A quite rare species apparently.
Very well seen on your photo with IKI is the nasse apicale in the ascus apex, also known from typical Vibrissea species.
When did you collect this fungus? In summer?

I collected it the last spring (25 Aprill 2012 ..... 700 metres of altitude about... after copious rains)) in a deciduous forest (Quercus , Ostrya and so on...).

Interesting species, perhaps adapted to heavy rainfall in spring? I assume it was not on the bank of a rivulet, like Vibrissea?
the leaf was in a humid and shadowy place, but not on the bank of a rivulet.
