On Rhubarb

Seems, that determination is now just impossible for me.
Today I collected some seemingly Orbilias on rhubarb.
In microscope I saw hairs and they are visible in photos, too.
No Obbilia, but maybe some Unguiculella.

These are about 0,3-0,5 mm wide.
Spores are about 10-15x2-3 and asci 40-50x6-8, IKI-.
Paraphyses are narrow, swollen at the tips.
Hairs are about 30-40x3-4, pointed and seems glassy, but no reaction with KOH.

Raitviirs opus gave no answer to my problem: Marja

Re : On Rhubarb
Hyalopeziza raripila which I have in my Iridinea folder in Naevioideae. Asci may react red but are also negative.
