Tiny, pale grey inoperculate discomycete on Quercus leaf - Denmark

With Incrucipulum piliare but this much bigger.
hyper tiny; pale grey with dark brown base. Spores 13,2 x 2 µm, curved, mostly 2-celled, rarely 4-celled. Parafyses with VB's. I+bbb

suggestions highly welcome :-)

Re : Tiny, pale grey inoperculate discomycete on Quercus leaf - Denmark
Hello Thomas,
it would be interesting to know something about the excipulum - is it a brownish textura globulosa? If yes, I would think of a Mollisia (you describe and show vacuolar bodies in the paraphyses). On oak leafes I only know M. nervicola which has smaller spores (always?). 
That`s all I can contribute.
Yours, Lothar

Reminds me a bit of Calycellina fagina on Fagus, but that would have a distinct scutum and I need living cells to see clearer. There are actually elongated VBs in the paraphyses, I think I saw them.

Re : Tiny, pale grey inoperculate discomycete on Quercus leaf - Denmark
yes that was my first thought too but the elongte VBs look mollisioid and the scutuloid remnants are mor Calycellina like, I should list this for myself as a Calycellina spec.

cheers,

Stip
