Hi.Here is the tiny white discomycete (~0.1 mm Ø) growing on dead branch of Salix (still attached), with Orbilia vinosa.
Asci 72-76 x 10 µm, without crozier, IKI-
Paraphyses filiform, 1.5-2 µm Ø, very flexuous.
Ascospores of heterogeneous shape, 10-15 x 3.5-4 µm
I have no idea of the genus...

Hi Nicolas
Are you sure no hairs? They can be very inconspicuous in Hyaloscypha in my experience.
Cheers

Re : Tiny white Helotiales
I can try a new mount to check that.

Hello,
Hyaloscypha minuta seems like good option. The hairs are not well developed there.

Here are two pictures of marginal cells (taken from the outside of an apothecium). No hairs or no hairs of Hyaloscypha-type.

Re : Tiny white Helotiales
How disappointing, I would have bet on it.
With this lack of characters I have no idea for a genus.
Cheers, Stip

Re : Tiny white Helotiales
I agree with H. minuta (= Parorbiliopsis minuta). That species has very minute hairs or not at all any.
But I estimate the diameter of the apos at max. 0.5 mm.
