Tiny white Helotiales
Nicolas VAN VOOREN, 26-10-2020 09:58
Nicolas VAN VOORENHi.
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...

Re : Tiny white Helotiales
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.

Re : Tiny white Helotiales
Hello,

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

Re : Tiny white Helotiales
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.
