Parorbiliopsis spec.?

yesterday we found a small salmon coloured tiny ascomycete on an attached branch of Salix. I was certain to have found an Orbilia, but to my surprise the microscopy revealed something totally different.
I at first even wondered if this could be an operculate ascomycete, but am quite convinced that it is inoperculate.
Asci appr. 100 x 14,5 µm, with croziers (or being pleurorhynch), IKI negative
Spores appr. 15,5 x 7,5 µm, with many medium sized and small oil drops, in IKI with two big glycogen deposites, becoming one-septate when germinating
Paraphyses filiform, septate, once or twice branched and often somewhat curved, some with an amorphes mass at the tip
Excipulum of a kind of textura angularis with quite massive cell walls, giving it an appearance of a gelatinous texture.
Growing on attached branch of Salix caprea, together with Hyalorbilia juliae and Lecanidion atratum, Goslar, Göttingerode, östl. Langenberg, 15.01.2020
Any suggestions very welcome :-)
all the best, Andreas and Sylvie

Re : Parorbiliopsis spec.?
Hi Andreas & Sylvie
I conclude you mean ca. 0.5 mm diam. (some people say small for 5 mm).
This is clearly Helotium uvidulum, a species that I have placed in my Laetinaevia folder although the sequence we have does not cluster with L. carneoflavida. Whether it would cluster with L. lapponica, the type species of Laetinaevia, is unclear because of lack of a sequence.
This species is quite frequent and may occur together with Orbiliaceae. Its name uvidulum (= hydrophilous) is strange but I studied the type.

Re : Parorbiliopsis spec.?
Dear Zotto
thanks a lot! I have not heared from this species before and wouldn't have searched in Letinaevia.
And yes, small in this case meant 0,3 mm :-)
all the best,
Andreas
