is it var. leuconica or bulbopilosa?

Dear forum,

I found a few fruiting bodies on a dead twig of Myrica gale, partially decortated. Nearby grew several fruiting bodies of Incrucipulum sulphurellum

FRB: disc shaped, 237 x 191 µm, with long curling hairs

Spores: oblong: 5,56-8,1 x 1,89-3,29 µm Q= 2.93 with some drops at the poles
Asci: cylindrical, 23,64-28,83 x 3,37-5,44 µm in melzer apex slightly blue; no croziers
Paraphyses: filiform, sometimes forked: 26.57 x 2.43 µm
Hairs: thick walled, broad base and ending twisted like a corckscrew; 44,82 µm long, base 4.35 µm, wall: 1.91 µm

Thanks to this forum I think it is Hyaloscypha leuconia. I have no literature, can anyone help me to determine whether it is the var. leuconica or var. bulbopilosa?

Thanks in advance,

François Bartholomeeusen

In annex one picture of the curling hairs and one document

Re : is it var. leuconia or bulbopilosa?
Could be leuconica. H. cincinnata is a synonym of leuconica fide Huhtinen 1990, and that taxon was described with such corkscrew-hairs.

leuconica has rather thick-walled glassy hairs, it belongs genetically to Hyalopeziza and was even combined there.

Re : is it var. leuconica or bulbopilosa?
Thank you very much Zotto.
I compared my find with that of Enrique Rubio of 7/09/2014. At first glance it is the same but the dimensions are different. My measurements show a length of the hairs that does not come above 50 µm.



PS: I corrected leuconia in leuconica

Re : is it var. leuconica or bulbopilosa?
Yes, indeed, this is quite short. But the wall thickness of the hairs should be diagnostic. If thin-walled you have a typical hyaloscypha.
