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

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.

Greetings,

François 

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.
