Hyaloscypha britannica?

I found this species on decaying wood in Québec, Canada. I think it might be Hyaloscypha britannica. Would you agree with my identification?
-Apothecia are 0,2 to 0,5 mm

-Spores: 7–10.2 × 2.3–2.8 µm

-Asci 8 spored and IKI+

Here’s the iNat link with photos: https://www.inaturalist.ca/observations/301618959

Thanks for your help!

Re : Hyaloscypha britannica?

Hi Francois

the group is correct but I would prefer H. aureliella because of spore size. Both species were recently segregated in the genus Eupezizella.

Re : Hyaloscypha britannica?

I think H. britannica has a bit wider ascospores, so I think your collection could fit with H. aureliella

Zotto was (of course) faster than me :)

Re : Hyaloscypha britannica?

My database says H. britannica 7-12.5 x 2-3.2 and H. aureliella 5.3-10 x 1.8-3.2.

(both from Huhtinen 1990)

Re : Hyaloscypha britannica?

Great, so H. aureliella it is! Thanks to both of you, Zotto and Nicolas!
