I found this interesting yellowish asco growing on
I collected this ascomycete growing on wood unidentified. He did it in large groups.
Look at my bibliography and I think it can be Hyaloscypha aureliella. But I see that there is another species, H. Britannica, who is very similar and I doubt.
Can you help me identify it?
Thanks greetings
Susana

Hello Susana,
I think it is H. aureliella. H. britannica is quite similar but has larger spores.
Regards from Lothar
Attached from Zottos key (In vivo veritas):
12. Sp. 7-12(14)/2,4-3,3 µm, CRB-, H. 40-90(130) µm long.... H. britannica var. br.
12. Sp. 5-8(?10,5)/2,2-2,7 µm, surface CRB deep violet, H. 20-45(50) µm long (= H. stevensonii) ..................................... H. aureliella
I saw the key, but I've also seen in the folder of H. aureliella that the size of spores is bigger and maybe more closer to H.britannica.
Saludos
Susana
