Sporocarps very small, therefore macro photos from under the microscope.
Has two types of hair.
Marginal, long without content.
At the bottom of the fruiting body shorter but with contents in the upper part, visible in both H2O and Lugol.
I have no idea again.

Olla transiens.
--Bernard Clesse made a collection (in 2018 I think) of species that had very weakly glassy hair tips. Looked more like a Hyaloscypha. It turned out to be Olla aff. transiens. But somewhat different genetically. But this one looks like a straightforward transiens.

Hi Timo
Because of this characteristic hair, I was looking through "Olla" folder yesterday on the Zotto disc but found nothing. Only the "SPAIN" collection was somewhat similar but had much narrower spores.
Thank you and best regards

Re : Small ASCO on Populus wood?
check Protounguicularia transiens. ...but Olla is the correct name :-)

Re : Small ASCO on Populus wood?
I agree, but I think Olla is not the correct name. At the moment I have the species in the Hyaloscypha folder, because the phylogenetic support for this species is with Hyaloscypha leuconica. However, that species was transferred to Hyalopeziza based on genetics from Japanese samples. Oddly enough, the similar H. leuc. var. bulbopilosa clustered with Hyaloscypha (also from Japan). I have no European data to verify this, perhaps Timo has.

...but it is indeed a somewhat messy spot in the Helotiales systematics.
