Hyaloscypha cf

Petra EimannHello everyone,
I am literally stumped by this find. I hope that I can get help here to identify it. The find is from 19.03.2022, found on bark (spruce?) Preparation in KOH slightly yellowish discoloured, spore size on average 11.05 x 3.72 / Q=2.99, hook+ IKI+ I suspect that it is a Hyaloscypha, but cannot find a suitable species.

Hi,

Did you observe any amyloid "nodules" in the excipulum? Similar as in Eupezizella aureliella. Your collection appears to have yellow exudate around the hairs. You could compare to Eupezizella britannica.

And once on it, you could also compare to Resinoscypha variepilosa (previously Protounguicularia/Arachnopeziza). Or to Mimicoscypha (lacrimiformis?). These are often on conifers as well. Especially R. variepilosa.

The hairs remind me of Resinoscypha, but the very dark basal excipulum I dont recall. Yes, Hyaloscyphaceae, but indeed not a Hyaloscypha!

Difficult for me to say with this docu of dead material.

I am reminded of Psilocistella quercina, what about this?

Quijada et al. 2014 Psilocistella quercina AscomyceteOrg 06-05 143-146

But I wonder about the greybrown basal excipulum

Hi,

thank you very much for the advice. There are no amyloid "nodules" in the excipulum.
The fruiting bodies are on the bark of freshly cut spruce. They have developed after a few weeks in a damp chamber. Maybe some characteristics are different from "normally" grown fruiting bodies. I will study all the clues and hope to come to a conclusion. Thank you again.
