Orange ostioles on Populus tremula bark

we are looking for ideas regarding this pyrenomycetoid fungus with orange to red ostioles, collected on bark of Populus tremula. It is very distinctive, so I hope that someone might recognise it.
Thank you and best wishes,
Gernot

Re : Orange ostioles on Populus tremula bark
It looks quite a bit like Byssosphaeria. Could be Byssosphaeria rhodomphala that has seen better days. Or something similar.

Re : Orange ostioles on Populus tremula bark
Thank you for your suggestion, Ethan. Byssosphaeria was my first thought, but I don't know any species that fits well. Byssosphaeria rhodomphala is described with brown ascospores, in this specimen they are hyaline.
Best wishes,
Gernot
