Large Hymenoscyphus on herb stem

These long-stalked, 3-6 mm broad, rather bright orange-yellow apothecia (paler on the outside) were growing on a herb stem in a tall-herb spruce forest in Northern Norway. Not sure what herb, but the herb stem is marrow-filled.

Asci are IKI-. Paraphyses are very numerous and very distinctly multiguttulate. Spores measure typically 17-20 x 4-5 micr., with two tiny oil bodies near each end, becoming 1-septate. Some are germinating. Excipulum two-layered; a thick layer consisting of up to 25 micr. spherical or broadly oblong cells, and a thin layer of parallel rather thin hyphae.

I assume Hymenoscyphus s.l., a genus I am struggling with. But the asci are inamyloid, as far as I can see.

Opinions appreciated.

Thanks.

Re : Large Hymenoscyphus on herb stem
H. repandus has such spores but miuch larger. Inamyloidity sometimes occurs in amyloi taxa. Globose cells I wonder because stipitate taxa of Hymenoscyphus do not have that. But Hymenoscyphus is clear based on the paraphyses.

Re : Large Hymenoscyphus on herb stem
OK, thanks. I guess we cannot conclude, then?

Re : Large Hymenoscyphus on herb stem
I now agreed with Edvin that this should be Phaeohelotium epiphyllum, despite the long stipe.
