Croziers present, IKI+, paraphyses full of tiny VBs. Spores naviculiform, measuring 18.7 - 19.7 × 4.2 - 5 µm.
Any idea what the species is?

Re : Hymenoscyphys on Typha
Although there is no doubt I would appreciate a photo of an immature dead ascus in IKI to see the Hymenoscyphus-type of ring. The excipulum is probably of prismatic cells?
The spores appear to be almost non-scutuloid. My guess is Hymenoscyphus macroguttatus.
Torsten Richter has a Hymenoscyphus typhae nom. prov. but that has short stalks and wider spores with often 1-2 septa inside the living asci. It is in the varicosporoides folder of Cudoniella (HB 10115). Excipulum alsmost globose, so a totally different species.

Re : Hymenoscyphys on Typha
Thanks again! I checked your H. macroguttatus folder, and that seems to fit pretty well. Yeah, these stalks are fairly long and there were no septas in the spores, but it's good to be aware of that H. typhae species. The excipulum seems to be of textura prismatica.

Re : Hymenoscyphys on Typha
The ring looks a bit thick, anyway I have little doubt. Yes, prismatic.
