Micropeziza sp. on Phalaris arundinacea

Bonjour touscollected recently on Phalaris lying in a wet place with Polytrichum moss nearby. This is surely a Micropeziza; looking at Zotto's images I am uncertain of which Micropeziza it can be assigned to: M. karstenii or cornea - I suspect some confusion over types? but I may well be wrong. Asci were IKI BB, and croziers were present. The paraphyses varied from ones with greenish yellow apical contents - like those in HB5565 (see the last attached image here, right side), to ones in which a much longer apical portion (almost half) contained a rich amber pigment (see the sixth image).
I am keeping the material damp as, annoyingly, I am having difficulties finding ripe spores, although the material is abundant. NB All the images are of living material mounted in water.

Re : Micropeziza sp. on Phalaris arundinacea
Hi Chris
wonderful that you find this species as we are just dealing with this genus. The exudate on the exterior is abundant as in Crustomollisia. I do not find a difference between M. cornea (on sedges) and karstenii (on Poaceae) and even M. poae.
A correction: Tose paraphyses with rich amber pigment are dead ones. Also the ascus and the spores within are dead, regrettably.

Re : Micropeziza sp. on Phalaris arundinacea
Many thanks for the fast response Zotto; yes I was amused when I looked at this "Crustomollisia-like" discomycete under the microscope;-)!
We had several dry weeks here and then a period of heavy rain, so these appeared quite fresh, but were clearly not. I visit the site regularly so I should be able to get fresher apothecia.
nochmals vielen Dank
