There are croziers indeed and the asci are in fact amyloid. I must've been too tired yesterday.

I uploaded a few better pictures in case someone would give a shot at further ID

In earlier times I might have said M. bensesuada, but not today. The guttules in the spores exclude M. cinerea.

Danke Zotto

Wenn ich richtig verstehe handelt es sich um ein Komplex, der sich (noch) nicht ohne Sequenzieren bestimmen lässt? 

Ich habe den Schlüssel von Gminder 2008, ich nutze die Gelegenheit um zu fragen, ob es einen rezenteren gibt?

Hello Robin!

Your Mollisia belongs to a complex who was named at first benesuada in Zotto's "in vivo veritas".
But this species Pyrenopeziza/Mollisia benesuada is described with longer spores in original by Tulasne.

Because of this I named this species M. olivaceocinerea (Svrcek) based on the key of Andreas Gminder. I don't know if that was a good thing, but that's what I thought at the time.

It is a widespread but difficult taxon. Sequences show that these characteristics allow for different (relatively newly described) species, but I can't clearly distinguish them either microscopically or macroscopically.
This find looks like your's.

The two species, Mollisia oblonga and Mollisia nodosa, have a distance of about 3% between them (Zotto 2022), so they are clearly different species.
