Pyrenopeziza/Pirottaea from Italian Alps

(sub)alpine rivulet, on decaying wet stems of dicotylous herb. The spores are poor in oil (0-1) and about 14-18(20)/3,5-4 µm large. Asci mostly more than 60 µm, with croziers, IKI blue(ish). Paraphyses without vacuolar body and with weakly contrastive guttules. Excipulum dark globulosa with darker "grana" (Pirottaea-like), with hyaline clavate end-cells.In Pirottaea I find no match, and in Pyrenopeziza I end at P. millegrana that should grow on Filipendula (what the substrate isn`t).
Who has a better idea?
Best regards, Lothar

P. millegrana has a high lipid content. Pirottaea is clear, if accepting the genus. Are there never acute hairs? I recommend to measure more, e.g. are the asci 10 µm wide?

Hello Zotto,
thanks for your comment. I think I will have to re-examine the specimen. Maybe I will post again later.
