Hello, a few days ago I have collected a Macroconi
Pyrenopeziza/Mollisia on stems of Impatiens

Hi,Please about help with determination of this collection.
Found on the dead stems of Impatiens glandulifera in the Czech Republic, 2. 9. 2021.
Marginal cells 16 x 5,5 um, excipular cells 13-15 x 10-12,5 um, dark brown. Asci IKI(+?), 35-40 X 5-7 um, paraphyses 30 x 1,8 um. Ascospores fusoid, hyaline, OCI=0-1, 7-9(9,5) x 1,7-2,5 um, Q=3,5, Me=8 x 2,3 um. KOH reaction of excipulum negative.
Any idea?? Thanks.

Re : Pyrenopeziza/Mollisia on stems of Impatiens
To me this looks like a Mollisia. The crucial KOH reaction refers to the hymenium. Did you study living paraphyses? Herewith you can distinguish Pyrenopeziza which has no VBs (refractive vacuoles). To suggest a species name is difficult. M. revincta has a yellow KOH-reaction

The your methods are not appropriate
- water as mountant
- don't apply pressure on the cover slip when studying sections and only very slight pressure for squash mounts.
