Good eveningThese small, amphora-shaped perithecia
Karstenia? anamoph?

Spore measured in water: 50 × 3 µm
When making a slide, orange strings containing many anamorphic spores emerged from beneath these craters.
Conidia measured in water: 6.7 - 7.5 × 1.6 - 1.9µm, Q = 3.6 - 4.6
Could this be the anamorph of K. idaei? We haven't found any anamorphs of Karstenia idaei in Ellis&Ellis or online.
Thank you in advance for your help,
Geert&Margot

Re : Karstenia? anamoph?
I don`t think so. Look better in the vicinity of Valsa and Leucostoma.

Re : Karstenia? anamoph?
the tiny black spots could be an Eutypella quaternata with its orange anamorph Libertella faginea.
Though the septate conidia look more like a Fusarium. Maybe another contamination...

Re : Karstenia? anamoph?
Thanks to both of you for the replies.
We'll continue our search and see if we can find asci.

Martin: The orange strands emerged from under the white perithecia when I poked them. We also initially thought it was Eutypella quaternata, which we've seen before, but we couldn't place it with the white discs.
