Hello everybody,
I'm really at a loss with this one:
Stroma similar to Eutypa with cruciate Ostioles, but I keep finding hyaline spores with mostly 5 transversal and 1 (incomplete) longitudinal septum ?!?
Habitat: Deciduous wood, probably Fraxinus
Any ideas would be welcome!
Thanks and best wishes,
Stefan

Re : Stromatic Pyreno
Hello Stefan,
A possible genus might be Dothiora. Are the spores hyaline or cloured?
All the best,
Peter

Re : Stromatic Pyreno
Thanks Peter!
Spores are not obviously coloured, but might not be fully mature.
What I find about Dothiora is quite different from what I found.
Dothiora has well delimited, pulvinate stromata and no Perithecia (simple locules within the stroma).
