Hypocreales (maybe) on bark of Acer pseudoplatanus

I have tried to find a name for this species with long multiseptate ascospores and have failed so far. I have tried Hypocreales, Tubeufia, various Ostropales... The spores measure up to about 55 x 5 µm, the ascomata do not collapse and become translucent but don't change colour in KOH. Any suggestions gratefully received.

Merry Christmas and a happy and productive year to all!

Paul

Hi Paul,

I think your fungus is Xanthonectria pseudopeziza (Desm.) Lechat, J. Fourn. & P.-A. Moreau. I attach the PDF.

Merry Christmas
