Re : Big spores
Hi Per,

the substrate looks like Acer campestre, probably Massaria inquinans.

Greetings Peter.

Re : Big spores

Hi,


Peter's proposal is probably  good, but you can't "get a name", as you said, without more informations, concerning the fungus, and concerning the host. Please read "Molecular data reveal high host specificity in the phylogenetically isolated genus Massaria (Ascomycota, Massariaceae) Hermann Voglmayr & Walter M. Jaklitsch" * and you'll understand what is a good determination of Massaria.


Alain


* I can send you the paper if necessary

Re : Big spores
After reading the paper on Massaria I have found out that it is Massaria platanoidea, as you also have concluded. Thank you. It has only been found once in Norway.
