Re : Pyreno on Fraxinus excelsior.
Per, can you tell me where did you find it? In which country, next village. Perhaps you can check if the substrate is Fraxinus excelsior.

Re : Pyreno on Fraxinus excelsior.
It was found in Norway, Tønsberg, 11.03.2011, on a living tree, at a graveyeard.
Most of the trees are Fraxinus excelsior, but that is not 100 % sure.

Re : Pyreno on Fraxinus excelsior.
I visited the site to-day and found it again, after 6 years at the same, old, tree. It is Fraxinus excelsior. I took some new photos of fresh fungi.

Re : Pyreno on Fraxinus excelsior.
Hi all,
before longer time I had published the following photos here as Pleospora spec. However, the inquiry was not considered farther and later I have determined the mushroom than Strickeria macrosperma Fuckel (WINTER, 1887: Die Pilze Deutschlands, Österreichs und der Schweiz. II. Abteilung). The mushroom seems to be identical with the species named now. It was found on Fraxinus.
Greetings Peter.

Re : Pyreno on Fraxinus excelsior.
Da muß ich erst bei einem Pilzfreund nachfragen, er bat mich um die Bestimmung. Es war vor ungefähr zwei Jahren im Hessischen.
Grüße Peter.

Re : Pyreno on Fraxinus excelsior.
Hi all,
Rather common on Fraxinus excelsior (>10 personnal records), I also find it on Acer pseudoplatanus.

Re : Pyreno on Fraxinus excelsior.
Hi all,
a few days ago I was able to determine the species, found on malus bark.
Greetings Peter.
