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.

Regards,
Björn

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.

Decaisnella mesascium, obviously. Where did you find it, 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.

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.
