I found this pyreno on falling branch but I'm sure about the tree.
Spores are not initially septate, I saw few irregulary septate (5?)
(28) 33.9 - 38.7 (40.5) × (11.9) 12 - 13 (14.1) µm
Would appreciate any help.
Thank you
Elsa

Re : Help on this pyreno
Hello Elsa.
This is a lichen; We can see the apothecia lecanorines. I do not know if you will be able to have a precise answer here, but maybe you could propose your photos on a site corresponding to your search.
Michel.

Re : Help on this pyreno
Bonsoir,
Ici les photos ne sont pas au "top", ceci ne facilite pas la tâche. Cependant s'il y bien un lichen sur le support,les asques et les spores représentés ne sont pas de cet organisme. Il s'agit bien de spores et asques d'un champignon et apparemment d'une Diaporthale. J'oserais même avancer : Pseudovalsa lanciformis. A confirmer
Cordialement
Paul

Re : Help on this pyreno
Thank you guys, sorry for the photos, but that's what I have by now.
There is a lichen here Michel, but I sampled just the black pyreno in the middle.
Like Paul said the micro of this lichen wouldn't be like this, I'm going to search about Pseudovalsa, thanks for the tip.

Hi all,
the substrate strongly looks after Betula. Here a few very old spores photos of Pseudovalsa lanciformis which I also favor.
Greetings Peter.

Re : Help on this pyreno
Thank you Peter, for the photo signaling.
In fact it's probably Betula, there were many there where I collected. Macro photos of Pseudovalsa lanciformis like these https://www.sites.google.com/site/funghiparadise/d---ascomycota-sordariomycetes/diaporthales---kugelpilze/pseudovalsaceae/pseudovalsa-lanciformis-fr-ces-de-not-1863 are very similar. Spores are within parameters and I see the vacuoles, so I think we reached the target.
Thank you all.
Regards
Elsa
