The first 6 tables show surely one species with 2
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

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.
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
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.
Elsa
the substrate strongly looks after Betula. Here a few very old spores photos of Pseudovalsa lanciformis which I also favor.
Greetings Peter.
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-1863Â are very similar. Spores are within parameters and I see the vacuoles, so I think we reached the target.
Thank you all.
Regards
Elsa
