chers collègues,
trouvé sur tronc pourri de Picea abies en 1200 m sur mer.
spores approx. 16 x 7,5-8 µm, contenu completement par des guttules huileux dans la jeunesse, mais avec seulement une grand guttule dans les spores mature.
Je n'ai aucune idée .....
merci et amicalement,
Andreas

Salut Andreas,
Peut-être un lichen ?

Bonjour,
peut-être .... mais il n'y a pas des algues et aucune reaction amyloide.
amicalement,
Andreas

Hi Andreas
I also imagine that this is more apothecioid. Did you try a section?

Re : Pyreno ??
Ah, this section shows with the convex disc downwards. Inamyloid lichens are quite rare, but maybe. And some are non-lichenized :-) The dead asci with their wall thickening would be necessary for help from a lichenologist, I am quite sure.
