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

Re : Pyreno ??

Salut Andreas,


Peut-être un lichen ?

Bonjour,


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


amicalement,
Andreas

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

Re : Pyreno ??

Hello Zotto,


I did, but am not satisfied with the result ....


But I have observed that at least some of the apothecia are sitting on a mat of algae - so it is quite possible that this is a lichen, unfortunately ;-)


thanks and best regards,
Andreas

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.
