Je n'arrive pas à mettre un nom sur cette espèce trouvée sur la face sciée d'une branche de Pinus.
Apothécie maxi 1,4 mm sur subiculum (?) blanc, marge couverte de polis.
Asques 130 x 10 µ J+ faible, photo 1 avec IKI suivante aprés traitement KOH.
Paraphuses simples rarement forchues.
Poils de la marge hyalins jusqu'à 70 µ
Merci de votre aide.

Re : ASCOMYCÉTE INDÉTERMINÉ
Hello,
This is interesting. What are the measurements for spores? Also, not sure if I get the hair morphology right. They appear smooth and thin-walled but then there are some (hairs?) that are not smooth, and not that thin walled? Are the apos a bit over-mature perhaps?
The only Arachnopeziza with spores like that is A.aurata but it has more robust hairs if I remember right. But Pinus, that would something. This is sample/herbarium material! :-)

Re : ASCOMYCÉTE INDÉTERMINÉ
ok, that sound more like A. delicatula (spore measurements). But that doesnt match otherwise at all. There are some collections of A. "aurata" from Russia in Tarto (det. Ain Raitviir) from conifers. No sequences naturally. I do not have a good grasp on Arachnopeziza diversity on conifers. ---How would describe the ecology / substratum / locality in detail?
