Je présente une espèce présente dans le fruit de Alnus glutinosa.Je n'ai trouvé que des copies de l'image, il est difficile d'effectuer la microscopie mieux.
Asques Aporrincas amyloïdes. IKI +
Spores 15-18 microns, avec guttales.
Paraphyses avec VbS de nombreux.
Aide à la présente espèce, je pense Cudoniella, mais je pense que ce genre n'ont pas l'amyloïde Asques.
Merci pour votre aide

Hi Pablo
Cudoniella has also +/- amyloid asci. But your fungus seems to have slightly sculutoid spores. My guess is Hymenosc. caudatus The stipe is too long for H. imberbis. If you find more spores you could make more photos to show their shape perhaps better. Also I guess that te asci don't have croziers, unlike imberbis. - Oh, I overlooked you stated aporhynque.

Re:Cudoniella sur Alnus ?
Yesm that's good. I still believe this is O. caudatus. One might also consider H. fructigenus. I sometimes found such on Aolnus cones and it is very difficult to find a clear cut between these two species aggregates.
