récolte réalisée en plaine sur feuilles de saule en milieu humide. Apothécies 1-2 mm. Spores 16-19 x 3,6-4 µm. Asques 100-112 µm sans crochets
Merci d'avance pour vos avis.

Re : Asco sur feuilles de saule
Hi Patrice
do you also have spore photos under oil immersion?
I am not sure but I consider Phaeohelotium fulvidulum.
To be sure, the asci should arise from simple septa.
And whether the excipulum fits I am not sure. Is the left medulla or ectal?
A section would be better.

Re : Asco sur feuilles de saule
Hello Zotto and everyone,
sorry for my late answer. Here spores x 1000, following this new control, they measure 13-21 x 3,6-5 µm. I have not managed to make significant cuts to observe the flesh. Asci arise from simple septa.
I have already observed P. fulvidulum in a similar ecology, your idea is good.
Thank you very much Zotto.
Patrice

Re : Asco sur feuilles de saule
Yes, it may indeed be P. fulvidulum, though the spores and LBs are rather small.
