Re : INCONNU
Hi Alain
Compare with Phaeohelotium geogenum.
More specifically, check the IKI reaction should be positive.
In the event of uncertainty, use KOH first.
You should also check the presence of croziers.

Re : INCONNU
Hi Alain and Mirek
Yes, most often on Quercus remnants but rarely on other trees. IKI should stain a small ring, perhaps visible under oil immersion?
Very typical is that the spores contain large low-refractive vacuoles with a few minute LBs around, well visible on your photos.

Re : INCONNU
Merci à vous,
J'ai testé KOH avant IKI, pas de réaction, je vais recommencé l'essai.
OK pour crozier, je vais vérifier, j'ai encore du matériel bien frais.
Merci à vous deux,
Alian
