Re : Hymenoscyphys sp (?)
I think the ascus has croziers but is it really inamyloid? Did you test with Lugol? It may be that the apical ring reacts red (hemiamyloid), so in MLZ you get a negative reaction.
Important is to study in fresh living state, e.g. are the spores biguttulate in vivo or is this an artifact by confluence of small LBs? Paraphysis contents and excipulum are necessary too.
Did you found this fungus in autumn?

Re : Hymenoscyphys sp (?)
Bon après-midi. En effet, cela a été collecté en automne. Malheureusement, lorsque j'ai effectué les préparations, je n'avais pas de lugol (ni beaucoup d'expérience avec le microscope). Je vais essayer d'améliorer les informations pour les futurs messages. Merci pour les suggestions.
