Re : Pseudohelotium alaunae ? ou ?
By memory it could be, yes. I have no other idea.

Re : Pseudohelotium alaunae ? ou ?
Thank you so much.
In your records I see Parachnopeziza alaunae
Is this the current name?

Re : Pseudohelotium alaunae ? ou ?
Parachnopeziza is no more than an idea as I remember. The identity of the species seems also unclear as there exist two quite different sequences of this species, while the microscopy is similar. I have the species in my Parachnopeziza folder, where you can see that the cf. folder shows two finds in which the spores get up to 9-septate and produce conidia. Also the paraphyses are inconspicuously guttulate and curved, unlike typical alaunae.
