Patrice TANCHAUDBonsoir, récolte à proximité du milieu dunaire
Can anyone give me some advice on this Hyaloscyphaceae?
It grows abundant on a Populus log.
Macro: See Photo. Size up to around 1 mm in diam.
Micro: Asci 50-60 x 5-6 µm, hooked, porus IKI blue. Spores mostly slightly clavate, 9-10.5 x 2.8-3.5 µm. Paraphyses nearly cylindrical, 1.5 µm diameter, abundant and rather adhesive to each other. Margin with hairs. These are hyaline, thin to slightly thick-walled, cylindrical, mostly naked, agglutinated, 2-3 µm in diameter. For more details see photos.
Thank you for any help
Stefan

Yes, there were small warts at the apices of some hairs! And from a first quick search, Cistella dentata seems to fit with most microcharacters.
Thanks a lot!
