Hyaloscypha bulbopilossa?

Sur fagus ce petit disque blanc translucide, à l'aspect d'une hyaloscypha.
asques 45 X 7 µ, J+, crochet +
spores régulières 8-9 X 2.5, une petite guttule à chaque extrémité
poils jusqu'à 150µ, lisses, septés, à base souvent enflée
structure primatique
Tout semblait 'coller' avec Hyaloscypha leuconica var. bulbosa, mais il me semble que les poils des hyaloscyphae ne sont pas séptés.
Du coup je ne sais plus.
Merci

Re : Hyaloscypha bulbopilossa?
Cher Luis
your pics clearly show hairs with a solid glassy tip.
This is Olla transiens, and the asci are in fact simple-septate, though with a basal protuberance. True croziers you will not find.

Re : Hyaloscypha bulbopilossa?
Thank you Zotto.
This question of presence of crozier or not, is definitively a difficulty!

Re : Hyaloscypha bulbopilossa?
Croziers can only definitely be clarified when the basal cell is still adherent, and the direction of view suitable.
