Bonjour à tous,Un petit coup de main pour identifier ce dicomycète s'il vous plait !Â
Asques à appareil apical I-, non bouclés, 45-50 x 6-7 µm, à contenu granuleux amyloïde lorsqu'immatures.
Paraphyses étroitement cylindriques.
Poils externes atténués-ventrus à paroi épaissie à l'apex.
Spores ellipsoïdes allongées 1-septées à maturité, germant dans l'hyménium, 8,5-11,1 x 3,0-3,65 µm ; Q = 2,7-3,3 (N = 26 dans l'eau).
Sur vieux Pyréno, sur Corylus avellana (sur la photo macro, on aperçoit de petits points blancs < 0,5 mm).
Herb. GC 17032602.
Merci !
Gilles

Re : Minuscule disco blanc sur Pyrénomycète
Hello,
Something close to Hyaloscypha/Olla is my first thought. How was it with the tip of the hairs, are they completely solid/glassy or thick walled (only)? Photos leave me uncertain and my french is very rusty... Maybe check Lugol/Melzer reaction with hairs and excipulum too.
Excipulum in itself looks characteristic too. I bet someone comes with a genera/species soon. Great! I shall keep on checking old pyrenos for something like this... really lovely!
