Bonsoir,Sur tige morte de plante, probablement d'Aruncus dioicus.
Massif du Jura, 10/06/2018, alt. : 1100 m.
Apothécies de 1-1,5 mm de diamètre, grégaires, sessiles, urcéolées puis cupuliformes, déformées par pression mutuelle. Hyménium brun-roux sombre. Marge et surface externe concolores mais couvertes d'épaisses franges de poils blancs.
Ascospores : 4,5-5,5 (7) x 1,4-1,6 (2)elliptiques, avec des guttules, OC 4, hyalines, lisses.
Asques : 20-25 x 4-4,5 µm, cylindriques, peu atténués à la base, à sommet non amyloïde, crochets+, inoperculés, contenant huit spores bisériées.
Paraphyses : filiformes, cylindriques, hyalines, larges de 1,5 µm.
Poils : 40-45 x 4-5 µm, à base élargie, a sommet aigu souvent couvert de cristaux.
Merci d'avance pour votre aide !

Re : Hyaloscyphaceae (?) sur tige morte
looks like Hyphodiscus, but without a clear section of the excipulum and hairs is difficult

Re : Hyaloscyphaceae (?) sur tige morte
Du coup pour le support il pourrait s'agir plutôt de Rubus idaeus...

Re : Hyaloscyphaceae (?) sur tige morte
Enrique Rubio me propose Trichopeziza viridula.
Ça colle parfaitement en ce qui concerne la microscopie.
Il y a en effet des teintes verdâtres au niveau de l'hyménium et de l'excipulum ectal.

Re : Hyaloscyphaceae (?) sur tige morte
Hi Andgelo
Trichopeziza viridula is not a bad idea. This viridula is an undescribed genus, but your species is not viridula, it is closely related. I think it is the same as in my folder "Ayel trichodea-like" in Hyphodiscus aff. (at the moment in Hyaloscyphaceae but possibly more correct in Cordieritidaceae).
Characteristic are the big oil drops in the spores.

Re : Hyaloscyphaceae (?) sur tige morte
Hi All,
Zotto, then I assume this in conspecific with my collections of aff. Hyphodiscus from Tenerife, is it? they were sent to Kadri to get sequences but I am still waiting
Best wishes,
Luis

Re : Hyaloscyphaceae (?) sur tige morte
Ah, you mean the one from 2008? This may be, but I am not always sure about conspecificiy when only the spore contents look similar.
Isn't it too old for sequences?

Re : Hyaloscyphaceae (?) sur tige morte
I do not think 10 years is too old! probably depend more on the sample and how it was preserved. Anyway, I can find it again when I come back to the Canary Island this Winter! If Kadri sends me the sequences I will tell you.

Re : Hyaloscyphaceae (?) sur tige morte
OK merci Zotto pour ton avis.
Erreur de ma part, pas fait attention au contenu des spores !
