Hello.A very tiny pyrenomycete sprouting sparsely
Hymenoscyphus

Bonsoir,Un bel Hymenoscyphus jaune sur tige morte herbacée. Jura, France, le 28-09-2018.
Spores : 28-34 x 4-5,5 µm, scutulées, garnies de gouttelettes, sans soie
Asques : cylindriques, à sommet amyloïde, avec crochet (?), contenant 8 spores bisériées.
Paraphyses : cylindriques, remplies de gouttelettes.
Il s'agit du groupe de H. scutula mais les spores très grandes me gènent.
Merci pour votre aide !
Andgelo

Re : Hymenoscyphus
Hi Andgelo
this requires in fact a clear image of the croziers. If they are present it is H. fucatus, if they are absent it is an unnamed species close to H. scutula or a long-spored variant of it.

Re : Hymenoscyphus
Oh this is ambiguous. The middle element is clearly without crozeirs. Left looks lke with but one septum could belong to a protubenance, although these usually do not break. Complete croziers are necessary to see in order to be sure.
Not clear what you men with tardive. Late in the year? H. fucatus was rarely collected. Hengstmengel 1996 says July-September, mainly on Polygonum.

Re : Hymenoscyphus
Right is protuberance. Left is unclear, it depends what is top and what bottom.

Re : Hymenoscyphus
Pour la photo de gauche, c'est la partie du haut qui appartient à l'asque.

Re : Hymenoscyphus
So I think the ascus points to the left, and then this is not a protuberance but a young branch that would lead to a further ascus. If this is true, it is again a proof for simple septate asci.

Re : Hymenoscyphus
Ok, pas de crochets donc. Il y avait beaucoup de bases d'asques simples mais je voulais m'assurer que les choses que je voyait n'étaient pas des crochets.
Sur ton google drive, y a un Hymenoscyphus aff. fucatus (H-) qui ressemble très bien à ma récolte.
