Hymenoscyphus

Yannick MourguesHi.

Here is probably Hymenoscyphus sp. (near repandus ?) I have found on the Aubrac (48), France, on dead stems of grasses, on boggy ground.

Apothecia cream to pale ochraceous, reddening when damaged, up to 4mm diameter and 3,5 mm high, stalked.
Asci 85-90x8-9 µm, very faintly blue in IKI., arising from croziers.
Spores fusiform to sub-cylindrical, aseptate, 13-16(18)x5-6 µm, OCI = 3-4.
Paraphyses filled with refractive guttules.

What do you think about this specie ?

Thank's a lot for your help !

Re:Hymenoscyphus
Il s'agit sans doute d'un Ombrophila !

Re:Hymenoscyphus
Oui, ou peut-être un Cudoniella mais le contenu sporal dessiné par Yannick me paraît trop important pour ce dernier genre.
Est-ce que l'anneau apical (coloré par l'iode) est visible jusqu'à l'apex ou pas ?

Re:Hymenoscyphus
Bonjour.
Pour répondre à Nicolas, l'anneau apical n'est que très difficilement visible et ne va pas jusqu'à l'apex.

Re:Hymenoscyphus
Bonjour Yannick,

I do agree with René that it looks very much like Ombrophila, you should check the inner excipulum if it is gelatinized and perhaps contains calcium crystals. It is not O. ambigua.

Re:Hymenoscyphus
Merci à tous.
Je vais chercher dans les Ombrophila.
Thank's too Stip !
