Hymenoscyphus
Yannick Mourgues, 31-08-2009 21:07
Yannick MourguesBonsoir.

J'aimerai votre avis sur cet Hymenoscyphus trouvé sur tiges mortes de Rubus.

Spores : 20x5 um environ bien qu'il n'y en avait que très peu. 1 cloison avec 2 guttules dans chaque partie. De forme "scutuloide".
Asques IKI+, 100-110x6-10 um, boucles +
paraphyses à sommet arrondi, septées, larges de 3-4 um, remplies de guttules réfringentes

Re:Hymenoscyphus
Hymenoscyphus calyculus serait un bon candidat. Non ?

Re:Hymenoscyphus
On Rubus I would not expect H. calyculus. Do you have a photo of the spores? Also the excipulum on the flanks should be consulted whether prismatica (calyculus) or globulosa (epiphyllus and relatives).

Re:Hymenoscyphus
No, I haven't any picture of spores because they were too rare and I wasn't able to make a picture.
I will see excipulum textura.

Re:Hymenoscyphus
Excipulum has a textura globulosa.
So, can we conclude Hymenoscyphus epiphyllus groups ?

Hymenoscyphus or Phaeohelotium ?

Re:Hymenoscyphus
Yes, you can say Phaeohelotium if one prefers to separate that genus. H. epiphyllus or H. monticola would be a choice. The multiguttulate paraphyses would tell for epiphyllus. Phaeohelotium do not have scutuloid spores, however. You cannot say which end of the spores is the upper end.
