Re : Hymenoscyphus??
This is a Rutstroemiaceae, R. paludosa (or the earlier name henningsiana which might be the same).

Characterized by occurring on Cyperaceae and asci lacking croziers, also no stroma visible.

With a narrow genus concept one could adopt Clarireedia for those  monocots inhabiting species.

Bonjour Alessandro,


welcome to Ascofrance (unless I overlooked a previous post ?)


Nice pictures ! Did you compare your collection to Rutstroemia paludosa ?


Amitiés. Michel

Re : Hymenoscyphus??
Bonjour,

R. paludosa : base asques sans crochet. Différent de R. calopus qui a la base des asques avec crochet ?

Re : Hymenoscyphus??

Oui Patrice, comme déjà signalé sur Ascofrance,


par exemple : http://www.ascofrance.fr/search_forum/52696


Mais pas certain que ce soit aussi simple , je crois me souvenir avoir lu un signalement d un calopus sans crochets ...


Michel

Re : Hymenoscyphus??
OK, merci Michel.
Patrice TANCHAUD, 15-07-2019 10:10
Re : Hymenoscyphus??
Mais alors Michel, ta récolte de R. calopus sans crochet ne pourrait pas être R. maritima ?
Hans-Otto Baral, 15-07-2019 10:24

Re : Hymenoscyphus??
R. maritima is difficult. The whole group is a complex, only a sequencing project correlated with morphological documentation would bring us forward.

Re : Hymenoscyphus??
Yes, I understand. Thanks Zotto.
