Chers amis,Sur feuilles de Carex, trouvé une douzaine d'ex de ce champignon, 3-4-8mm de diam, avec un stipe qui peut dépasser le diam du chapeau.
Base du pied plus foncée, pied duveteux.
Spores avec goutellettes groupées et ou 2 plus grandes. 16-17 x 5 microns
Paraphyses bêtes, à peine élargies, qcfois ramifiées.
Excipulum à textura intricata?
Nous pensions à Rutstroemia calopus = paludosa de H O Baral.
Et vous?
Merci d'avance à ceux qui savent.

Re:Rutstroemia?...
The excipulum looks prismatic, not intricata. This is not untypical for R. paludosa/calopus. This species is somewhat variable, comprising also specimens with a gelatinized ectal excipulum. If you keep it fresh for some days, the spores will get 3-septate and globose conidia will develop on them.
Did you look at the ascus base? The asci are usually with croziers in this species, but last year I received a specimen on Typha: asci without croziers!
