Bonjour,Peut-être Mollisia palustris ?
Trouvée sur tige de Phragmites, tout en bas, quasiment dans l'eau.
Fructifications 0,5-1,5 mm, sessiles et appliquées contre le substrat, gris-brun, marge claire. Elles jaunissent fortement dans le KOH. Spores petites 5-7 x 1-1,5- µm, incurvées, guttulées aux extrémités. Asques 30-40 x 3-5 µm, J+, avec crochet ( ?). Paraphyses : plus ou moins de même longueur et assez larges, avec de nombreuses vacuoles très réfringentes. Excipulum extal : textura globosa. Présence de poils brun septés et issus de l'excipulum ectal.
Merci de donner votre avis.
François

Re : Mollisia sp.
Typical Mollisia caricina, except that this could be heterogeneous and your find would be M. phragmitis. See article by Gminder 2006 in Czech Mycol.

Re : Mollisia sp.
Do you think it would be useful to sequence it?

Re : Mollisia sp.
I am indeed glad about such a question. M. caricina/phragmitis is a problem to be solved. At the mnoment (no, it is 3.5 years ago) we know the following: Typha has a special clade very distant from Phalaris and Festuca. So it seems probable that Phragmites is in the latter clade and M. phragmitis comprises Poaceae while M. caricina is restricted to Cyperaceae and Typhaceae. But this is a bit speculative.

Re : Mollisia sp.
I put it out to dry and we're going to sequence it.

Re : Mollisia sp.
I found what I assume is the same mollisia, aslso on Phragmites, with a strong posotive reaction with KOH, minute spores needle shape (5-8X1.2-1.5), sometimes curves, OCI 0-1 (one small guttule at each end) and asci 30-40 long with croziers.

Re : Mollisia sp.
Yes, earlier I said M. caricina but now I say M. phragmitis, believing that Cyperaceae have M. caricina.
