Dennisodiscus iridis?
Louis DENY, 09-05-2020 21:03
Bonjour.

Pas de macro, désolé. Petit (diametre max de 1mm) disque mollisoïde, sur tige de juncus effusus de l'an dernier, au bord d'un petit ruisseau. Spores séptées 4 fois (déjà dans l'asque) 37X2.5 µ, asques J+, apparemment 4 spores par asque. L=135µ, avec crochet.
En suivant la clé de Gminder j'arrive à Mollisia iridis.


1 Pouvez vous me confirmer si cette identification est correcte
2 j'ai trouvé différents noms de famille : Hemimollisia, Belonopsis, Dennisodiscus. s'agit-il bien de la même chose? Quel est celui qui prévaut aujourd'hui?
3 qu'est ce qui caractérise les Dennisiodiscus?


Merci pour votre aide

Re : Dennisodiscus iridis?
Cher Louis

yes, I think this is D. iridis. Important is that the living paraphyses do not contain long refractive vacuoles as Mollisia does. A character is also that the subiculum and medulla react blue in IKI, though not very striking and perhaps not always.

Hemimollisia was an idea of mine, a provisional new genus. Later I discovered that Dennisiodiscus could be the genus to place this species. But strong evidence is still lacking, especially a sequence.

The family is Ploettnerulaceae, where also Pyrenopeziza belongs, not Mollisiaceae.

Re : Dennisodiscus iridis?
Since I am planning to include this species, for which I had studies Le Gal's type, in my Dennisiodiscus paper, it may well be that I give a list of all verified records. Then it would be nice to mention also yours, with some data like location and when you collected it.
