Robin PétermannBonjour,

Voici une probable Mollisia, genre que je n'ai pas vraiment osé aborder auparavant


Spores 8.5-10 (10.5) x 2.8-3.7 (4) ?m
Asques 40-65(79) x 4.5-7.5(11) ?m, aucune réaction dans le Lugol, pas de crochets
Paraphyses 38-54 x 3-4.5(6) ?m


Pas de réaction au KOH


Sur bois, très probablement de Fagus sylvatica


Avec la clé de Gminder, je tombe sur M.ligni mais je trouve que ça ne colle pas bien, les poils ne semblent pas assez foncés par exemple


Saignelégier JU CH 990m

Les photos sont ici https://www.inaturalist.org/observations/271298031

Re : Mollisia
Hi Robin,

Mollisia true, it is most of the time a genus in riddles.
Crochets I would defenitly say yes judging the photo's  and true this is not M. ligni, that species is brown haired.

Good luck!!!

Re : Mollisia
There are croziers indeed and the asci are in fact amyloid. I must've been too tired yesterday.

I uploaded a few better pictures in case someone would give a shot at further ID

Re : Mollisia
In earlier times I might have said M. bensesuada, but not today. The guttules in the spores exclude M. cinerea.

Re : Mollisia
Danke Zotto

Wenn ich richtig verstehe handelt es sich um ein Komplex, der sich (noch) nicht ohne Sequenzieren bestimmen lässt? 

Ich habe den Schlüssel von Gminder 2008, ich nutze die Gelegenheit um zu fragen, ob es einen rezenteren gibt?

Hallo Robin,

am besten versuchst du den Schlüssel von Ingo Wagner, der ist auf seinen Website:

Re : Mollisia
Hello Robin!

Your Mollisia belongs to a complex who was named at first benesuada in Zotto's "in vivo veritas".
But this species Pyrenopeziza/Mollisia benesuada is described with longer spores in original by Tulasne.


Because of this I named this species M. olivaceocinerea (Svrcek) based on the key of Andreas Gminder. I don't know if that was a good thing, but that's what I thought at the time.


It is a widespread but difficult taxon. Sequences show that these characteristics allow for different (relatively newly described) species, but I can't clearly distinguish them either microscopically or macroscopically.
This find looks like your's.

The two species, Mollisia oblonga and Mollisia nodosa, have a distance of about 3% between them (Zotto 2022), so they are clearly different species.
