Trichopeziza mollissima sur Fallopia japonica

Bonsoir à tous,Trouvé récemment sur tige pourrissante de renouée du Japon ce que je pense être Trichopeziza mollissima.
a) poils cylindriques septés, couverts de granules/cristaux jaunes et asouvent arrondis
b) asques octosporés IKI+ : 67x5
c) paraphyses septées fusoïdes au sommet
d) spores fusiformes (immatures je pense : 10-12x2-3)
Quel est votre avis ?
Bernard

Moi qui imaginais que ce bel asco allait tout de suite trouver un nom, serais-je trop naïf ou inexpérimenté… ?

Re : Trichopeziza mollissima sur Fallopia japonica
This is a very difficult group now and I am far away to understand it. The spores are too short in my opinion for what I called mollissima which is now to be applied for the white one...
In any case important are the croziers in this aggregate, maybe also the colour reaction in Lgol (first blue then red).
The brown lumps on the hairs may be characteristic, but I am not sure.
Marketa Sandova works on this and I assume she could say more.

Salut Bernard
Je vois que tu remues beaucoup de renouée...
Aurais-tu une vue de l'espèce bien étalée où on voit l'hymenium.
Comme toi, je pense à T. mollissima.

Salut Gilbert,
Comme tu dis ! Et J'ai encore plusieurs ascos sur renouée du Japon qui vont arriver. Si les apothécies de celui-ci s'ouvrent je ne manquerai pas de refaire une photo !

Hi,
I have determined this kind of yellow Trichopezizas as T. leucophaea.
Naturally I'm not sure, weather my determination is correct.
There seems to be some mesh with this genus. I have found photos of yellow and white ones in internet as this species and as T. mollissima.

Hi Zotto,
I took the Trichopeziza and apothecia were opened. So I got more mature spores : 15-16x2,5

Moreover, I have observed the crozier at the base of asci.

Now I believe it is the normal frequent species that is currently fruiting in late spring and summer. Maybe the winter is so abnormal that it is now there.
Typical the drops in the paraphyses. And yes, croziers.
T. mollissima is a white species, according to the protologue, and probably specifically distinct from this one which might deserve a new name.
