Asco sur tige pourrie de Juncus acutiflorus
Bernard CLESSE, 29-09-2016 10:12
Bernard CLESSEBonjour à tous,

Voici un asco sur tige pourrie de jonc à tépales aigus (Juncus acutiflorus) trouvé en pessière-boulaie tourbeuse à sphaignes.

a) asques IKI+, probablement à crochet à la base
b) spores fusiformes à cylindriques-fusiformes, souvent arquées, à microguttules, uniseptées à maturité : 9-13x2,5

Re : Asco sur tige pourrie de Juncus acutiflorus
No idea. The excipulum would be important. Paraphyses and their contents? No hairs?

Re : Asco sur tige pourrie de Juncus acutiflorus
I'll check paraphyses, excipulum and hairs this afternoon. Thank you Zotto.

Couldn't it be a Mollisia? There are several on Juncus.
Paraphyses would be important, indeed.

Regards
Martin

Re : Asco sur tige pourrie de Juncus acutiflorus
Good evening Zotto and Martin,

Sorry for the delay...


I checked paraphyses : they are cylindrical, septate, without content or refractive guttules


And there are a few hairs, subulate.

Do you have an idea ?

This must be a Hyaloscypha.

OK Zotto, thank you!

I imagine since it's hard to go further ...

Re : Asco sur tige pourrie de Juncus acutiflorus

hello,


Hyaloscypha fuckelii var fuckelii (Crozier+) is reported from Juncus stems. Even the sporesize might fit (measures in monograph are of dead spores). H. secalina might work, but it has narrower spores. Just ideas, no hard evidence.


Surely there are many things on Juncus... unreported.
