Trichopezizella rubroguttata (?) sur Polygonatum multiflorum
Bernard CLESSE, 03-02-2018 21:28
Bernard CLESSEBonsoir tout le monde,

Trouvé récemment ce que je pense être Trichopezizella rubroguttata sur sceau de Salomon multiflore. Les asques ont systématiquement un crochet à la base.

Qu'en pensez-vous ?

It is a good question, but the asci look a bit strange, their contents are guttulate unlike these Trichopezizellas. The asci are amyloid?
You don't find living asci and free spores?

Good evening Zotto,

The asci are IKI- and I have not found any spores, but lots of small conidia.

I'll double check if I see spores in other apothecia

In fact, these thousands of small spores (or conidia?) of different sizes and shapes that I see under the microscope come from inside asci, I do not understand much about it.

Hi Zotto,

Would you have a conclusion for this Trichopezizella with these asci and these strange spores ?

Re : Trichopezizella rubroguttata (?) sur Polygonatum multiflorum
Yes, now I have. It was my suspicion, but I wasn't sure at all. You have two organisms in one: T. nidulus with the hymenialparasite Helicogonium- I guess a new species.

Would be good to photograph more of the normal spores, they are actually the ascuspores. Especially the stage when they produce a terminal conidium is important since some species form conidia on the broader and and some on the narrower, but this is a bit variable.

In any case spore and conidial size should be measured.

You can consult my paper on the genus in Nova Hedwigia 69: 1-71.

I send it by mail.

Re : Trichopezizella rubroguttata (?) sur Polygonatum multiflorum
Interesting! I learn every day (I did not know there were parasitic fungi inside asci). I will wait for your mail to see more clearly.

Thank you very much, Zotto!

Re : Trichopezizella rubroguttata (?) sur Polygonatum multiflorum
Not inside asci, the complete asci belong to the parasite. Therefore they are inamyloid (in all Helicogonium), and have croziers.

Re : Trichopezizella rubroguttata (?) sur Polygonatum multiflorum
Ah OK, Zotto, I understand better and so I photographed helicogonium asques ...
Thank you for your additional explanations
