Unknown species on Fallopia japonica
Ralph Vandiest, 30-01-2014 20:18
Ralph VandiestHallo,

I found this species on  Fallopia japonica but in Ellis & Ellis this substrate isn't mentioned. Fruiting body 0,3/0,4mm, oranje, (curved) spores (7/8septate?)38/50x5µm. Asci 90/100x10/11µm.

Does anybody knows what this is?


Regards,

Ralph

Hi Ralph,


It looks like an Hydropisphaera species.


But with such ascospores, it's very amazing ! Are they striate ?


Have you observed setae on ascomata ?


It's a fungus for Christian.

Re : Unknown species on Fallopia japonica
Hello Alain,


If I look at pictures on the net it is indeed an Hydropisphaera species. I didn't see striate ascospores. When looking at the fruiting body I noticed a kind of net all around it. In the key I have there are only 4 species of mentioned but I just read on the net that there are 18 different species in this gender.

regards

Hi Ralph,
your fungus is very interesting, it would be great if you could send it to me because it is absolutely necessary to cultivate and sequence it.

A lot of thanks,
Christian

Re : Unknown species on Fallopia japonica
Hi Ralph,
Your specimen arrived yesterday.
It is not the genus Hydropisphaera, ascomatal wall doesn't fit with that.
Your fungus is "Nectria" pseudopeziza (Desm.) Rossman.
Thank you, it is a nice collection!
All the best,
Christian

Bonjour Christian,

Thank you for examining this species. I never heard of it... is it rare?

Re : Unknown species on Fallopia japonica
Nectria pseudopeziza is very common species, although it is not a true Nectria.

Hi,

Nectria pseudopeziza is shown on my webpage: https://www.sites.google.com/site/funghiparadise/d---ascomycota-sordariomycetes/hypocreales/nectriaceae/nectria-pseudopeziza-desm-rossman-1979

Very typical with this long, ~7 septated ascospores ;)

Re : Unknown species on Fallopia japonica
Hi Chris,
sections are made at free hand using a razor blade.
It is necessary to make the section on dried material, I know it is difficult but with a lot of training, it's possible.

Good luck with sections,

Regards,
Christian
