Elisabeth StöckliBonsoir,Sur feuilles d'Osmunda regalis (Saulaie),
Hallo,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.
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
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

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
Je l'avais oublié celui-là !
Thank you for examining this species. I never heard of it... is it rare?
regards
Christian
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 ;)

I am always astonished by the wonderful sections you are able to produce - how do you do it?
amitiés
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
