Hi!

I tentatively determined this observation as Nectria peziza. Traits fit well to my understanding. Does exist something similar I am not aware off? Your help is appreciated very much.

Re : Nectria peziza?

Hi,
your fungus is clearly a member of Hydropisphaera peziza complex, there are several species belonging to this group. I'm working on this complex . It would be interesting to examine your collection if you could send it to me at:
Ascofrance,
64 route de Chizé
F-79360 Villiers en Bois
France

Thank you very much in advance

Christian

Re : Nectria peziza?

Hi Christian,

Unfortunately I've already sent the sample to Mycotheca and lichen herbarium (LJU-Li) of Slovenian Forestry Institute in Ljubljana, Index Herbariorum LJF. I will contact people there and ask for a piece of it. When I get it back I will send it to you. May be they will be also prepared to send it directly to you. Anyway, I will do my best to help you.  I am very curious  :-)

Regards

Amadej

Hi Christian,

I just sent a sample of my collection obtained from Slovenian Forestry Institute by registered mail to your address above. You should receive it in few days.  News about the results of your examination would be very appreciated.

Warmest regards
