Re : yellow Nectria
Bonjour.
A rechercher peut-être dans les Hydropisphaera?.
ëtes-vous certain de la présence de poils ?

Re : yellow Nectria
Hi Ingo, Yannick,
I think it is not Hydropisphaera, the ascomata are too small for this genus and the asci don't fit with it.
Ingo, are you sure that the asci are unitunicate?
It would be necessary to make a  vertical section through ascomatal wall.

Regards,

Christian

Re : yellow Nectria
Hallo Yannick an Christian!

Thanks for answers!


Christian, no I´m not sure with unitunicate asci.


How looks a  vertical section through ascomatal wall?? Have you an picture-example for me? Is it possible to make this on fresh ascomata?


Addition: I have found some picture-examples for vertical section in Zottos dvd, will try it!


Regards
Ingo W

Re : yellow Nectria
Hi Christian!

Thanks for your effort and this wonderful example.
Your drafts are really unbelievable!!
Unfortunatly I´m unable to bring this quality, also this exactly informations.
Even the ascus-walls bring problems to me, I cannot decide, and for vertical section my fungus is to tiny for me.

I guess, Nectria, Tubeufia or other similar generas hang a little to high for me.

Best wishes

Re : yellow Nectria
Hi Yan!

The fungus is unrelated to algae or excrements.
He grows pure on bark, another connection is not visible.
