Ethan CrensonHello all, This was found last weekend on a hardw

... also in National Park Eifel, Germany, 16.11.2019.
There is no KOH-reaction, so this can not be an Nectria(ceae).
The spores are 1-septate, and about (8)-9-11,5/2,5-3,5 µm, with oil 3.
The perithecia look rough under the lens (maybe like Nectria cinnabarina), but not notably hairy.
Can somebody provide me with a hint?
Best, Lothar


Hello Christian,
thank you very much for your repeat!
I think there was a lot of oil in the structures you mention.
I did not test lactic acid - I will try to do this soon.
Best regards, Lothar

Hello Christian - and other readers,
in the meantime I received lactic acid (I did not have and it was not so easy to get!) and now I prepared one ascoma in this medium. The red colour is changing into (orange) yellow.
Does this mean it is Clonostachys? And can there be a proposal for a species? Is there a key for the species of this genus?
Thanks and best regards, Lothar


thank you very much, Christian!
I will try to find an anamorph on the twig - if I am successful I will write again.
Best regards, Lothar
