"Nectria" on Sarothamnus (Cytisus) scoparius in Germany
Lothar Krieglsteiner, 19-11-2019 17:35

... 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

Hi Lothar,

if there are numerous oily droplets in ascomatal wall and hymenium, you should consider Clonostachys, but did you test ascomata in lactic acid?

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
