thyriothecia on leaves of Betula nana from Norway
Lothar Krieglsteiner, 28-07-2018 16:47
Lothar Krieglsteiner

... collected at 7.7.2018 in the National Park of Lierne (Norway -near the Swedish Border), on leaves of Betula nana in "fjell" vegetation, about 1100 m NN, together with Venturia ditricha.


Unfortunately, the spores could only be observed inside the ascus.


I looked up in Ellis & Ellis but could not find a good match.


Can somebody provide me with a proposal?


Best regards, Lothar

Are you sure this is not a Coccomyces? Possibly dentatus but it's difficult to tell from the macro images.

Hello Paul,


thank you very much. Yes, you are right - I fully "stood on the tube" as I would say in German slang.


Best regards, Lothar
