Hi to everybodyThese thiny, blackish pseudothecia

... collected by my wife, Katharina Krieglsteiner, near the National Park of Jotunheimen in Norway, Visdalsvegen. road to Spiterstulen, about 1100 m NN, 15.7.2018.
In Ellis & Ellis and other literature I found no matching species - although the genus Gibbera seems to be a good hint (?). Manually I measured the spores to be about 12-13,5/2-3 µm (roughly).
Can somebody provide me with a specific name - or with a hint, at least?
Best regards, Lothar
Did you think at Mycosphaerella genus ?
Alain
Hello Alain,
thank you for this (indeed obvious ...) hint.
So I could look up the species M. minor with fitting details, especially spore form and length (e.g. in Nograsek, Remler: only short notices). M. minor is recorded to be arctic-alpine and polyphagous, but with a preference to Vaccinium an Arctostaphylos (Ericaceae).
Thanks again - and best regards,
Lothar
