small ascomycete on Alnus leaf
Lothar Krieglsteiner, 17-04-2020 17:26
Lothar Krieglsteiner... two days ago, on a skeletized leaf of Alnus glutinosa near Hintersteinenberg (Germany, Baden-Württemberg). The ascomata are very small and black, a bit flattened and immersed in the epidermis of the leaf - there is no ostiolum.
I think it should be a Diaporthales, I do not find a fitting species.
The spores are about 11-15/2-3 µm, the asci about 50-60/8-10, with a strongly developed (very good visible in phloxine, but inamyloid) apical apparatus.
Who can provide me with a hint?
Best, Lothar

Hi Lothar,
