Leaves spots on Sorbus
Marcel Heyligen, 21-09-2020 20:34
Marcel HeyligenHello anybody

I need help with the determination of leaves spots on Sorbus aucuparia. 
Only found conidia spores, 15.9-20.3 x 6.6-8.4 µm.
Also look for literature of fungi on Sorbus

Thanks in advance
Marcel

The acervuli and conidia remind me of Diplocarpon rosae, which is normally found on Rosa. Since Sorbus is in Rosaceae it could possibly be a host.
