Hello,I found these black small frb on leaves of phragmites, just covered under the upper layer. Size 0,15mm. Spores 3/4 septate and 26/29x6/6,5µm.
Any suggestions?
regards,
Ralph

Hi Ralph,
Yes it's a Stagonospora species. But giving a species name is more difficult.

Hi Ralph,
below the pages of Sutton 1980 on Stagonospora. Maybe it helps.

Re : Unknown species on phragmites leaves
Thx Martin. As spores are < 30 µm long I have 2 choices but none of these 2 apear on phragmites.

Re : Unknown species on phragmites leaves
Hello Ralph,
It's close to Stagonospora subseriata (most common on Molinia) even if the spores you described are a bit small. I still think it's that one.
