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

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.
Check Ellis & Ellis, or Grove: http://www.cybertruffle.org.uk/cyberliber/01209/0354.htm
