Goodmorning, 

This week I received an email from a friend with some photos of a Pleospora or Phaeosphaeria species on reed.
She thinks it could be Pleospora abscondita.
She says: " White dots, black flat and round underneath the surface, spores 35-40 mu long".

Spores: 5-septate, with longitudinal septa

The information I found and  received from Riet van Oosten suggests that it could also be Phaeosphaeria vagans. The other possibilities are Phaeosphaeria Phragmitis (not recorded in the Netherlands yet) and Phaeosphaeria Phragmicola. 

Which of these species could it be?

Yours sincerely, 

Anna

Re : On Reed
May I refer you to a similar issue with these species as detailed by Riet van oosten at this forum on 18-05-2018 at:

Appears more likely to be P. abscondita?
