(2/2) Grey leaf spots can be observed in the middle of some rust pustules, likely caused by an #hyperparasite fungus. Why not #Ramularia coleosporii?

Leaf spots on wild arum (#Arum maculata), maybe caused by #Ramularia ari (Millau, FR). Unfortunately I was unable to get any spores from them.

#Rust of broadleaf dock (#Rumex obtusifolius), caused by #Uromyces rumicis, here with a mix of urediniospores & teleutospores (Les Clayes-sous-Bois, FR). Reddish spots are caused by #Ramularia rubella. Apparently bad biocontrol agents based on the prosperity of this plant...
