Broad-leaved Dock (Rumex obtusifolius) close-up of leaf showing the red blemishes caused by Ramularia rubella, a plant pathogen in Ascomycota that infects Rumex species. Infection produces reddish spots on leaves. The red color is caused by the production of rubellin, a photodynamic anthraquinone-derived phytotoxin.
