I am trying to find an ID for fungus found on Succisa pratensis leaves on plants in the Burren, Eire. The leaves have purple-black spots and larger blotches which may cover as much as half the leaf. I have found records of 3 fungi infecting S pratensis leaves: Erysiphe knautiae Ramularia succisae Synchrytrium succisae but cannot find phots to aid wih ID. Can anyone help? Many thanks
