A microfungus new for East Sussex?

Today, in the cold and the damp most untypical of early September, I found several leaves of bugle (Ajuga reptans) that had been affected by the microfungus Ramularia ajugae. According to the NBN this has been recorded from several places in West Sussex by I can find none for East Sussex.

The fungus makes purplish bordered patches in the leaves that turn into perforations.

I also noted that one of the ragwort leaves was being mined by Liriomyza strigata, a fly I last recorded in Emthree in 2003.
