Rust

As a follow up to my post about Morlais quarries, I have now identified the rust fungus that was so abundant on the leaves of Salad Burnet (Sanguisorba minor). It is Phragmidium sanguisorbae, but as to its status, this NBN dot map gives an idea, but as with all these under recorded organisms I doubt if it gives a particularly accurate idea of its true status. As always with these things, I suppose it is common where the host plant grows.
