Rusty brown rust on leaf of 'water avens'
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
I think your plant is Meadowsweet and the rust therefore is Triphragmium ulmariae.
Brilliant, thanks for that, Robert, Have to say I didn't think that it looked like water avens but was going on information received.
We'll add this species to the Bio-blitz list.
