- Observation Rust symptoms were observed on Myrtus communis in several Lisbon gardens.
- Observation Disease prevalence was 50% across the surveyed gardens, with no symptoms in five other gardens.
- Observation Affected plants had 100% of new shoots affected.
- Observation No symptoms were observed on other Myrtaceae.
- Observation Urediniospores of the fungus measured 18.2–21.7–26.7 × 12.1–16.6–21.7 μm.
- Observation ITS and LSU sequences identified the fungus as A. psidii.
- Intervention effect Inoculated M. communis developed leaf tumefactions after eight days, whereas control plants stayed asymptomatic.
- Observation Uredinia erupted 10 days after inoculation of M. communis.
- Observation Uredinia from inoculated plants had characteristics identical to those of isolate ApTA02.
- Observation This is the first report of A. psidii on outdoor Myrtaceae in Europe.
