Uredo rangelii
''Uredo rangelii'', commonly known as Myrtle Rust, is a fungal plant pathogen native to South America that affects plants in the family Myrtaceae. It is a member of the fungal complex called the guava rust (''Puccinia psidii'')] group. The spores have a distinctive yellow to orange colour, occasionally encircled by a purple ring. They are found on lesions on new growth including shoots, leaves, buds and fruits. Leaves become twisted and may die. Infections in highly susceptible species may result in the death of the host plant.
As of late 2013, it is infecting around 179 species in New South Wales and Queensland, from 41 genera (around 46% of genera in the Myrtaceae) in Australia.〔(Australian Nursery Industry Myrtle Rust Management Plan 2012 ), Nursery & Gardening Industry Australia, accessed November 5, 2013

The rust was first described scientifically in 2006 by mycologists J.A. Simpson, K. Thomas, and Cheryl Grgurinovic.
