Schröt., Pilze 1(1): 149 (1884) Uromyces dianthi is a fungus species and plant pathogen infecting carnations and Euphorbia.

It was originally published as Uredo dianthi by mycologist Christiaan Hendrik Persoon in 1801, before it was transferred to the Uromyces genus in 1872 by Gustav Niessl von Mayendorf.

[2] It is known as Carnation rust, it appears as an irregular shaped yellowing of the leaf and stem.

It can be spread by wind currents (infecting leaves through the stomata in damp conditions) and it can also overwinter in the soil.
