The genus is the second-largest plant pathogenic rust genus, which is responsible for various plant affecting diseases, and it has major effects on both agricultural and non-agricultural plants. The genus is generally characterized by its unicellular teliospores (thick-walled resting spores) that help to characterize it and distinguish it from another important and large rust genus, Puccinia.[3]
The Uromyces fungal species have been recorded on various host plants belonging to a wide range of the families, including Asteraceae, Euphorbiaceae, Fabaceae, Liliaceae, Loranthaceae, and Poaceae. Family Loranthaceae is listed to be the most affected by the fungus.[3]
As of 2023 August 22[update], the GBIF lists up to 1,048 species,[2] while Species Fungorum lists about 1,239 species (with many former species).[4] The Encyclopedia of Life lists 969 species.[5]
