Uredo is a genus of rust fungi: long considered incertae sedis in the order Pucciniales, but now placed in the family Pucciniaceae. [2] This long-established genus, together with the closely-related Uromyces (which some authorities consider to be synonymous), give their names to "uredo-type" fungal spore structures such as "urediniospore" and uredinium".
The classification of fungal taxa based on only morphological characteristics has long been recognised as problematical, so the Pucciniales have been reviewed over long-term studies using three DNA loci. [2] In the 2021 and other studies, a substantial number of species have been placed in other genera including Puccinia , Hemileia , Ravenelia and Uromyces: including the original type species: Uredo betae Pers., 1801. On the other hand, species have also been transferred here from other genera, sometimes in different families. For example, Uredo cryptostegiae (better known as Maravalia cryptostegiae and also Scopella cryptostegiae), was provisionally placed here; [2] [3] it has been used as a biological control agent against invasive rubber-vine, Cryptostegia grandiflora .
As of 2023, Species Fungorum includes the following as valid (out of approximately 1600 species names): [4]
Note:
Trabutia is a genus of fungi in the family Phyllachoraceae.
Pucciniastrum is a genus of Basidiomycota fungi. Pucciniastrum species, like all rust fungi, are obligate plant parasites.
Phaeodothis is a genus of fungi in the family Didymosphaeriaceae.
Asterinella is a genus of fungi in the Microthyriaceae family. It is commonly found on decaying leaves or dead plants.
Maravalia is a genus of rust fungi in the Chaconiaceae family. The widespread genus contains about 35 species that grow on angiosperms.
Chrysomyxa is a genus of rust fungi in the family Coleosporiaceae. The genus, widespread in the Northern Hemisphere, contains about 23 species. Rust fungi in the genus Chrysomyxa occur in boreal forests of the northern hemisphere on Pinaceae,, and most species alternate to angiosperm hosts in the Ericaceae.
Passalora is a genus of fungi in the family Mycosphaerellaceae. It has about 250 species.
Pucciniosira is a genus of rust fungi belonging to the family Pucciniosiraceae.
Hemileia is a genus of rust fungi, now placed in the family Zaghouaniaceae, but long considered incertae sedis in the order Pucciniales. This genus has a pan-tropical distribution and includes important crop plant pathogens, such as the causative organism of coffee leaf rust.
The Sphaerophragmiaceae are a family of rust fungus genera in the order Pucciniales, based on the type genus Sphaerophragmium and placed in the suborder Uredinineae.
