# Uredo

Uredo is a genus of rust fungi: long considered incertae sedis in the order Pucciniales, but now placed in the family Pucciniaceae. 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".

## Taxonomy

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. 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; it has been used as a biological control agent against invasive rubber-vine, Cryptostegia grandiflora.
