Morphological Features:
Uredinales includes both autoecious and heteroecious parasites. Autoecious genera infect only one plant host, while heteroecious genera carry out different parts of their life cycle on two different hosts. One example of a heteroecious fungus, Puccinia graminis, the black stem rust of wheat, requires both the barberry bush and a grass to complete its complicated life cycle.
Life cycles of Uredinales are very diverse and complex. Some genera have up to five stages of their life cycle: Spermagonia, Aecia, Uredinia, Telia, and Basidia. Spores are produced in each stage with differing ploidy: spermatia (n), aeciospores (n+n), unidiniospores (n+n), teliospores (n+n to 2n), and basidiospores (n). Genera that do not exhibit all five of these stages either show three or four instead.
Ecology:
Uredinales comprise the most devastating plant pathogens of all Basidiomycota. Genera of Uredinales are responsible for diseases such as: coffee rust, cedar-apple rust, black stem rust of cereals, carnation rust, and peanut rust. There are thousands of other rusts that haven't been listed that are also responsible for being seriously detrimental to many genera of plants.
Despite all of the ecological problems that these fungi cause to plants, recent efforts have attempted to use some of these rusts to control weedy pests.
