Rust fungus

A fungus of the order Uredinales, parasitic on plants, producing small spore-bodies that appear as fine yellow or orange dots on leaves. Most are specific to a host species or genus and can cause severe losses. Poplars and pines are often devastated by their specific rusts. They have very complex life cycles and may need to overwinter on an alternate host, for example wheat rust on Berberis.
