Iris Rust is a microscopic fungus. Observations without microscopic or molecular confirmation are speculative.
Iris Rust (Puccinia iridis) is parasitic on several species of irises (Iris spp.) in North America. It is most often found in its uredinial stage (asexual) and causes orange-brown pustules on the leaves of irises.
This species can be found in gardens with cultivated irises.
