	Actually rusts are a type of fungus, order Uredinales, which 
are typically host-specific parasites. Sometimes there are two hosts 
depending on the stage of the life cycle, perhaps the most well known 
being cedar/apple rust. Definitely fungus though. As to the specifics 
of the Arisaema rust, including any treatments, we'll have to go to 
someone who's worked with this species or group.
