I see. It was not meant in a bad sort of way just information.

well, it is quite unusual if one is completely unfamiliar with Puccina!

I may have married a Rust, but I don’t know much about the rust fungi.
There is always something new to learn.

It’s not unusual, the scent thing.

There are many Puccinia species that have developed that feature.
See my observations of Puccinia punctiformis, this is also one of the honey dew rusts. And somewhen I will post Puccinia sii-falcariae, another one.

The rust changes both host form and produces scent? That’s wild.
