I'm glad the info was useful. There are two possibilities with delayed rust, the first as you mention is that a fungicide application has worn off, and the second is that this rust can have a lengthy latent period between infection and actually showing visible rust. If conditions are unsuitable for it, the latent period can extend several weeks.
There's no evidence that daylily rust can infect through root or crown tissue. It typically enters through the stomata in the leaves (and can infect scapes also). Where you'd have to be careful is with the handling, for example if you did have viable spores in the soil mix and touched that and then a leaf you could transfer rust that way. It's not especially likely though.
I recently had to get a new keyboard too, the space bar on my laptop quit working on one side. I'm kind of trying to adapt to typing with my right hand at a different angle so that I can hit the bar in the middle (touch typist) but for anything of length I now have to use a separate keyboard. Frustrating, as I carefully picked this particular laptop because it is so nice to type on.
