Reported1 Hosts of Puccinia hemerocallidis
While Dianella tasmanica has been confirmed as a host of Puccinia hemerocallidis in Florida, attempts to infect daylily with rust from Dianella and vice versa have not been successful according to reference 9 below. Dianella tasmanica is a member of the daylily family, Hemerocallidaceae.
The hosta species below have also been listed as hosts of the uredial/telial stage of daylily rust, but rust on hostas in Japan has since been demonstrated as Puccinia funkiae, and is not the same as daylily rust, Puccinia hemerocallidis. Please see the note below.
It should be noted that, at least in the case of hosts listed in the Rust Flora of Japan, the information is compiled from published papers and not necessarily confirmed by specimen-based studies or inoculation experiments. This list includes species reports only and does not include cultivated Hemerocallis cultivars, which vary in their susceptibility.
Dr. Y. Ono in Japan has confirmed experimentally that the rust observed on Hosta in Japan is a different species of rust fungus, Puccinia funkiae, although both hosta rust and daylily rust share Patrinia villosa as alternate host 6,7.
