Puccinia gilgiana
is one of five Australian species of rust fungi on hosts in the Goodeniaceae (McTaggart et al. 2014).  Puccinia gilgiana differs from the other species, P. brunoniae, P. dampierae, P. saccardoi and Uromyces scaevolae, as it has urediniospores and occurs on Lechenaultia. A systematic analysis recovered P. gilgiana in a monophyletic group sister to P. lagenophorae (McTaggart et al. 2014).
