BioInfoBioInfo (www.bioinfo.org.uk) has 43 host/parasite/foodplant and/or other relationships for [Puccinia magnusiana/Uromyces dactylidis] (buttercup rusts)

The closely similar aecial stages of these two rusts are both very common on Creeping Buttercup (Ranunulus repens) and Bulbous Buttercup (Ranunculus bulbosus). The later stages are found on different hosts: Common Reed (Phragmites australe) for the Puccinia, while the Uromyces grows on a variety of other grasses: Cocksfoot (Dactylis glomerata), Fescues (Festuca) and Meadow Grasses (Poa).

The aecial stages can only be distinguished by the thickness of the outer cell walls of the peridial cells (the inner walls have the "crushed ice" ornament):

Species Outer walls Inner walls
P. magnusiana: 7-8µm
U. dactylidis: 8-14µm 3-5µm
