This is a rare rust of wide distribution. In Europe it occurs exclusively on Meum athamanticum which is not rare. Its morphology is unmistakable.
Provisional assessment: DD.
relatively wide spread in Europe and USA.
There appear to be two sub populations: a North American one on various Apiaceae, and a European one, predominantly on Meum.
There are few records and no recent specimens in the herbaria K, E, B, S and BPI.
Population Trend: Decreasing
Parasitic on Apiaceae generally in North America, mainly on Meum athamanticum in Europe. The host plants are not uncommon.

None
the threats to this species are unknown, and research into dispersal and survival strategies will need to be carried out.
