No host plant alternation, uredinia and telia. Telia hypophyllous, like the uredinia, brown. Teliospores one-celled, verrucose, on a pedicel of the same length, with a septum close to the spore, upon which the spore breaks off.

notes

this rust is systemic, and hibernates in the underground parts of the plant. Infections therefore may become apparent early in the season
