No host plant alternation, no aecia. The cinnamon brown uredinia that are formed first cause swellings, up to several centimeters long, on the petioles; the later formed ones are minute, brown; spores apically with a thickened wall; 3 equatorial germination pores, each one capped by a low papilla. Telia small, pulverulent, dark brown, partly derived from the uredinia; spores two-celled, verucose; pedicel deciduous.
