Symptoms

Leaf rust and partial defoliation

 

The fungus:

 

Uredinia amphigenous, forming pale discolourations, scattered, minute, pulverulent, erumpent, cinnamon coloured; Uredospores globose to subglobose, widely echinulate, golden brown, 18–24 µm diam., outer wall thick (3–4 µm), 6–8-germ pores. Telia similar to uredinia sori, darker; teliospores globose to subglobose, apex small papilla, verrucose, brown, 16–22 × 15–20, pedicel short, hyaline, fragile, brownish (Sydow & Sydow 1910).

 

Notes:

 The rust symptoms of Uromyces lupincola Bubák are similar to Uromyces renovatus; the two species can be distinguished easily by morphology.  U. lupinicola has thinner walled urediniospores and minutely warty, larger, ovoid to pyriform teliospores.

 

Uromyces renovatus is morphologically similar to Uromyces anthyllidis (Grev.) J. Schröt., but infects different hosts.
