Uredinia amphigenous, mainly on lower (abaxial) surface, cinnamon-brown, pulverulent, up to 1 mm long or confluent and linear, surrounded by the ruptured epidermis. Urediniospores (28-) 33-39 (-46) x (24-) 26-31 (-35) µm, globose or broadly ellipsoidal, wall (1.5-) 2-3.5 (-4) µm thick, golden-brown, echinulate, germ pores 3-4, equatorial.
Urediniis plerumque hypophyllis (abaxialibus), cinnamomeo-brunneis, pulverulentibus, usque ad 1 mm longis. Urediniosporae (28-) 33-39 (-46) x (24-) 26-31 (-35) µm, globosae vel late ellipsoideae, membrana (1.5-) 2-3.5 (-4) µm crassa, aureo-brunnea, echinulata, poris germinationis 3-4, aequatorialibus. In foliis cyperaceae speciei Carex chathamica Petrie et C. trifida Cav.
There are four species of rust fungi recorded on Carex in New Zealand. Urediniospores of Uredo chathamica differ from those of the four Puccinia spp. in size and number of germ pores. Carex chathamica is endemic to the Chatham Islands, while C. trifida, which is indigenous to the South Island and the subantarctic islands of New Zealand, also occurs in Chile and the Falkland Islands.
Holotypus PDD 44228.
