0. Spermogones hypophyllous, immersed, sparse, scattered, associated with the aecidia.
I. Aecidia hypophyllous, in scattered groups up to 5 mm. diam., irregular, seated on discoloured spots which are absent in certain specimens, pallid-orange. Peridia depressed - globose, or angular, flattened, 0.2 mm. diam., immersed and covered by the epidermis, opening by an irregular apical pore, hyaline. Spores subglobose, polygonal or elliptical, 22-30 x. 18-22 mmm; epispore hyaline, densely and minutely verruculose, .1-5 mmm thick, cell-contents vacuolate, orange.
II. Uredosori amphigenous, chiefly hypophyllous, scattered, orbicular or elliptical, 0.5-1 mm. diam., bullate, pulverulent, cinnamon -brown, surrounded by the ruptured epidermis. Spores subglobose or elliptical, 20-30 X 18-23 mmm.; epispore pallid cinnamon, moderately and finely echinulate, 1-1.5 mmm. thick, cell-contents vacuolate, cinnamon; germ-pores 2, equatorial, conspicuous.
III. Teleutosori amphigenous, in small scattered groups of 3 or 4 sori, seated on dead and discoloured spots, bullate, pulverulent, dark chestnut-brown; partially covered by the ruptured epidermis. Spores elliptical, seldom subclavate, 28-38 X 15-20 mmm.; apex. rounded, not thickened; base slightly attenuate, or rounded, both cells about the same size; constricted at the septum; epispore smooth; chestnut-brown, 1.5 mmm. thick; pedicel persistent, hyaline, up to 50 X 8 mmm.; germ-pore of the upper cell apical, obscure, basal pore immediately beneath the septum; obscure.

Distribution: Chile

III. Soris teleutosporiferis amphigeniis, in raris catervis 3-4 soriis, in maculis decoloratis, bullatis, pulverulentibus, fusco-castaneis, rupta epidermide cinctis et partim tectis. Teleutosporis ellipticis vel subclavatis, 23-38 X 15-20 mmm.; apice rotundato, non incrassato, basi leniter attenuato vel rotundato; ad septum constrictis; episporio leve, castaneo, 1.5 mmm.. crasso; pedicello persistente, hyalino, ad 50 X 8 mmm; foramine germinis cellulae superioris apicale, obscuro, foramine basali etatim infra septum, obscuro.

The host is endemic, and is not uncommon in the North Island, but is sparingly distributed in the South. (Cheeseman, 1906, p. 553.)

The rust occurs in Chile and New Zealand: the host plant [Euphrasia cuneata] is endemic to New Zealand. Cunningham (1931a) stated that it is not uncommon in mountain regions in the North Island but is sparingly distributed in the south.
