Description: II. Uredosori crowded in epiphyllous, orbicular groups up to 5 mm. diam., deeply sunken in
the tissues so that the apertures alone are visible, 0.5 mm. diam. Spores shortly- elliptical,
slightly obovate, often angular, 40-56 x 32-44 mmm. ; epispore pallid cinnamon-brown, 4-5
mmm. thick,, sparsely and irregularly echinulate; germ pores equatorial, 4, obscure.
Notes: The host is endemic and occurs in both Islands; but is confined to the Tararua Range in the
North Island. (Cheesem. 1925, p. 1024). The sori resemble aecidia in that they are submerged
within the flask-shaped cavities in the host tissues; the resemblance is further strengthened in
that the cavities are in part lined with fungous tissue in the nature of a pseudoparenchyma; but
as the spores are not in chains, and as no definite peridial cells are present, the plant must be
considered an Uredo.
The species is named from material taken from a collection of the host in the Petrie
herbarium, collected by the late Mr. T. F. Cheeseman.

Description: Type: Rust and Smut Fungi; Description: Uredinia crowded in roughly circular groups, deeply submerged in flask-shaped cavities in the host tissue with only the apertures showing; on the upper surfaces of leaves. Urediniospores elliptical, often angular, 40–56 × 32–44 μm, sparsely echinulate, pallid cinnamon brown.
