Description: 0. Unknown.
III. Teleutosori scattered, hypophyllous, orbicular, 0.5-1 min. -diam., pulverulent, orange or
pallid chestnut-brown, naked but covered by the tomentum of the leaf. Spores linear-oblong,
or sub-clavate, 80-144 x 20-30 mmm.; apex rounded or less frequently slightly subacuminate,
not thickened, base subattenuate, lower cell longer and narrower than the upper, usually
cuneiform; constricted :at the septum; epispore 1 mmm. thick, tinted, almost hyaline, smooth;
contents orange yellow; pedicel persistent, hyaline, length of the spore; germ pore of the
upper cell apical, basal pore immediately beneath the septum, both obscure.
Notes: The host is endemic and occurs in both Islands (Cheesem. 1925, p. 924).
The rust is very close to P. hectoreasis G. H. Cunn. on Senecia Bidwillii, but differs in the
thinner, tinted epispore, and slightly different shape of the teleutospore. The absence of an
aecidium may also be a diagnostic character, but in the absence of pycnia it cannot be stated
definitely that an aecidium does not occur in the cycle of the species under consideration.
The teleutospores germinate immediately on reaching maturity,, giving to the sori a distinct
orange colour.

Description: Type: Rust and Smut Fungi; Description: Only the telial stage is known. Telia scattered, rounded, orange to pallid chestnut brown, 0.5–1 mm in diameter; on the lower surfaces of leaves, hidden in the tomentum. Teliospores oblong to subclavate, 1-septate, 80–144 × 20–34 μm, smooth, pale brown to almost hyaline; pedicel persistent.
Distribution: Distribution: Taupo, Mackenzie.; 1st Record: Cunningham (1928).

Notes: The host plant [Olearia nummularifolia] is endemic, occuring in mountainous regions in both
the North and the South Island. The rust has been found in both islands.
