Teliospores elliptical, 1-septate, 30–40 × 16–22 μm, finely pseudo-reticulate, golden brown; pedicel deciduous.

Notes: This rust was first recorded by Wakefield (1917) on Hoheria. Cunningham (1923b) using the same specific epithet described it as a species morphologically distinct from Puccinia plagianthi. Later (1931a) he concluded that it was synonymous with P. plagianthi. Rust on Plagianthus and Hoheria is common in areas from Taranaki southwards in the North Island and in the South Island. It is an indigenous species occurring also in Tasmania. All host plants are endemic to New Zealand.

Notes: Near to P. Plagianthi McAlp., but distinguished by the smaller spores, with granular (not reticulate) epispore. From P. Abutili it differs in the narrower spores with more finely granular epispore.
