Descriptions
Host: Olearia macrodonta Baker. On leaves and petioles. Herb. No. 277. The track; Clinton Valley (Otago), E. H. Atkinson ! 18 Jan., 1920. (Type.)
0. Spermogones amphigenous, chiefly epiphyllous, sparse, associated with the aecidia.
I. Aecidia hypophyllous and petiolicolous, crowded in irregularly-shaped groups up to l0 mm. long, seated on discoloured distorted spots visible on the upper surface, pallid yellow. Peridia immersed, the margins alone showing, 0-1-0-2 min. diam., margins incurved, dentate, white. Spores polygonal, elliptical, or obovate, 25-37 X 18-24 mmm.; epispore hyaline, densely and rather coarsely verruculose, 1 mmm. thick, cell-contents tinted yellow, granular.

0. Spermagoniis amphigeniis, praecipue epiphyllis, sparsis, aecidiis immixtis. I. Aecidiis hypophyllis et petiolicolis, in catervis inaequalibus ad 10 mm. longis, in maculis discoloratis distortionibus, luteis. Peridiis immersis, 0.1-0.2 mm. latis, marginibus incurvatis, dentatis, albis. Aecidiosporis polygoniis ellipticis vel obovatis, 25-37 X 18-24 mmm.; episporio hyalino, solide rustice verruculoso, 1 mmm. crasso, contentu luteo, granuloso.
The host is endemic, and is abundant throughout. (Cheeseman, 1906, p. 286.)
This species is separated from Aecidium Oleariae McAlp. on account of the much larger spores. Moreover, the minute immersed peridia and distorting habit are distinctive features.

Puccinia atkinsonii G. Cunn. 1923
This endemic rust species is common throughout New Zealand on Olearia spp. It may cause considerable distortion to shoots and leaves. As host plants are only under shrubs in the indigenous forest, the rust is of no economic importance. Cunningham (1924a) described the aecidial stage on Olearia macrodonta as Aecidium macrodontae: he (1924b) described this rust on Olearia rani (syn. O. cunninghamii) as Puccinia heketare. He liter (1931a) listed these species as synonyms of P. atkinsonii.
Puccinia atkinsonii G. Cunn. 1923
Type: Rust and Smut Fungi; Description: Aecia in crowded groups, bright orange, on distorted spots up to 3 cm long; on leaves, petioles, and shoots. Aeciospores subglobose, elliptical or tear-shaped, 25–33 × 20–28 m, densely verrucose, hyaline. Telia crowded, minute, circular, dark chocolate brown, powdery, up to 1 mm in diameter; buried in dense tomentum on the lower surfaces of leaves. Teliospores broadly elliptical, 1-septate, 40–65 × 20–35 μm, pallid chestnut brown; pedicel deciduous.
Distribution: Northland, Auckland, Coromandel, Bay of Plenty, Taranaki, Taupo, Wellington, Hawkes Bay, Nelson, Westland, Fiordland, Marlborough Sounds, Marlborough, Dunedin.; 1st Record: Cunningham (1923a).
Significance: None.; Host(s): Olearia arborescens × lacunosa, O. ilicifolia, O. ilicifolia × lacunosa, O. macrodonta, O. rani.
