Descriptions
Aecidium macrodontae G. Cunn. 1924
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.
