Pathogenicity

This endemic rust occurs throughout the South Island and in the Wellington Province in the North Island of New Zealand. All host species [Poa spp.] are indigenous. Three are endemic, whilst Poa caespitosa occurs also in Tasmania and Australia.

Collections Examined

Notes

This rust is endemic to New Zealand, occurring on both native and introduced species of Poa. Microscopically, the uredinia of U. otakou differ from those of Puccinia brachypodii var. poae-nemoralis, the other common rust on Poa spp., by the absence of paraphyses. The germ pores on urediniospores of U. otakou are more obvious than those of P. brachypodii var. poae-nemoralis, and they have a slight, but noticeable, cap.
