Descriptions
Hosts: Dauthonia Cunninghamii Hook. f. Base of Stocking Glacier, Mt. Cook, Canterbury, 1,000 m., 1/28. G.H.C. Tasman Moraine, Mt. Cook, Canterbury, 800 m., 1/28. G.H.C. Type. Danthonia flavescens Hook. f. Little Peel, Canterbury, 1,000 m., 1/28. G.H.C.
II. Uredosori hypophyllous, seated on discoloured spots visible on the upper surface, scattered and elliptical when up to 3 nun. long, or aggregated into linear series 1 cm: or more in length, pulverulent, pallid ferruginous brown, partly covered by the ruptured epidermis. Spores subglobose, or shortly elliptical, 36-42 x 32-36 mmm. ; epispore pallid chestnut-brown, 2 mmm. thick, moderately and finely verruculose; germ pores scattered, 7-11, obscure.
Both hosts are endemic and widely distributed (Cheesem. 1925, p. 172)
The spores are larger than those described by McAlpine (1906) for Uromyces Danthoniae from Australia, but otherwise show a general resemblance, especially in the numerous scattered germ pores. The species shows also a general resemblance to Uredo toetoe G. H. Cunn. on Arundo conspicua, but is separated by the much larger spores.
