Cintractia sclerotiformis (Cooke & Massee) G. Cunn. 1924

Hosts : Uncinia caespitosa Boott. In inflorescences. Taheraiti, T. Kirk. (Type in Herb. Kew.) Uncinia leptostachya Raoul. Herb. No. 20. Peel Forest (Canterbury), 120 m., H. H. Allan ! Feb., 1920. Uncinia riparia R. Br. Herb. No. 1257. Peel Forest (Canterbury), 120 in., H. H. Allan ! 5 April, 1919. Mount Peel (Canterbury), 700 m., H. H. Allan ! 6 Mar., 1921. Botanical Gardens, Wellington, 80 m., E. H. Atkinson ! G. H. C. 19 Jan., 1921. J. C. Neill G. H. C. 4 Dec., 1923.
Sori in occasional ovaries, sometimes in all, at first partially concealed within the perigynium, becoming exposed when compact, black, elliptical, up to 6 mm. long. Spores subglobose to elliptical, commonly polygonal, 16-22 X 11-18 mmm.; epispore closely and minutely verruculose, dark brown, 1-5 mmin. thick.
Distribution: New Zealand.
The first two hosts are endemic, the third occurs also in Australia; all are widely distributed throughout New Zealand (Cheeseman, 1906, pp. 801-3).
This is a true Cintractia, for a transverse section shows that it possesses all the characters of this genus. The species is closely related to the preceding, but is separated by the comparatively broader and smaller spores, more conspicuous markings, and thinner nature of the epispore.
I have been unable to germinate the spores.

Smut on seed heads of Uncinia have been recorded only from Wellington and the South Island. The host plants and the smut fungus are endemic to New Zealand.
