Descriptions
Habitat: Parasitic upon the spores of the following species : Uromyces otakou G. H. Cunn. (II); U. Polygoni Fck. (II); Uromycladium alpinum McAlp. (II); Urom. notabile McAlp. (II); Urom. Tepperianum (Sacc.) McAlp. (III); Puccinia Caricis Schroet. (II, III); P. Chrysanthemi Roze. (II); P. Coprosmae Cke. (III); P. Elymi Westnd. (II); P. Hoheriae Wakef. (III); P. Hydrocotyles Cke. (II); P. juncophila Cke. et Mass. (II); P. Morrisoni TVIcAlp. (II); P. Plagianthi McAlp. (III); P. Poarum Niels. (II); P. pulverulenta Grev. (II); P. punctata Link. (II); P. whakatipu G. H. Cunn. (II); P. Unciniarum Diet. et Neg. (II, III); Phragmidium novae-zelandiae G. H. Cunn. (I); Phr. Potentillae P. Karst. (I, II);
Pycnidia superficial or immersed, scattered or gregarious, conico-globose, elliptical, obovate, or depressed-globose, 90-120 X 60-100 mmm. diam., ostiolate, smooth; black. Conidia l.-septate, hyaline, fusoid, smooth, 10-18 X 3-6 mmm., slightly or not constricted at the septum, muticate.
Distribution: Europe; North and South America; Ceylon; Japan; Africa; Australia.
From the foregoing it will be seen that in New Zealand this species has been collected on aecidia, caeomata, uredosori, and teleutosori.
The mycelium ramifies through the sori and appears to plasmolyze and disintegrate those spores with which the hyphae come in contact; in certain sore, indeed, it is difficult to obtain any unaffected spores. Generally the pycnidia are superficial and easily seen, but in certain cases, particularly when they are parasitic upon aecidia, they are almost competely immersed, and their presence noted only when sections of the aecidia are examined. Saccardo (Syll. Fung., vol. 3, p. 410, 1884) states that the spores have on either end a few fine bristles; I have failed to observe these, although I have examined numerous microtome sections of pycnidia of all ages. So common are the pycnidia on certain species that they have frequently been mistaken for spermogones, and described as such.
