Hosts : Gahnia sp. On peduncles. Type: Herb. Berk., Kew, No. 4748. Auckland, Sinclair !
Gahnia pauciflora T. Kirk. On peduncles. Herb. No. 2190. Silverstream, Upper Hutt, Wellington, H. Hamilton ! Jan., 1924.

In a former paper on the Ustilaginaceae of New Zealand (Trans. N.Z. Inst., vol. 55, p. 414, 1924) the name Elateromyces Bubak was used for a genus characterized by the presence of "elaters" in the sori. I find that the name Farysia was used by Raciborski for a species (F. javanica Racib.) possessing this same character, and, as Raciborski's name has priority, the three species included in Elateromyces should be cited as under FARYSIA Raciborski, Bull. Acad. Sci. Cracovic, p. 354, 1906.

F. endotricha (Berk.) Sydow, l.c.
Syn. Elateromyces endotrichus (Berk.) G. H. Cunn.

When in England recently I examined the type of this last species (Herb. Kew., No. 4748), and find that the description given in my former paper is inaccurate, the spores especially being wrongly described. The following amended description has been drawn up from the type specimen :

Farysia endotricha (Berkeley) Sydow, l.c. (Fig. 2.) Cyperaceae. Sori on peduncles and main axes of the inflorescences, not in ovaries, jet-black, compact, elliptical, up to 20 mm. long; 8 mm. wide ; elaters short, up to 5 mm. long,. stout, black, curled, giving to the sorus a decidedly velvety appearance. Spores globose or shortly elliptical, 12-18 mmm. diam. ; epispore dark olivaceous or dark chestnut-brown, 1 mmm. thick, covered with numerous ;flattened irregular tubercules, the crevices between giving a distinct areolate appearance to the spores.

The latter host is endemic, and not uncommon throughout both Islands (Cheeseman, Fl. N.Z., p. 793, 190). With this emended description it will be seen that the areolate nature of the epispore markings separates this from the other two species recorded from New Zealand. The figure given by Berkeley is inaccurate in that the elaters are much exaggerated, and the spores do not arise from them as his figure represents.
In the Farysia (Ustilago) endotricha folder at Kew (labelled "U. tr-icho-pho-ra Kunze") are numerous collections. In working over these I found that only the type collection, consisting of one specimen from which Berkeley prepared his illustration, is of this species, all others being Farysia olivacea (DC.) Syd. This applies also to the "co-type" specimen of Cooke, which was acquired when his herbarium was bought by the Kew authorities.

F. olivacea (DC.) Sydow, Ann. Myc., vol. 17 p. 42; 1919.
Syn. Elateromyces olivaceus (DC.) Bubak:

Host: Cladium Huttoni T. Kirk. In ovaries. Herb. No. 1640. Sea-shore, Tauranga Harbour, Auckland, J. C: Neill ! G. H. C., 20 Jan., 1924. (Type.)
Cyperaceae. Sori in: ovaries, usually destroying all in the inflorescence, concealed within the gldmes, subglobose to elliptical, 1-2 mm. long, black, at first agglutinated in firm masses, becoming apparent only upon rupture of the perigynium, when pulverulent. and granular. Spore-balls of 20-50 or more spores firmly and permanently united by ridged folds, irregularly elliptical, subg1obose or angular; 48-110 X 40-70 mmm., black, : opaque. Spores irregular in size and shape, obovate, cuneate, or angular,15-25 X 14-20 mmm. ; epispore dark brown, smooth on the united faces, covered with coarse deciduous tubercules on.the:free 1-2 mmm :thick where smooth, up to 8 mmm. thick on free surface, often with lateral winged projections at margins of free surfaces.
The host is endemic and confined to the North Island, where it is apparently common on the margin of certain lakes (Cheeseman, Fl. N.Z., p.:787, 1906).
I have been unable to germinate the spores The spore-balls of this species are so firm that separation of the spores is not: possible unless the balls are first boiled in lactic-acid solution, or treated for some time with caustic-soda solution. The spores appear as if covered on their free Surfaces with large, irregular, deciduous tubercules, the crevices- between giving. to the spores a decidedly areolate appearanceThe spores are not unlike those of T. lepidosperma McAlp., in that they are thickened and much roughened on their free surfaces, but the spore-balls are quite distinct, being much larger in size, more irregularly angular in shape,. and spores are much larger.
