Farysia endotricha (Berk.) Syd. & P. Syd. 1919

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.
