Seventh Supplement to the Uredinales and Ustilaginales of New Zealand. By G. H. Cunningham, Mycologist, Plant Research Station, Palmerston North, [Issued separately, 23rd August, 1930.] During the preparation of the manuscript of a book on the Rust Fungi of New Zealand, a critical revision was made of all material in my herbarium. This has led to the erection of several additional species; and to the alteration of the specific names of a few. During the course of the work additional material has come to hand, containing several undescribed species. These, together with emendations and notes, form the subject of this paper. Uredinales. 1. Hamaspora australis n. sp. Fig. 1. O. Pycnia unknown. III. Teleutosori hypophyllous, scattered or crowded in irregular groups, seated on indefinite pallid spots which are visible on the upper surface, elliptical, 0.5-1 mm. diameter, pulverulent, surrounded by the ruptured epidermis. Spores aggregated into pallid yellow fibrils up to 20 mm. or more in length, fading with age, 4-6 celled, long-cylindrical, 100-180 × 14-22 microns; apex strongly acuminate, tapering to a fine sharp point, thickened up to 10 microns, base truncate; not constricted at the septa; epispore hyaline, smooth, 1 micron thick; pedicel persistent, continuous with the spore, tapering basally to a fine point, up to 600 microns long, 10-15 microns thick immediately beneath the spore, hollow; germ pore solitary in each cell, seen only at germination. Hosts: Rubus australis Forst. f. Auckland: Taupo, 400 m. Wellington: Palmerston North, 100 m.; Feilding, 50 m.; Ruahine Range, 1200-1500 m. Nelson: Glenhope, 500 m. Canterbury: Otira Gorge, 500 m., type collection; E. H. Atkinson. Peel Forest, 300 m. Otago: Makarora, 280 m. Herekopere Islands. Rubus schmidelioides A. Cunn. Hawkes Bay: Lake Tutira, 250 m. Rubus schmidelioides var. coloratus Kirk. Westland: Mangles Gorge, 500 m.; Maruia Springs, 700 m. Rubus schmidelioides × australis. Wellington: Feilding, 50 m. Canterbury: Hope River, 700 m.; Boyle River, 750 m. Westland: Maruia Springs, 700 m. Distribution: Endemic. All hosts are endemic and not uncommon throughout (Cheesem. 1925, p. 500). In a previous paper (1924, p. 22) I considered this species under Hamaspora acutissima. Since this publication many more collections
