(f.) Aecidium dissimenatum Berk., Hdbk. Fl. N.Z., p. 756, 1867. 
Host: Hypericum japonicum Thunb. 
MeAlpine done p. 200) records this rust as occurring in Australia on 
the same host 
(g.) Aecidium monocystis Berk., Fl. N.Z., vol. 2, p. 196, 1855. 
Host: Phyllachne Colensoi Ber erggr. (= Helophyllum strong Hook. f.). 
McAlpine (1906, p. 197) states that this is common on Abrotanella 
forsterioides Hook. f. in the vicinity of Hobart, and doubts de: ddtieniiaGon 
of the host as given above; he claims that it is scarcely likely that the 
ame species would occur on hosts belonging to the Compositae and Can- 
dolleaceae (= Stylidieae). Mr. Rodway, Government Botanist, Hobart, 
s written to me to the same effect; he believes that the species was in 
error stated to have been collected in New Zealand, and was really collected 
in Tasmania. Although Abrotanella occurs in New Zealand, all the species 
are endemic; so that the matter must remain at issue until the original 
ds is correctly determined. 
(h.) Uredo Acaciae дыд Grev., vol. 19, p. 3, 1890. 
Host: Acacia 
The sipon; is too incomplete for determination, but it will doubtless 
prove to be a species of Uromycladium. 
(i.) Uredo antarctica Berk., Fl. Antarct., p. 176, 1847. 
Host: Luzula crinita Hook. f. The host is confined to the Auckland 
and Campbell Islands. 
(7.) Aecidium Discariae Cke., Grev., vol. 14, p. 89, 1886. 
This form belongs to the cycle of Uromyces Discariae G. H. Cunn. 
APPENDIX: FUNGI PARASITIC UPON THE UREDINALES. 
In the past numerous fungi belonging to c м genera ае been 
recorded as parasitizing the various spore- of the Uredinales : 
Phycomycetes : Olpidium (= Olipidiella), 
Ascomycetes : Mycosphaerella (= Sphaerella). à 
Fungi Imperfecti: Sphaeropsidales—Phyllosticta ; Ascochyta ; Darluca. 
Нурһошусебев-- -Cladosporium ; Fusarium; Fusoma ; Macrosporium ; 
Oos ; Ramularia; Tuberculin 
Бом. шапу of these will later prove to be merely saprophytic, 
their contiguity with a rust upon the Me host-plant leading to the belief 
that they were parasitic upon the rust. 
far only the two species described below have been collected in New 
Zealand ; Darluca is exceedingly common, especially on the uredosori of 
species are included under the Fungi Imperfecti, the former belongi ng 
to the Sphaeropsidales (Sphaerioidaceae-Hyalodidymae), the latter to "ihe 
Hyphomycetes (Tuberculariaceae-Amerosporae).
