Cunnincuam.—The Uredinales, or Rust-fungi, of New Zealand. 27 
0. Spermogones hemisphaerical, flattened, without ostiolar filaments. 
L Caeomata erumpent, without peridia or paraphyses, pulvinate. 
Caeomatospores globose ; catenulate ; epispore hyaline, finely verruculose ; 
edosori without peridia, pulverulent, erumpent. Uredospores 
borne singly on pedicels, intermixed with capitate paraphyses ; epispore 
III. Teleutosori indehiscent. Teleutospores compacted laterally into 
flat waxy irregular dark-coloured layers, unicellular, prismatic or elliptical ; 
epispore coloured, smooth ; germ-pore apical, obscure. 
. Distribution: World-wide. Two indigenous species occur in New 
aland. 
The teleutospores form conspicuous chestnut-brown waxy crusts, often 
15 mm. long, on the stems and leaves of the hosts. They are closely 
compacted together, and in consequence appear prismatic in shape.

П. Uredosori amphigenous, chiefly hypophyllous, scattered, pulverulent, 
elliptieal, 0-2-0-5 mm. long, reddish - orange when fresh, yellowing wit 
age, surrounded by the ruptured epidermis mixed with numerous hyaline 
capitate paraphyses. Spores subglobose or elliptical, 17-24 x 12-17 mmm. ; 
epispore hyaline, closely and coarsely verruculose, 1-5-2 mmm. thick ; 
germ-pores scattered, 3—4, obscure. 
1. Teleutosori hypophyllous, scattered or aggregated in small irregular 
groups, subepi ermal, minute, 0-3-0-5 mm. diam., at first chestnut-brown, 
ecoming black. Spores prismatic, 22-32 x 6-12 mm.; apex rounded 
or truncate, slightly (2-3mmm.) thickened; epispore smooth, yellowish, 
lmm. thick: germ-pore apical, obscure.

Distribution: Japan; Australia. 
The host is indigenous, and is fairly widely distributed ; it occurs also 
in Australia, Tasmania, and New Caledonia. (Cheeseman, 1906, p. 74.) 
Only the uredospores have been collected in New Zealand, but both 
stages have been recorded from Australia by McAlpine (1906, p. 191) as 
M. Hypericorum Schroet. 
Sydow has suggested (Mon. Ured., vol. 3, p. 386, 1912) that Aecidium 
disseminatum Berk. is probably the uredo stage of this species ; but McAlpine 
(1906, p. 200) had specimens of an Aecidium on Hypericum j icum 
compared with the type of Aec. disseminatum at Kew, when they were found 
to be identical.
