other authors) appear first on yellow spots, and are slowly followed by the 
zcidia towards November or earlier; at that time of the year the Daisy 
plants are generally in a condition of vigorous, though slow, growth. 
There is a species of Pucctnia (P. distincta McAlp.) found on Bellis 
perennis in Australia, but this bears acidia and teleutospores on the same 
leaves ; there are no uredospores. Since the Daisy is not a native of that 
country and is grown there from seed imported from England and 
Germany, it would seem that the fungus is imported with the seed ; yet in 
our country and in Germany, the Daisy never bears teleutospores. The 
teleutospores of the Australian species closely resemble those of P. obscura 
on Luzula, and like them are often intermixed with numerous mesospores ; 
moreover, they often grow amongst and round the ecidia, apparently 
always from the same mycelium. Can it be that the European fungus has 
been introduced with the seed and has adapted itself to an autcecious life ? 
This, however, seems hardly probable, since Luzula campestris is found in 
Australia, but the Puceinia which attacks it there (P. tenuispora McAlp.) 
is different from either of our European species.

Uredospores. Sori amphigenous, on irregular and confluent 
reddish-brown or blackish-brown spots, scattered, oblong, long 
covered by the epidermis, ferruginous; spores oblong-ovate to 
pyriform or clavate, irregular, smooth, rarely aculeolate at the 
summit, rusty-yellow, 830—44 x 12—15 4; epispore colourless, 
thick, without germ-pores. 
Teleutospores. Sori similar, but soon naked, compact, 
blackish-brown; spores clavate, much thickened (10—25 ) 
above where they are rounded or rarely more or less obliquely 
tapering, gently constricted, tapering gradually downwards, 
smooth, brown, 44—80 x 16—24 w; pedicels hyaline, persistent, 
about as long as the spore or shorter.
