Characterised by the warted teleutospore, amongst the 
species on Carduus. 
Puccinia cardui-pycnocephali, Sydow. 
Uredospores. Sori produced on the under surface of the 
leaves, scattered, minute, pale brown, not causing dis¬ 
coloured spots ; spores globose or subglobose, very minutely 
echinulate, 22—26 p, diam. 
Teleutospores. Sori on the under surface of the leaves, 
scattered, and almost hidden by the down on the leaf, 
not forming discoloured spots, brown, somewhat darker 
than the uredospore sori; spores oblong, tip rounded, not 
thickened, not at all, or very slightly constricted at the 
septum, base rounded, epispore thin, smooth, pale brown, 
38—50 X 16—23 (X, pedicel hyaline, slender, deciduous, 
up to 40 p long. 
On living leaves and stem of Carduus pycnocephalus, 
L. First observed in this country by Dr. Eng. Mayor, at 
Sidmouth, July, 1907. During August of the same year, 
I collected the fungus in abundance, on the same host, 
along the coast-line between Eastbourne and Hastings. 
Previously only recorded from Italy on C. pycnocephalus, 
L. - 
Some specimens collected agreed well with the diagnosis 
given above, while other specimens approach very closely 
to a second species of Puccinia, described by Sydow as' para¬ 
sitic upon C. pycnocephalus, L., and called P. galatica, 
Sydow, of which the following is a diagnosis : 
Uredospores. Spores found mixed with the teleutospores, 
globose or subglobose, pale brown, minutely echinulate, 
22—28 p diam. 
Teleutospores. Sori occurring on both surfaces of leaves, 
not forming discoloured spots, scattered or gregarious, 
minute, black, becoming pulverulent; spores elliptical, 
ends rounded, tip not thickened, generally slightly con¬ 
stricted at the septum, dusky brown, epispore 'about 3 p 
thick, delicately punctate, 30—^45 x 22—28 p, pedicel 
hyaline, slender, up to 30 p long. 
Distinguished from P. cardui-pycnocephali, Syd., by the 
slightly smaller, darker coloured, thick-walled teleutospores.
