158 PUCCINIA 
Uredospores. Sori amphigenous, solitary, minute, cinnamon; 
spores subglobose to ovoid, distinctly 
echinulate, brownish, 24—30 x 21— 
26 pu. 
Teleutospores. Sori chiefly hypo- 
phyllous, similar, but blackish-brown, 
standing singly, scattered over nearly 
the whole leaf-surface ; spores ellipsoid 
to ovoid, rounded at both ends, not 
Hig, 10h. 2: amaiens. Te thickened above, hardly constricted, 
leutospore, on C. palu. very delicately verruculose, chestnut- 
ne ie aa on leaf of brown, 33—48 x 22—30; epispore 
thin; pedicels short, deciduous. 
On Crepis paludosa. Aicidia in June; uredospores, mixed 
with teleutospores, August and September. Yorkshire (Sop- 
pitt), Braemar (Trail), Dolgelly, Wales, and in Ireland. 
(Fig. 109.) 
This species was formerly considered a variety (major) of P. Lapsanae 
on account of the larger spores, but is now kept separate. Dietel proved 
by cultures that the uredo- and teleutospores are connected with the 
eecidial generation. From P. Crepidis, on Crepis virens, it is said to be 
distinguished, not only by the size of the spores, but also by the difference 
in the way in which the ecidia occur on the leaves; the minute, black, 
solitary teleuto-sori seem also different. 
DisTRIBUTION: Northern and Central Europe.
