Teleutospores. Sori hypophyllous, on discoloured roundish 
spots, minute, circinate, but mostly confluent in large patches 
as much as 5 mm. diam. which remain for a long time covered 
by the epidermis, compact, blackish-brown; spores clavate or 
subfusiform, rounded or rarely somewhat conical above, very 
c 
Fig. 96. P. Cnici-oleracei. Teleutospores, on C. lanceolatum., 
much thickened (5—10 »), constricted, attenuated below, 
smooth, yellowish-brown, 838—56 x 14—21 y; pedicels yellowish- 
hyaline, thick, persistent, as much as 50 u long. 
On Cirsium lanceolatum, Carduus crispus (?). August— 
October. Not uncommon on the former. (Fig. 96.) 
This is one of the species in which the upper cell separates from the 
lower one. It is doubtful if Pucetnia Syngenesiarum (Cooke, Handbook, 
p. 499; Micr. Fung. p. 206) belongs entirely here, as the figure in the 
latter work (pl. 4, f. 64) does not give the true form of the teleutospore ; 
but the majority of the specimens issued by him under that name are this 
species. It is very questionable if this species occurs on Carduus crispus, 
on which it is recorded by Plowright. 
DISTRIBUTION : in a few places in Europe.
