ON COMPOSIT 187 
Teleutospores. Sori amphigenous, on brown orbicular spots, 
densely gregarious and confluent in roundish clusters, 3—6 mm. 
broad, occupying the whole spot, often circinate, long covered 
by the epidermis, at length rather pulverulent, deep-brown ; 
spores ovate to oblong, with a very minute paler apical papilla, 
hardly constricted, rounded or slightly attenuated below, 
smooth, pale-brown, 30—45 x 16—24; pedicels hyaline, very 
short. 
On Senecio Jacobaea. August—November. Not common. 
Closely allied to the preceding species, but said to be distinguished by 
its paler, narrower and longer spores which are provided with a smaller * 
apical papilla. Moreover, the sori are said to be less dark in colour (not 
darker as Plowright states), and are distributed more uniformly on both 
leaf-surfaces, Nevertheless, I suspect they are identical.
