J find the septum of the teleutospores almost always comparatively broad 
and dark, far more so than in the majority of Puccinias.

Spermogones. Few, scattered amongst the ecidia, pale- 
yellowish. 
Aicidiospores. Aicidia rarely on the 
leaves, hypophyllous, more often on the 
petioles and stems, densely crowded, caus- 
ing considerable hypertrophy and curva- 
ture, between cup-shaped and pustulate, 
whitish, with a white irregularly torn 
margin; spores delicately verruculose, 
yellowish, 15—22 p. 
Teleutospores. Sori amphigenous, 
scattered, minute, roundish, sometimes 
on the petioles confluent and elongated, 
long covered by the epidermis, black; 
spores ellipsoid to obovate-oblong, gener- 
ally rounded at both ends, not thickened 
above, hardly constricted, minutely reti- 
culate, brown, 25—42 x 14—24; pedicels

This species has no uredospores. Plowright confused together this 
and the Puceinia tumida on Conopodium denudatum (see his synonymy 
on pp. 206, 270). The latter species has no excidia; this partly explains 
his remarks that he was unable to obtain any evidence of the connection 
between the ecidium and the Puccinia. Nevertheless, it appears not yet
