Fig. 170. P. Behenis. a, Teleutospore and mesospore, on Silene inflata; 
b, uredospore and teleutospore, on Lychnis diurna. 
in orbicular clusters, minute, shortly cylindrical, with whitish 
torn margin; spores delicately verruculose, orange, 17—26 x 
14—20 pw, or 15 diam. 
Uredospores. Sori amphigenous, scattered or circinate, 
sometimes confluent, on paler spots, minute, cinnamon-brown ; 
spores subglobose to ellipsoid, echinulate, pale-brown, 20—26 x 
17—22 yw, with three or four germ-pores. 
Teleutospores. Sori similar, but black-brown ; spores oblong 
to ellipsoid, rounded at both ends, faintly constricted, surmounted 
by asmall pale apical papilla, smooth, chestnut-brown, 25—40 x 
16—26 yw; pedicels hyaline, short, deciduous. 
On Silene inflata (=8. latifolia, 8. Cucubalus) and Lychnis 
diurna (dioica). Not common. Uredo- and _teleutospores, 
July—October. (Fig. 170.) 
The description of the spermogones and acidia is partly after Schroter, 
Sydow, and Fischer. The distinction of the ecidium of this species from 
that belonging to Uromyces Behenis is as follows :—The former has sper- 
mogones and uredospores, which accompany and follow it, but it is never 
accompanied by teleutospores. The early xcidia of the Uromyces are 
situated on purplish spots which show above, the later ones are usually
