Behenis. a, Teleutospore and mesospore, on Silerie inflata; h, uredospoie and teleutospore, on Lychnis diurna. in orbicular clusters, minute, shortly cylindrical, with whitish torn margin; spores delicately verruculose, orange, 17—26 x 14—20^1, or 15/x 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 fx, with three or four germ-pores. Teleutospores. Sori similar, but black-brown; spores oblong to ellipsoid, rounded at both ends, faintly constricted, surmounted by a small pale apical papilla, smooth, chestnut-brown, 25^—40 x 16—26 yu,; pedicels hyaline, short, deciduous. On Silene inflata (= S. latifolia, S. Oucuhalus) and Lychnis diurna (dioica). Not common. Uredo- and teleutospores, July—October. (Fig. 170.) The description of the spermogones and a3cidia is partly after Schroter, Sydow, and Fischer. The distinction of the secidium of this species from that belonging to Uromyces Behenis is as follows :—Tlie former has sper- mogones and m-edospores, which accompany and follow it, but it is never accompanied by teleutospores. The early secidia of the Uromyces are situated on purplish spots which show above, the later ones are usually.
