. Cryptogamic plants of the USSR. (Flora sporovykh rastenii SSSR). Plants. Spermagonia epiphyllous, between the cuticle and epidermis, whitish, conical, flattened at base, 120 —135m across, covered by a brownish membrane, the paraphyses, projecting above it. Aecia on systemic mycelium, mm across; peridia cupular, with outwardly flexed fimbriate margins, white; peridial cells almost rectangular, overlapping by the downward projecting wedge-shaped processes; cell walls thick; outer wall cross-striated, 6—9^ thick, outer wall 3 —5/x thick, furrowed in structure, coarsely verrucose. Aeciospore

Aecia on systemic mycelium, mm across; peridia cupular, with outwardly flexed fimbriate margins, white; peridial cells almost rectangular, overlapping by the downward projecting wedge-shaped processes; cell walls thick; outer wall cross-striated, 6—9^ thick, outer wall 3 —5/x thick, furrowed in structure, coarsely verrucose. Aeciospores blunt-angular, 16 —30 X 18 —21 jli; walls evenly thick, about 1m, rarely slightly thicker on one side, verruculose; distance between warts less than 1m; contents colorless. Uredia round, scattered over the entire underside of leaves on whitish- yellowish patches, white, up to mm across, surrounded by a crown of paraphyses, growing together at the base like peridia. Urediospores globoid, ellipsoid, or ovoid, 22 —28 X 15 —25 m ; walls colorless or pale rust-brown, — thick, verrucose; distance between verrucules about pores inconspicuous. Telia hypophyllous, covered by the epidermis, later exposed, whitish, — across, in small groups. Teliospores 30—60X8 —10m, thickly set, like a palisade, cylindrical, rounded at apex, single, later.
