Hypophyllous, growing among the secidia. jEcidiospores. iEcidia hypophyllous, seated on pale-yellow spots, solitary or in small round or elongated clusters, shortly cup-shaped, with a whitish, torn, revolute margin; spores densely and minutely verruculose, yellow, 14—22 p. Uredospores. Sori amphigenous, scattered or circinate, girt by the ruptured epidermis, minute, pulverulent, pale-brown ; spores globose to ovate, distantly echinulate, at length pale- brown, 20—30 x 18—26fx\ epispore 1^—2iyu, thick, with three or four germ-pores. Teleutospores. Sori similar, but per- sistent and darker or blackish-brown; spores subglobose to obovate, rounded or truncate and thickened above, where the wall is dark and 7—11^ thick, sometimes with a colourless papilla, smooth, brown, 25—38x18—27 /* ; pedicels brownish, persistent, thick and as much as 40—70 /x long. ()n leaves and stems of Faba vulgaris, Lathyrus pratensis (?), Pisum sativum, Vicia Cracca, V. sativa, V. sepium. iEcidia in April, May; uredospores from May, teleutospores from July onwards, lasting through the winter on the dead stems.
