Hypophyllous, growing among the eecidia. yScidiuspores. .^cidia 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 fj,. 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—26 /J,; epispore 1^—2| /j, 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/u. thick, sometimes with a colourless papilla, smooth, brown, —38 X 18—27 fj,; pedicels brownish, persistent, thick and as much as 40—70 fi long. On leaves and stems of Faba vulgaris, Lathyrun pratensis (1), Pistim sativum, Vicia Cracca, V. sativa, V. sepium. yEcidia in April, May; uredospores from May, teleutospores from July onwards, lasting through the winter on the dead stems.
