149 clustered, short-cylindrical, becoming coarsely divided and widely spreading, pseudoperidium thin but firm; spores irregular, mostly elliptical, epispore rather thick, tuberculate, 12-15 by 15-18 //; spermogonia very few, scattered, above. On Crotonopsis linearis. M. urticce, Schum. Hypophyllous ; spots distinct, brown, border yellow; aecidia densely clustered, short, the narrow border abruptly turned, finely divided ; spores subglobose, epispore rather thin, sparsely tuberculate, 15-21 /;., spermogonia minute, scattered, on the upper side of spot, reddish brown. On Urtica. Coll. C. A. Hart. M. smilacis, Schw. Hypophyllous ; spots large, circular, somewhat effused, pale yellowish, somewhat thickened, secidia irregularly scattered or crowded, short, recurved border wide and rather coarsely divided; spores irregular, mostly angular, elliptical to oblong, epispore thick, conspicuously tuberculate 15-18 by 18-22 j±\ spermogonia numerous, scattered, mostly above, honey-yellow. On Smilax herbecea. Coll. J. C. Arthur. M. trillii, Burrill. Hypophyllous; spots distinct or somewhat confluent, circular, effused, yellowish; secidia densely aggregated around a free central circular space, sometimes with a more or less distinct outer circle later in development, short, pseudoperidium thin, fragile, soon after opening becoming pulverulent; spores subglobose, epispore very thin smooth, 19-24 /*; spermogonia very numerous, rather prominent, scattered, on both sides of leaf. On Trillium recurvatum. Differs from M. convallarice in the more fragile and fugacious aBcidia and in the smooth, very much thinner epispore. M. convallarice, Schum. Hypophyllous; spots distinct or more or less confluent, lemonyellow, scarcely thickened, aecidia loosely clustered, irregular or subcircinate, short cylindrical, recurved border narrow and abruptly turned; spores subglobose or oval, sometimes angular, epispore thick conspicuouly tuberculate, 21-24 by 24-30 n; spermogonia numerous, scattered over the central area of the spot on both surfaces, dark reddish-brown. On Smilicina stellata and S. racemosa.

Genus BCESTELIA, Kebent. Spores one-celled, in chains or vertical rows, without pedicels; sorus inclosed in an elongated, usually tapering pseudoperidium, which protrudes far through the ruptured epidermis of the host, and which becomes deeply split and fringed; with spermogonia. On species of Pomeoe.
