117 P. galiorum, Lk. I. iEcidia hypophyllous, small, short, reflexed at summit; spores subglobose or broadly oval, smooth, 15-21 /*. II. (Not yet found in Illinois). III. Amphigenous; sori usually scattered singly on ieaves and stems, round or somewhat elongated, teleutospores irregular, elongated, mostly oblong or clavate-elliptical, smooth, apex strongly thickened, obtuse or variously pointed, sometimes broadly truncate, usually narrowed to the base, 18-21 by 30-45 ^; pedicels hyaline, about the length of the spore. Single celled teleutospores are rather commonly found. On Galium concinnum and G. triflorum.

P . tenuis, Burrill. I. Hypophyllous, rarely also epiphyllous; secidia clustered in little irregular groups or sparsely scattered, very small, short, the narrow border irregularly lacerated and recurved; spores subglobose, very minutely tuberculate, 14 to 18 i*. (Mcidium tenue, Schw.). III. Hypophyllous; spots small, often confluent, mostly yellow with a broad blackish center; sori sometimes scattered, usually confluent, effused, slightly convex, covered by the epidermis, dull grayish black; spores oblong-clavate, slightly constricted, usually angular or variously and conspicuously pointed, 15 by 40 p.; pedicels hyaline or slightly colored, half as long as the spore. On leaves of Eupatorium ageratoides.

P . kuhnice, Schw. II and III. Amphigenous; sori not prominent nor compact, often ragged from the uneven height of the spores. II. Uredospores with the teleutospores, sub-globose to oblong, echinulate, yellowish-brown, 16-27 by 27-30 n. III. Teleutospores quite uniform, rounded at both ends, broad, with a very short, nearly hyaline apiculus and sometimes a similar projection on the side of the lower segment, thick walled, dark colored, smooth, 30 by 44 t±\ pedicels as long as 90 p. On Kuhnia eupatorioides.

P. conoclinii, Seymour. II and III. Mostly hypophyllous; spots small, purple, often confluent over large areas, becoming pale; sori scattered, sparse or very numerously associated, not often confluent; uredosori cinnamonbrown; teleutosori dark reddish brown; uredospores sub-globose to oval, sharply echinulate, 18-27 //; teleutospores broadly oval, little constricted, ends rounded, wall thick warty, 27 by 32-42 /±; pedicel nearly hyaline, firm, crooked, very long, about three times length of spores. On Conoclinium coelestinum: Pine Hills, Union Co., Sept. 11, 1882. Coll. P . S. Earle.
