On leaves and petioles of Pyrola, (Cape Elizabeth, E. C. B.) This is a most distinct and unmistakable species, and apparent- ly undescribed. The external appearance, habit and color, is very much that of Puccinia Umbilici, Guep. Puccinia Xanthii, Schw. Uredo-form.—Uncertain. Septate form—Spots orbicular, pallid, on the opposite surface yellowish brown with a pallid margin. Sori compact, large, concentric, confluent, or- bicular, forming a blackish brown, convex mass. Spores elliptic, slightly constricted, brownish; peduncles elongated. On leaves of lister. (WestbrookE. C. B.) On leaves of Xanthium strumarium. (Schweinitz.) (Schweinitz Syn. Car. 500. Fung. Am. Bor. No. 2927.) Podisoma, Link. Peduncles extremely long, agglutinated by gelatine into a common stem, spreading out above into a clavariaeform mass. Spores mostly uniseptate. Gymnosporangium is represented in South Carolina, and besides Podisoma'- Juniperi a distinct form which has been named Podisoma macropus is known from the same State. Only the true Podisoma Juniperi has yet been found in Maine. Podisoma Juniperi, Er. Orange, clavariaeform, somewhat branched; stroma simple; spores very long, lanceolate, filled with elliptic granules. On living branches of Juniper, (Cape Elizabeth, E. C. B.) (Schwz. Fung. Am. No. 3095.) The spores are veiy much longer than in the form named Podisoma macropus, Schw., which has been referred to this species. They are longer than in British specimens, which again are longer than in P. macropus. The figure in this, as in all the species fig- ured, are from American specime
