146 M. lysimachice, (Schw.) Wallr. Hypophyllous (also on the petioles); spots distinct, yellowish, scarcely thickened; secidia somewhat circinate, short, the recurved border very narrow; spores subglobose, epispore thick, conspicuously tuberculate, 21-24 by 22-27 /J.; spermogonia few, central above. On Lysimachia ciliata. The above description is taken from specimens on Lysimachia ciliata, and agrees, save in the irregular circinate arrangement of the secidia, with the specimens in Rabenhorsts' Fungi Europaoi No. 391. A specimen from Wisconsin on L, lanceolata is distinct, especially in the characteristics of the spores, but otherwise as well. It is not known what the Schweinitzian Mcidium lysimachice is. If the same as Sehleetendal's Cceoma lysimachice the second authority for the name should be Schweinitz; if different, the question arises as to which name shall be allowed to stand. At all events, there does not seem to be good reason for writing as is sometimes done JEcidium lysimachice, Lk.

M. pentstemonis, Schw. Hypophyllous; spots definite, purple, yellow-bordered, usually small, somewhat thickened; secidia clustered, short, the deeply recurved border rather coarsely split; spores subglobose, inconspicuously tuberculate, 18-21 /J. ; spermogonia few, central in the spots on both sides of leaf. On Pentstemon pubescens.

M. lycopi, Gerard. Hypogenous; spots circular, distinct or more or less confluent scarcely thickened, purplish-brown; aesidia on the leaves mostly circinate, often in a single circular row, sometimes by the confluence of the spots loosely and irregularly scattered, on the petioles and stems irregularly crowded, short, recurved border abrupt and much torn; spores subglobose, epispore thin, tuberculate 15-18 v; spermogonia few, centrally clustered above, reddish-brown. On Lycopus Europceus. Differs from Gerard's description' in the arrangement of the secidia and less swollen spots.

M. myosotidis, Burrill. Hypogenous; aecidia uniformly distributed over the leaf, mostly somewhat densely crowded, rather large, somewhat prominent, the recurved border w.de and rather coarsely divided; spores subglobose or elliptical, epispore thick, conspicuously tuberculate, '15-18 by 1^-22 /Jt; spermogonia numerous, uniformly scattered over both surfaces of the leaf, reddish-yellow. On Myosotu verna.
