4&. lycopi, Gerard. 
Hypogenous. Spots circular, distinct, or more or less con- 
fluent, scarcely thickened, purplish brown; ecidia 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, 15-19 »; spermagonia few, centrally clustered 
above, reddish brown. 
Spots yellow; subiculum more or less thickened; peridia short, 
scattered or crowded, margin crenate; spores pale yellow.— Peck, 26 
Rep. N. Y. Mus., p. 78. 
On Lycopus Europeus: Pulaski, May 2, 4424. 
Differs from Gerard’s description in the arrangement of 
the zcidia, and less swollen spots. 
ZS. myosotidis, Burrill. 
Hypogenous. Aicidia uniformly distributed over the leaf, 
mostly somewhat densely crowded, rather large, somewhat 
prominent, the recurved border wide and rather coarsely divid- 
ed; spores subglobose or elliptical, epispore thick, conspicuously 
tuberculate, 15-18 by 18-22 »; spermagonia numerous, uni- 
formly scattered over both surfaces of the leaf, reddish yellow. 
On Myosotis verna: Union, April 12, 4026, 4029, April 18, 
4067, April 17, 4132, April 26, 4306; Jackson, April 27, 4343, 
April 28, 4364. 
The distribution of the ecidia is decidedly different from 
that of Acidium asperifolit, Pers.,as described, as well as from 
the specimens at hand, and similarly different from those 
named Aicidium lycopsidis, Desv., Ay. lithospermi, Thiim., and 
Ay, symphyti, Thiim. The three last are made synonyms of the 
first by Winter, and all are said to be the ecidia of Puccinia 
rubigo-vera. The latter is common in Illinois in wide areas 
where Myosotis does not occur, and no other species of Borrugi- 
nacee has been observed infested with the Acidiwm. 
48. hydrophylli, Peck. 
Hypophyllous. Spots conspicuous, distinct, yellowish; 
ecidia subcircinate, short, recurved border rather wide and
