15, 5917, Sept. 19. 5995; Ogle, Sept. 23,6138. C. alpina: Kane, 
Aug. 380, 1380. 
On Circea Lutetiana the sori are marked, while on C. al- 
ping they are distinct, smaller, and often circinate. 
P, pimpinelle, (Strauss) Lk. 
IL, III. Amphigenous. Sori rather large, round, scat- 
tered, soon naked. Uredospores globose or ovate, minutely 
roughened, thick-walled, 18-21 by 24-27 «; teleutospores broad, 
ends rounded, little constricted, surface roughened with mesh- 
like depressions, 18-21 by 29-35 »; pedicel tyotlini fragile, 
sometimes more or less lateral. 
Spots obliterated, sori subrotund, scattered, amphigenous, spores 
cinnamon, of two forms, ovate and obovate, short pedicelled.—Link, 
Linn. Sp. Plant, VI., P. IL, p. 77. 
On Osmorrhizu longistylis: Fulton, 2269, IL, II. (Wolf); 
Adams, June 30, 5359. O. brevistylis: LaSalle, Sept. 29, 62381. 
Peck (29 Rep. N. Y. State Mus. [1878] p. 73) mentions 
without describing P. osmorrhize, C. & P.. on Osmorrhiza. 
Previously (25 Regi N.Y. State Mus. [1873] p. 112) he des- 
eribes P. wyrrhis, Schw. (N. Am. Fungi, [1834] p. 296) on 
the same host plants. Schréter (Hedw. XIV. [1875] p. 169) 
shows the latter to be the same as P. pimpinellw, Lk. (Spec. 
Plant. If. [1824-25] p. 77). Winter (Rabh. Kryptog. FI. I. 
[1882] p. 212) unites these two with P. chwrophylli, Purton, 
(Brit. Plants III. [1821] No. 1553), and other supposed species 
under the name of P. pimpinelle (Strauss). The above men- 
tioned specimens collected by Wolf were identified by Peck as 
P. osmorrhize, C. & P., but they agree with his description 
of P. myrrhis, Schw.,and with Thiimen’s specimens, including 
those of P. myrrhis, Schw. (Mycoth. Univ. No. 1327), collect- 
ed in New York by Gerard, and P. charophylli, Purton, (My- 
coth. Univ. No. 1229). 
P. galiorum, Lk. 
I. Acidia 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
