On Circd'a Lntctiana the sori are marked, while on C. al- 

 pina they are distinct, smaller, and often circinate. 



P. pimpinellse, ( Strauss ) Lk. 



II.. 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 2V)-35 ^x pedicel hyaline, fragile, 

 sometimes more or less lateral. 



Spots obliterated, sori siibrotund, scattered, amphigenous, spores 

 cinnamon, of two forms, ovate and obovate, short pedicelled. — Link, 

 Linn. Sp. Plant, VI., P. II., p. 77. 



On Osmorrhiza longistylis: Fulton, 2269,11., III. (Wolf); 

 Adams, June 30, 5359. ' 0. hreristylis: LaSalle, Sept. 29, 6231. 



Peck (29 Rep. N. Y. State Mus. [1878] p. 73) mentions 

 without describing P. osinorrhizw, C. & P.. on Ostnorrhiza. 

 Previously (25 Rep. N. Y. State Mus. [1873] p. 112) he des- 

 cribes P. mijrrhis. Schw. ( N. Am. Fungi. [1834] p. 296) on 

 the same host plants. Schroter (Hedw. XIV. [1875] p. 169) 

 shows the latter to be the same as P. pimpinella^ Lk. (Spec. 

 Plant. II. [1824-25] p. 77). Winter (Rabh. Kryptog. Fl. I. 

 [1882] p. 212) unites these two with P. clia'rophjjUi, Purton, 

 (Brit. Plants III. [1821] No. 1553), and other supposed species 

 under the name of P. pimphiellce (Strauss). The above men- 

 tioned specimens collected by Wolf were identified by Peck as 

 P. osmorrhizcp, C. & P., but they agree with his description 

 of P. nii/rrJiis, Schw., and with Thiimen's specimens, including 

 those of P. myrrh is, Schw. (Mycoth. Univ. No. 1327), collect- 

 ed in New York by Gerard, and P. cha'rophyUi, Purton, (My- 

 coth. Univ. No. 1229). 



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
