 Aeeidium (sub Peridermio) ornamentale, (Arth.) 



Note. This species was originally described as a Peridermium, but we 

 have here included that genus under Aeeidium. The species cannot how- 

 ever be called Aeeidium ornamentale as there is a species of that name de- 

 scribed by Kalchbrenner in Thuemen, Myc. Univ. 224. 1875 and in Flora 

 5g : 205. i May 1876.

Aeeidium Osmorrhizse, Pk. 



Note. This Aeeidium on Osmorrhiza is considered by Lindroth and by 

 Sydow to belong to Puccinia Osmorrhiza, C. & P., a species whose synonymy 

 is far from clear. See Lindr. Acta Soc. Fauna et Fl. Fennica 22 1 : 17. 1902. 

 Syd. Mon. Ured. 1 : 397. 15 May 1903. For convenience we have included 

 Aecidia on Cicuta and on Pseudoeym of tents to which authors have applied 

 this name. See Lindr. 1. c. 53, 173. 1902. 



In Jour. Myc. 9: 10. 14 Feb. 1903 Kellerman gives an account of a cul- 

 ture in which the spores of this Aeeidium from Osmorrhiza produced teleuto- 

 spores on Cheer ophyllum. A. B. S.
