Aecidium balsameum, (Pk.) Diet. 



NOTE. It has been conjectured that this species is connected with a species 

 of Colyptospora common on Vaccinia in North America since Aecidium 

 columnare A. & S. closely related morphologically was shown by Hartig, Allg. 

 Forst& Jagdzeit. 1880 (see Bot. Zeit. 38: 618) to belong to Calyptospora 

 Goeppertiana, J. Kuehn. The teleutosporic stage of Aecidium pseudo-col- 

 umnar e, J. Kuehn, Hedw. 23: 1 68, Nov. 1884,3 species still more closely 

 related to Aecidium balsameum is not known. See also notes under Aecidium
