Remarks. /Ecidium Tussilaginis Pers. was found .to have a genetic 
relation to the present species by Nielsen (2) in 1877. The connection was 
later verified experimentally by PLOWRIGHT, Winter, Klebaiin and 
Tranzciiel. 
According to Schroeter, the .Ecidium stage of this fungus occurs not 
only on Tussilago Farfara but also on Petasites albus and P. officinalis.
