Rosellinia ligniaria (Nitschke) has been found to attack living ash 

 trees by Mr. W. Carruthers.

 bulbs. 



Rosellinia bothrina (B. & Br.) Sacc. is the cause of the tea root rot.

 and shrubs. 



The works most freely drawn upon regarding parasitic species are the 

 following:

All species figured and described in this paper have been verified by 

 Dr. Charles H. Peck, or compared with specimens in the New York State 

 Museum by H. D. House, acting State Botanist of New York. I take this 

 opportunity to express my thanks for their assistance. 



For valuable material and aid in formulating this paper, I am greatly 

 indebted to Prof. J. M. Van Hook of Indiana University.
