DUGGAR—RHIZOCTONIA SOLANI 9 
‘‘mopo’’ fungus bears no resemblance to Acrostalagmus al- 
bus, to which “Ча toile" in France had been occasionally re- 
ferred. On the other hand, cultures of the ‘‘Vermehrung- 
spilz’’ obtained from Amsterdam agreed closely with the or- 
ganism isolated from Cinchona seedlings. Infection experi- 
ments with Ше “торо” fungus were carried out both on Cin- 
chona seedlings and on seedlings of the plants previously 
enumerated as affected. In all cases positive results were ob- 
tained. 
Summary and Discussion—From the reviews and discus- 
sion it seems justifiable to conclude that the common seed- 
bed fungus in Germany and in France is identical with the 
damping off fungus which has been frequently studied in this 
country since the investigations of Atkinson (’92). I have 
given the evidence upon which the conclusion is based that 
the damping off fungus of the United States is Kiihn’s Rhi- 
zoctoma Solani (Corticium vagum B. & C.), the cause of im- 
portant potato diseases and of other types of disease in a 
variety of host plants. The work of Rant enables us to in- 
clude in this category of diseases due to Rhizoctonia Solani 
the disease of Cinchona seedlings and of other plants in Java. 
In establishing these points it is not necessary to consider 
the earlier and less complete reports upon ‘Іа toile’? and the 
‘‘Vermehrungspilz’’ but particularly the papers of Aderhold 
(797), Sorauer (799), Beauverie (99), and Ruhland (’08).
