obtained indistinguishable in microscopic structure from those 
of Sclerotinia Libertiana. This has already been shown in con- 
nection with the lettuce disease. It was also shown there, how- 
ever, that the form and manner of production of the sclerotia is 
highly characteristic and not affected by the substratum. There 
is, in short, no reason whatever for supposing, from this case, 
any connection between Botrytis and Sclerotinia except their 
occurrence in the same house. The entire distinctiveness of the 
two forms is nowhere more easily demonstrated than in such a 
case as this.
