Peculiar Spore-forms in Botrytis. 
conditions, the same sclerotium formed another crop of normal 
conidiophores. This manner of formation would explain the 
occurrence of the definite layer of resting-spores around the 
sclerotium, but the hypothesis is nothing more than a possibility 
deduced from the general morphology of the specimen. 
There still remains the hypothesis that the spores are definite 
resting-spores, produced quite normally and in a definite manner 
at a certain stage of the life history under certain conditions. 
Whatever the morphological value of these resting-spores, the 
case is more especially interesting since they occurred in a state of 
nature and not in artificial culture, so that they may be regarded 
as constituting a normal phase in the life history of the fungus. 
I wish to express my thanks to Mr. F. T. Brooks, of Cam¬ 
bridge, for the assistance he has given me in this work, and to
