PLATE XVII. 
Camera lucida drawings showing chlamydospore formation in old myce- 
lium after it had passed through the oidial stage, X 1,500. a, a terminal 
chlamydospore; 6, an intercalary chlamydospore, showing how it is set 
free by the disintegration of the empty portion of the parent hypha; 
c, two intercalary chlamydospores formed near together, showing the dis- 
integration of the parent hypha. The lower chlamydospore has abandoned 
its original end wall, the protoplasm having contracted further and formed 
a new limiting membrane about itself at this point.
