CHAPTER IX.— MODE OF LIFE OF THE MYCETOZOA. 453 
Plasmodiophora shows that it is, in the terminology employed in the Fungi, an en- 
dophytic parasite which greatly deforms its host. Vampyrella and the forms with 
a similar mode of life must no longer be termed parasites; they devour other 
organisms wholly or partially, absorbing the objects which they admit into their sub- 
stance by the same or nearly the same movements as those by which plasmodia 
take in their solid ingesta.
