THE MYXOMYCETES OF P1CTOU COUNTY. MOORE. 175 



amoebae do not give rise to spores, but soon become rigid and 

 united -together to form a simple or branched stock. The other 

 amoebae creeping up on this finally come to rest and form an 

 aggregation of free pores. 



The distinction between these organisms and the true 

 Myxomycetes appears to be an essential one, and consists in 

 this that in the former no true plasmodia are produced, the 

 coalescing amoebae retaining throughout their individuality. 



In 1875, Rostafinski, a pupil of deBary, published a mono- 

 graph of the group, and, adopting the view of th latter that the 

 life history of the Myxomycetes indicated a wide separation 

 from the fungi, he suppressed that name altogether and adopted 

 instead deBary's Mycetozoa. As this monograph has to a large 

 extent formed the basis of all subsequent systematic work on 

 the group, I insert an outline of Rostafinski's system :
