THE MYXOMYCETES OF PICTOU COUNTY. — MOORE. l75i 



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

 united together to form a simple or branclied stock. The other, 

 amoebse creeping up on this finally come to rest and. form a,n 

 aggregation of free spores. 



The distinction between these organisms and the true 

 Myxomjcetes appears to be an essential one, and consists in 

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

 ■ coalescing amcebse retaining throughout their individuality. 



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

 grapli of the gToup, and, adopting the view of the latter that the 

 life history of the Myxoniycetes 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 fonned the basis of all subsequent systematic work on 

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