MYXOTHALLOPHYTA 



Fungus-likc organisms without chlorphyll, regarded by some as animals: 

 intermediate, in some respects, between animals and plants and hence called 

 Mycetozoa by Rostafinski. In their vegetative condition, they consist of naked 

 masses of protoplasm with many nuclei, the mass of protoplasm being called 

 the Plasmodium which creeps about on the substrata changing in form and 

 thrusting out processes called pseudopodia whicii may later coalesce. After
