338 PROTOZOOLOGY 



An enormous number of mycetozoan genera and species are 

 known. The order is divided here into two suborders. 



Spore develops into myxoflagellate; myxamoebae fuse completely and 

 form Plasmodium Suborder 1 Eumycetozoa 



No flagellate stage; myxamoebae grouped prior to spore-formation, but 



do not fuse to form a true Plasmodium 



Suborder 2 Sorophora (p. 341) 



Suborder 1 Eumycetozoa Zopf 



Spores develop within sporangia 

 Spores violet or violet-brown 

 Sporangia with lime 



Lime in small granular form Family 1 Physaridae

 sions filled with granules of lime.
