220 PROTOBASIDIOMYCETES [CH. 



Coleosporiaceae 



The outstanding character of the Coleosporiaceae is the method of 

 germination of the unicellular teleutospore which undergoes septation directly 

 and, in Coleosporium and Ochropsora, without the protrusion of a pro- 

 mycelium ; in Zaghouania the contents of the teleutospore divide within 

 the teleutospore-wall to form four cells, but emerge before the basidiospores 

 appear. 



The aecidia are cup-shaped in Ochropsora, but in Coleosporiitm and 

 Zaghouania they are of the peridermium type with a cylindrical, more 

 or less inflated peridium ; this elaborate type of aecidial sorus makes it 

 impossible to regard the family as primitive though it may perhaps have 

 branched off early from the line leading to the commoner type of rust.
