10 FUNGOID DISEASES 



branches and re-branches, ultimately forming the 

 mycelium which is capable of unlimited growth under 

 favourable conditions. Many spores are capable of 

 germination after passing through the body of an 

 animal ; the wall of the spores having resisted the 

 effect of the digestive juices. This is a point of 

 great importance, and one that should never be lost 

 sight of in combating the attack of any particular 

 fungoid disease.

Reproduction. — We have just seen that quite a 

 variety of spores are formed, by the different fungi, 

 for the purpose of reproduction, some forming one 

 kind, somie another ; but what is even more inter- 

 esting is the fact that the same fungus may form 

 more than one kind. Many examples might be 

 given, but perhaps one of the most striking amongst 

 parasitic fungi is Piiccinia grauiinis (rust), which
