Type-MUCOR MUCEDO. 



This is a common mould fungus which grows on 

 living plants, decaying vegetable substances and the 

 surface of organic solutions (glue or saccharine 

 fluids). The fungus derives its nourishment from the 

 material on which it grows. 



DESCEIPTION OF A MATUEE MUCOE. 



The vegetative part — the mycelium — consists of 

 copiously branched irregularly septate sacs, each of 

 which contains streaming protoplasm and many 

 nuclei. Each branch, whether septate or unseptate, 

 is called a hypha. 



From these hyphse arise the straight, unseptate, 

 unbranched, fruiting branches, called Conidiophores 

 (or gonidiophores) which are also multinuclear, and 

 in these the streaming of the protoplasm can be 

 specially well observed. 



Each filament or conidiophore bears a globular 

 head — the Sporangium. The conidiophores are an 

 inch or more in length, and turn towards the source 

 of light. The sporangium is round, yellow or brown, 

 the contents being yellowish-brown protoplasm, and
