 times in connection with preserved fruits. The mycelium 

 is in contact with its source of food-supply, which is 

 called the substratum. 



From the prostrate mycelium numerous erect branches 

 arise, each branch bearing at its tip a large globular cell

 therefore, is a sporangium, and the erect branch is a sporo-
