FUNGI 



153 



85. Mushrooms. This 

 name is a very indefinite 

 one; sometimes applying 

 to any of the fleshy Fungi 

 of the umbrella form, and 

 sometimes including among 

 such forms only those that 

 are edible, the poisonous 

 ones being spoken of as 

 toadstools. For our pur- 

 pose, no exact definition 

 of the word is necessary, 

 it being used as the com- 

 mon name of a group of 

 forms with which the stu- 

 dent should be somewhat 

 familiar.
