FUNUI 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.
