TREE MUSHROOMS 



Among the fungi growing on decaying stumps and 

 trees is a form kno\\n as the o}'ster mushroom. It was 



given this name 

 because its shape 

 is much like that 

 of the oyster shell. 

 These m. u s h - 

 rooms grow in 

 clusters and some- 

 times overlap each 

 other. They are 

 often irregular in 

 shape because of 

 this crowding. A 

 single mushroom 

 may be five or 

 six inches broad, 

 "^lliey grow side- 

 ways from the tree 



The Oyster Mushroom.
