A MUSHROOM 71 



should be removed (to be used, if necessary, for covering the bed), and the remainder 

 of the manure made into a heap. After two days, the latter should be carefully 

 turned so as to mix the outside portions with those inside, and the process repeated 

 two or three times on alternate days. Having made the bed, break each of several 

 cakes of spawn into six pieces and insert them edge downwards, so that they are 

 closely in contact with the manure on all sides. Place two or three similar pieces 

 in seed-pans filled with manure, and plunge them in the centre of the bed until the 

 edge of the earthenware projects about an inch above the surface. This must then 

 be covered with light loam, which forms the " landing " of the bed, until the manure 

 is all covered to the depth of about an inch. A temperature of 70 Fahrenheit is 

 that which must be generated at the bottom of the mushroom bed. 



DlEECTIONS TO THE PUPIL 



(5) Write down the various parts of the mushroom which you can 

 identify, including the "cap" and stalk. Make a drawing of the 

 fungus as seen from the side, and label the parts. 



(6) Break off the head or cap : draw its upper and under sides, and 

 describe them in your notes. 



{ 7) Take a quarter of the cap : break it across and make a sketch 

 showing the gills in section.
