MUSHROOM GROWING 



The well penetrated bricks should be 

 dried gradually, but considerably, and to 

 the extent that no more growth may occur. 

 This is preferably accomplished under 

 cover; and the spawn should subsequently 

 be stored where it is both cool and dry. A 

 cool, moist cellar would encourage a pro- 

 duction of little mushrooms upon the bricks 

 and it seems that a very warm situation is 

 more injurious to the vitality of the product. 



Vitality of spawn. During the past few 

 years I have made many tests of spawn 

 of various ages, and of material which had 

 been stored in various ways. The results 

 indicate that under ordinary circumstances 

 mushroom spawn is unquestionably so badly 

 injured after being stored for a period of 

 one year as to be unfit for commercial pur- 

 poses. There are persons who claim that 

 they have successfully carried spawn over 

 from one season to another. This may be 

 true, but the conditions must have been un- 

 usually favorable. I have never had the 

 opportunity of testing commercial spawn
