PHOTOGRAPH [NG AGARICS 



Use a basket to collect for this purpose. It is well to have tin 



boxes, e. g., cocoa boxes, so thai cadi specimen ran be kept "n 



harmed, wrapped separately in tissue paper ami placed upright 



in the box. Amanitas especially become deformed of lose some of 

 their surface tissue if not properly protected. The specimens can 

 be set upright on decapitated pins in a row as in the photographs 

 in this report. Natural size photographs are by far the best since 

 comparisons are then easily made. For Identification purposes 

 such photographs are much more useful than those taken in the 

 natural surroundings ami reduced in size; the latter may be good 

 pictures but are rarely helpful. Every part and every character 

 used in a description that can be shown in a photograph ought to 

 be brought out; to this end the specimens must be properly arranged 

 and the details emphasized. Besides its value in this respect the 

 photographing of Agarics yields much pleasure and entertainment. 



THE CULTIVATION OF MUSHROOMS 



The history of this business and the methods in use, whether 

 on a commercial scale or for home use, have been so often described 

 that the reader is referred to those works. The best and most com- 

 plete account is to be found in Bulletin No. 85, Bureau of Plant 

 Industry, U. S. Dept. of Agriculture, entitled: The Principles of 

 Muxliroom Growing and Mushroom 8pa/u?n Making, by Dr. B. M. 

 Duggar. For other papers see Bibliography, part (d), and the 

 mushroom books of Atkinson, Hard, Mcllvaine, etc.
