MUSHROOM GROWING 



agree with this view. I have since grown 

 the Tricholoma satisfactorily in a small bed 

 of well fermented leaves — maple, birch, and 

 beech. During the past year or two Ma- 

 truchot, in Paris, has also announced the suc- 

 cessful culture of this species. From none 

 of the experiments made, however, is there 

 any indication that this species will excel 

 Agaricus campestris in yield, and it is not 

 so satisfactory for marketing and shipping. 

 The fact that it may be grown upon leaves — 

 which as a substratum are free from all the 

 objections to compost — and the further ca- 

 pacity to fruit at a wider range of tempera- 

 tures, suggest its possibilities. 



The two species above mentioned may 

 frequently be found upon the markets of Eu- 

 rope, as also of Asia (notably in China and 

 Japan, I am informed) and where they oc- 

 cur in sufficient quantity to be of any eco- 

 nomic importance they are invariably con- 

 sidered edible. 



On the markets of Munich, T. gamhosum 

 was sold in 1 90 1 to the extent of about 25,000
