1. That the mushroom is the Ectotrophic Mycorhiza found on 

 Akamatsu (Pinus densiflora S. et Z.) as a parasite. 



2. The Akamatsu has both Ectotrophic and Endotrophic Mycorhiza. 



3. The Ectotrophic Mycorhiza that generally takes the Akamatsu 

 as its host is never found on the pine root where the mushroom is found 

 as the parasite. 



4. No foundation exists for the old belief that granite rocks are 

 specially favourable to the growth of mushrooms. The growth of the 

 mushroom has no particular relation to the existence of granite rocks. 



5. The mushroom can easily be grown on wood land, where the 

 pine can only send out their rootlets to the surface soil, owing to the 

 rocky nature of the underlying layer, etc. Where the land is naturally rich, 

 such rootlets must be forced by human agency to stretch out near the 

 surface soil in order to produce mushrooms. 



6. The spores of the mushroom should be sown immediately after 

 the harvest.
