Mycorhiza of Fruit-trees.* — Vital Boulet found endophytic myco- 

 rliiza in a large number of fruit-trees in the natural order Rosacea?. He 

 describes the development and appearance of the fungus, and concludes 

 from his observations that it is a true parasite — harmless, as a rule, 

 because the vital parts of the root are not injured, but occasionally fatal 

 to the roots infected. Boulet thinks that the mysterious perishing of 

 fruit-trees may be due to the presence of the fungus in the roots.
