104 MANUAL OF TREE DISEASES 



Abundant growths of the sterile mycelium, which is coarse, 

 loosely matted and reddish brown, cover the affected roots. It 

 also grows over decaying sticks and other matter on the surface 

 of the ground. The mycelial growth has the appearance of a 

 quantity of tangled hair. 



The mycelium spreads through the soil and is transported in 

 various ways by cultivating tools. It is said to display excep- 

 tionally destructive tendencies in wet, badly drained soils and 

 diu-ing rainy periods. Loosening the soil, deep plowing and 

 drainage are said to reduce losses by i-etarding the spread of the 

 mycelium in the soil.
