102 FUNGOID DISEASES 



"seed pods/' but also on the stem. The pod

\T. ScLEROTiUM \}i%Y.k^Y.{Sclerotinia libertiana ; 

 Sclerotinia s clerotiorimi , Massee). Class : As- 

 COMVCETES ; Order : Pezizales. 



* Rape, swedes, and turnips are attacked In parti- 

 cular. The mycelium Is only able to enter the 

 host after being nourished for a time saprophytl- 

 cally. A description of this fungus Is given on 

 page 6^, under sclerotlum disease of clover. 



Since the sclerotia are capable of resting for a 

 long time, and the fungus Is able to grow as a 

 saprophyte, little can be done to prevent attack. 

 Liming Is to be recommended.
