(6) F. radicicola caused no rot at 12° C. A constant storage tempera- 

 ture below 50° F. would prevent the action of F. radicicola, F. eumartii, 

 and F. oxysporum. 



(7) The following species of Fusarium are added to those known to 

 cause tuber-rot through wound infection: F. radicicola Wollenw.; F. 

 eumartii, n. sp.; F. oxysporum Schlecht.; and F. hyperoxysporum 

 Wollenw.
