(6) F. radicicola caused no rot at 12 0 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.
