Host Plants of Thielavia basicola 
299 
(6) Some differences in point of attack and character of sporulation 
of T. basicola on different hosts have been noted. The common occur¬ 
rence of the perithecial stage in close association with the chlamy- 
dospores of a number on different hosts is taken as good indirect cor¬ 
roboratory evidence of Zopf’s connection of this form with T. basicola . 
(7) The infection of nearly 100 different species of plants with T. 
basicola from tobacco is further evidence that no specialized races of 
this fungus appear to exist.
