Sclerotina fructigena is the only form to which he gives a 

 specific name. In hie summary horevor he says in part: 



"The causal organism is a grey Monilia. easily distinguished 

 from &[. fructigena; at present it is to be referred to konilia cine^ea 

 Bon. 



On culture media the habit of the fungus is different from that 

 of the grey Monilia (also referred to ]. cinerea by American vorkert) 

 which is coomonly found in North America," 

 b. In the United States 



Smith (9) in 1889 states that Mpniliu fructigena causes a destructive 

 rot of peach fruit and blight of young p^ech branches in the orchards of 

 Delaware and Maryland. He says, 



"In the fungus the corranon node of propagation from peach to peach, and 

 the only knom one, is by aeant of ash-gray ccnidis, which are pro- 

 duced in greet numbers on ih brown surface of the effected parts* 

 These spores generally occur in little hemispherical tufts or confluent 

 masses on bundle* of hyphcd threads which have burst through the skin 

 of the peach. 1 * 



Smith si>ys that he firet discovered the blight in the summer of 

 1887 in Delaware* Ha also says that this fungus occurs destructively on 



peaches, apricots, plums and cherries, and to scot extent kltso on apples, 





 pears , and quinces. 



Cordiey (10) in 1899 gives the name Monilia fructJEena to the form 

 occurring on prunes, cherries, peaches, apples, pears and quinces in Oregon. 

 As to color ho says: 



"In passing through almost any of our prune orchards when the green 

 fruit is being picked, or even earlier, one cauy see here and there a
