The decay of quince fruit caused by Sclerotinia cinerea is distributed generally over the globe. A closely related species of fungus (S. fructigena) very frequently attacks apples and pears as well as quinces in Europe. Considerably less damage is done to the quince than to apples and pears. It is also less destructive in America than in Europe on any of the three above-named fruits. Sometimes S. fructigena attacks stone-fruits in Europe; however, the Brown Rot of stone-fruits and pome-fruits in America is due chiefly or entirely to S. cinerea. The characters of Brown Rot on quinces are not notably different from those described for peaches, to which the reader is referred (page 270). Special control measures do not seem necessary, at least in America.
