Summary. 



1. Although the Ascigerous stage of Sclerotinia is known 

 in America and Europe, there is no previous record of its 

 occurrence in Australia. 



2. Two apothecia, arising from mummified apricots were 

 found on September 22nd, 1921, near Sydney, New South 

 Wales. 



3. Inoculations of loquats with cultures from the 

 apothecium caused typical brown rot lesions. 



4. The organism is probably Sclerotinia frutigena. 

 Further studies are in progress.
