List of Australian Ustilagin^, with Description of and 

 Remarks about a New South Australian Species. 



The Ustilaginai, or Smuts, form an important section of fungi 

 (Coniomycetes), inasmuch as many of them prove destructive to 

 grasses and cereals useful or indispensable to man. 



The following is a list of those known from Australia accord- 

 ing to Dr. F. Ludwig, which is remarkable for its paucity. Of 

 the 400 species known, 86 occur in Germany alone, hence the 

 above-named specialist directs the attention of Australians to 

 this section as otlering a wide field of discovery. I collate Dr. 

 Lud wig's list with Dr. Cooke's from 1880 to show the modifica- 

 tions and additions, distinguishing those of the latter left out 

 from the former by enclosure in brackets, and the additions by 

 an asterisk.
