CLINTON: NORTHS AMERICAN USTILAGINEAE. 505 
Literature. 
It is aimed to include in tlie following references the more important arti¬ 
cles relating to the Ustilagineae. There also have been added such minor arti¬ 
cles as relate to the distribution of the species or especially to the treatment of 
North American species, though the list does not claim completeness in these 
respects. Many additional references are to be found in connection with the 
synonymy of the different species.
