In the study of the above species and compilation of the 
descriptions I have had the assistance of many mycologists to 
whom cordial thanks are hereby extended. To those to whom 
in addition special obligations are acknowledged are Messrs. J. 
B. Ellis, and J. C. Arthur. 
This fascicle completes a century of specimens and those 
purchasing, rather than exchanging for the same, are notified that 
the price ($5.00) is now due. 
The issue of specimens will be continued at intervals, perhaps 
four or five fascicles appearing in the course of the next twelve 
months.

“Serait-ce encore une des varieties de l’U. blanc? II en differe 
parce qu’il ne croit qu’a la surface superieure des feuilles que ses pustules 
sont plus regulierement arrondies, et s’ouvrent d’elles-memes a la fin de 
leur vie, pour donn'er issue a la poussiere.” De Candolle, Flore Fran- 
caise, 6:88. 1815.
