XXII. Synopsis of the Discomycetous Fungi of the 

 United States 



BY M. C. COOKE, M. A. 



The time appears to me to have arrived for making an attempt 

 at obtaining some estimate of the Fungi which have already been 

 detected in the United States, for the purpose of preparing, in some 

 form or other, a guide to the Mycologic Flora. As a preliminary 

 step I have been induced to publish, as speedily as I can prepare 

 them, consecutive lists of groups and sections, sucli as the present, 

 Avhich, hoAvever imperfect it may be, is the best which the materials 

 at my disposal enable me to accomplish. In order to render these 

 lists of real utility in attaining their object, the co-operation of 

 Mycologists in all the States must be earnestly solicited. What I 

 would desire of them is correction and addition, especially of local- 

 ities, and, since many of the species of Schweinitz still require con- 

 firmation, they may be able to furnish this confirmation. All 

 specimens would be acceptable, as helping to a knowledge of the 

 Fungi of the States, and their distribution ; credit being invariably 

 given, either in revised lists, or in the Flora when published, to all 

 who have rendered such aid, their names being inserted, as in the 

 present instance, not only as a guarantee of accuracy, but as a well 

 merited recognition of services rendered. Revisions and additions, 

 as well as specimens, named or unnamed, but localized, are requested 

 to be sent to the address here named.
