Art. XXXI. — Contributions to the Mycology of North America ; 

 by the Rev. M. J. Berkeley, of England, and the Rev. M. A. 

 Curtis, of South Carolina. 



Mr. Berkeley having generously proposed that the new species 

 of Fungi which I communicate to him shall be published under 

 our joint names, though the greater part of them would justly 

 have fallen to his own share, they will henceforth be published 

 accordingly. They will be first described in the London Journal 

 of Botany by Mr. Berkeley, and transferred from thence to this 

 Journal, with such alterations, additions or omissions, as later ob- 



pu rpose 



these contributions. — M. A. C.
