PREFATORY 



THE first edition of "One Thousand American Fungi" so fully 

 embodied the species known to be edible, that the field for fresh inves- 

 tigation has been confined principally to newly discovered species. In 

 the eighteen months elapsing since the publication of the first edition, 

 Professor Charles H. Peck the American authority upon fungi has 

 reported several. These, with his descriptions, are named in the sup- 

 plement. 



The many requests made of the author for information upon the 

 raising of mushrooms show a prevalent interest in the industry. What 

 he knows is stated herein; what he does not know, and what is not 

 known upon the subject, would furnish the matter for a volume. 



Interest in the study of fungi is well established and is rapidly in- 

 creasing. This department of botany has been made a specialty in 

 many colleges and schools. Its importance is everywhere recognized. 



The author and publishers feel a just pride in the success of "One 

 Thousand American Fungi." The prompt sale of the first edition, and 

 immediate demand for the second, warrant it. Their thanks are due to 

 the many who have kindly interested themselves in obtaining subscrip- 

 tions to the author's edition.
