The chief object of the work is to serve as a field manual. This 



and the succeeding volumes will fill a long felt need of some 



comprehensive work on the more conspicuous fungi of North 



America. 



F. J. Seaver 



Murrill's American Boletes * 



This manual of the Boletaceae contains complete keys to the 

 genera and species and full descriptions of all of the species known 

 in America, The boletes, which are pore-fungi, differ from the 

 polypores chiefly in their fleshy consistency and terrestrial habits. 

 The group contains many of our best edible fungi. On account 

 of their fleshy consistency the plants are altered greatly in drying 

 and it is necessary to keep extensive field notes as an aid in 

 making determinations, A blank form is inserted in the book 

 to serve as a guide to collectors in making field notes. 



The general style and purpose of the book is the same as that of 



"Northern Polypores," which was published at the same time 



and by the same author,

 SIDERED IN Relationship to Natural Photo-synthesis and 

 THE Origin of Life, Proc, Roy, Soc. B, 87: 556-570, 1914, 

 reports obtaining striking, clean cut reactions (by means of 

 Macallum's haematoxylin method) indicating the localization of 

 iron in the stroma of chloroplasts. 



Somewhat earlier Moore and Webster (Proc. Roy. Soc, B. 87: 

 163-176) announced that they obtained a synthesis of formalde- 

 hyde from carbon dioxide and water in the presence of ferric 

 hydroxide and light, Moore concludes that iron salts in the 

 stroma of chloroplasts are primary factors in the initial stages of 

 synthesizing carbon dioxide and water, and also in the production 

 of chlorophyll; the latter in association with the iron-bearing 

 portions of the colorless stroma forming the complete photo-
