directly over the growth of the previous year, and distinct 

 zones of annual growth are thus formed. 



Some members of this family form thin plates of spore- 

 bearing bodies over the surface of logs, or decaying wood, and 

 resemble the other species so slightly that they are frequently 

 not recognized by the inexperienced collector as fungi of the 

 same family. Examples of this manner of growth may be 

 found in Trametcs, and such plants are spoken of as rcsupinate 

 forms, which means that the spore-bearing surface lies upon 

 its back, the pores always pointing outward, then downward. 

 No classification based upon the color of the spores has yet 

 been made, but the divisions depend principally upon the tex- 

 ture of the cap and the arrangement of the pores. 



Dr. W. A. Murrill of the New York Botanical Gardens, 

 Bronx Park, New York City, has done much research work in 

 this group, especially in the genera Polyporus, Foiiics, and 

 Polystictus, and the results of his investigations may be found 

 in the publications of the Torrey Botanical Club. Dr. Murrill 

 very kindly identified specimens collected by Mr. C. C. Han- 

 mer. As the nomenclature adopted in this report is that of 

 Saccardo's " Sylloge Fungorum," the writer considered it 

 better to follow a uniform system, but the nomenclature of 

 Dr. Murrill is appended wherever his determination varies 

 from the Saccardo list.
