Polyporaceae 



Thin woods and shaded banks. New York, Peck; New England, Boletus. 

 Frost. 



This species is remarkable for the rich yellow color of the tubes, 

 which is retained unchanged in the dried specimens, and for the viscid 

 stem. This character, however, is not noticeable in dry weather and 

 was overlooked in the original specimens. 



Boletus glutinipes Frost Ms. is not distinct. Peck, Boleti of the U. S. 



Hopkins' Woods, Haddonfield, N. J. Grassy oak woods. 1891- 

 1894. Mcllvaine. 



The caps are delicious. 



B. innix'us Frost. PileilS convex or nearly plane, glabrous, yellow- 

 ish-brown, slightly cracked in areas when old, yellow in the interstices. 

 Flesh white. Tubes adnate, lemon-yellow, unchangeable. Stem slen- 

 der, short, much thickened at the base in large specimens, yellowish, 

 streaked with brown, brownish within. Spores iox5/x. 



Grassy woods. New England. Frost. 



The whole plant often reclines as if for support, Peck, Boleti of the 

 U. S. 



B. parasi'ticilS Bull. a parasite. PileilS convex or nearly plane, dry, 

 silky, becoming glabrous, soon tessellately cracked, grayish or dingy- 

 yellow. Tubes decurrent, medium size, golden yellow. Stem equal, 

 rigid, incurved, yellow without and within. Spores oblong-fusiform, 

 pale-brown, 12.5-15x41".. 



Pileus 1-2 in. broad. Stem 1-2 in. long, 2-4 lines thick. 



Parasitic on species of Scleroderma. New York, Gerard; New Eng- 

 land, Sprague, Bennett. 



This species is very rare in this country. It is remarkable for its 

 peculiar habitat. Peck, Boleti of the U.S. 



New York, Lydia M . Pate hen; Westfield, on Scleroderma vulgare. 



I found many specimens of this rare species during August, 1897, 

 growing on Scleroderma vulgare. 



Professor Peck, to whom I sent specimens, identified them as B. par- 

 asiticus. The tubes were large, unequal, dissepiments thin, decurrent. 

 The Sclerodermas frequently appear to be parasitic upon the Boletus. 

 I have seen the host plant thrown entirely free from the ground by the 

 Boletus.
