Polyporaceas 



Pine woods and open sedgy places. New England, Frost. Boletus. 



Specimens not seen. The species seems too near B. bovinus, of 

 which it may possibly be a variety, but its yellow flesh and the colors 

 ascribed to the tubes and spores require its separation. Rev. C. J. 

 Curtis sends notes of a species found by him in North Carolina, which 

 agree with this in its characters so far as noted. Peck, Boleti of the U.S. 



B. ignora'tus Pk. PileuS convex, viscid, bright lemon-color, marked 

 with wrinkled lines of orange color, which are distributed over the pi- 

 leus, giving it a streaked appearance. Flesh white, solid, does not 

 change color when cut or broken; taste slightly acid. Pores lemon- 

 color, moderately large, free, connected with the stem by web-like fila- 

 ments. Stem larger at the apex, somewhat tapering toward the base, 

 yellow, smooth, solid. Spores 4.5xn/>t. 



This closely approaches Boletus unicolor Fr., from which it scarcely 

 differs except in its white flesh and free tubes. Fungi of Maryland, 

 Mary E. Banning. Peck, 44th Rep. N. Y. State Bot. 



B. bovi'nus bos, an ox. PileuS nearly plane, glabrous, viscid, pale 

 yellow. Flesh white. Tubes very short, subdecurrent, their mouths 

 compound, pale yellow or grayish, becoming rust-colored. Stem equal, 

 even, colored like the pileus. Spores fusiform, dingy greenish-ocher, 

 7.5-10x3-4,*. 



Pileus 2-3 in. broad. Stem 1.5-2 in. long, sometimes cespitose. 



Pine woods. North Carolina, Schweinitz, Curtis; Pennsylvania, 

 Schweinitz; New England, Frost, Palmer, Bennett, Sprague, Farlow; 

 California, H ' . and M . 



The shallow tubes, 2-3 lines long, are said to resemble the pores of 

 Merulius lacrymans. The species is recorded edible by Curtis, Gillet 

 and Palmer. Peck, Boleti of the U. S. 



West Virginia mountains under hemlocks, 1882-1885, and near Had- 

 donfield, N. J., under pines. Mcllvaine, 1892. Gregarious and in 

 clusters. The pore surface was in some specimens broadly wrinkled. 



Smell and taste pleasant. Cooked, the quality is of the best in Boleti. 



B. rubinel'lus Pk. dim. of ruber, red. Pileus broadly conical or 

 convex, viscid when moist, subtomentose or slightly pubescent when 

 dry, red fading to yellow on the margin. Flesh whitish or yellowish,
