Polyporaceae 



areas. Flesh yellowish, unchangeable. Tubes subadnate, often de- Boletus, 

 pressed around the stem, rather large, dingy-yellow or yellowish-green. 

 Stem very long, equal or tapering upward, roughened by the lacerated 

 margins of the reticular depressions, red or brownisli-red. Spores olive- 

 brown, 1822x8 i o/u,. 



PileilS 1.5-4 m - broad. Stem 3-7 in. long, 3-6 lines thick. 



This is distinguished from the other species by the dry squamulose 

 pileus and the color of the stem. The latter is sometimes curved at the 

 base. Peck, Boleti of the U.S. 



B. Russelli occurs in the West Virginia mountains, where I found 

 and ate it in August, 1883. Though solitary in its method of growth, 

 it is frequent in many parts of Pennsylvania, among leaves in mixed 

 woods. August to October. 



Taste when raw, sweet, mild. Cooked it is rather soft, tasty. Tubes 

 and stem should be removed. 



B. Mor'gani Pk. Pileus convex, soft, glabrous viscid, red or yel- 

 low, or red fading to yellow on the margin. Flesh whitish tinged with 

 red and yellow, unchangeable. Tubes convex, depressed around the 

 stem, rather long and large, bright-yellow becoming greenish-yellow. 

 Stem elongated, tapering upward, pitted with long, narrow depressions, 

 yellow, red in the depressions, colored within like the flesh of the pileus. 

 Spores olive-brown, 18-22/1. long, about half as broad. 



PileilS 1.5-2.5 in. broad. Stem 3-5 in. long, 3-6 lines thick. 



Rocky hillsides in woods of deciduous trees. Kentucky, Morgan. 



In wet weather the anastomosing ridges of the stem swell and become 

 broadly winged, thereby giving the stem a peculiar lacerated appear- 

 ance. The glabrous viscid pileus and the coloration of the stem distin- 

 guish the species. Peck, Boleti of the U. S. 



B. Morgani is found in like localities with B. Russelli. Excepting in 

 its smooth, viscid cap and whitish flesh, it closely resembles the latter. 

 The ridges in the stems of both species swell when moist. 



Its edible qualities are the same as B. Russelli. 



B. Be'tula Schw. birch. Pileus convex, viscose and shining in wet 

 weather, tessellately cracked and reticulated, orange-fawn color, rather 

 small. Flesh yellowish-white. Tubes separating, rather large, yellow, 

 almost like those of B. subtomentosus but not greenisli. Stem long,
