REPORT OF THE BOTANIST. 129 
stipe equal, stout, solid, annulate, subconcolorous, sometimes 
stained with yellow, slightly reticulated at the top; annulus 
and flesh yellow; plant sometimes czespitose. 
Height 4’-6’, breadth of pileus 3-5’, stipe 6-9’ thick. 
Low woods. North Elba. August. <A noble species. 
Large specimens sometimes have a submarginal groove or 
concavity on the pileus. Dedicated to Hon. G. W. Clinton, 
than whom there is no more ardent lover of botany nor more 
devoted friend of science. (Plate 5, figs. 1—5.) 
. BoLETUS ELBENSIS 7. sp. 
Pileus convex, sometimes gibbous, smooth, viscid when 
moist, dingy-gray tinged with flesh-color, obscurely streaked 
and reticulated with darker hues ; tubes nearly plane, attached, 
subdecurrent, rather large, angular, compound, whitish, 
becoming ochraceous-brown; stipe equal, solid, annulate, 
concolorous below, white above the annulus, the top slightly 
marked by the decurrent walls of the tubes; flesh white. 
Height 4-5’, breadth of pileus 2’—-4’, stipe 4-6” thick. 
Low ground in woods and their borders. North Elba. 
August. 
Related to B. laricinus, but our plant is not at all squa- 
mose, nor does it have the stem pitted. The pileus, from its 
markings, sometimes has the appearance of being pitted or 
slightly eaten on its surface by insects. 
BOLETUS FLAVIDUS /7. 
Pileus convex or expanded, viscid when moist, smooth, 
yellow ; tubes plane or slightly convex, attached, rather large, 
angular, compound, honey-yellow ; stipe rather slender, nearly 
equal, solid, dotted, not annulate, yellow or brownish ; flesh 
whitish, inclining to yellow. 
Height 2-3’, breadth of pileus 2’, stipe 2’-4”’. 
Woods and open places. Common. August-—October. 
Sometimes the pileus is dotted and streaked with red. The 
veil is very fugacious, so that the stipe is seldom found with 
an annulus. Sometimes drops of juice or moisture are seen 
on the tubes and stipe. These turn black with age. The 
fingers are stained in handling the plant. Edible. 
7. BoLEeTus coLLiInitus Scheff. 
Pileus convex, viscid when moist, grayish-white, more or 
less tinged with rusty-red or yellow; tubes plane, attached, 
not large, some of them, at least, divided, whitish, becoming 
yellow ; stipe equal, solid, firm, not annulate, whitish, dotted 
with reddish-brown ; flesh white.
