REPORT OF THE BOTANIST. 33 
stem firm, thickened at the base, glandular-dotted, exannulate, solid, rhu- 
barb-yellow; spores .00035'— 0004 long, .00016’ broad, flesh yellowish, inclin- 
ing to grayish in the stem. 
Plant 2/4’ high, pileus 2/—3’ broad, stem 3 /—65’' thick. 
Ground in woods. Gansevoort. Aug. 
This species belongs to the section Viscipelles. It is related to such species 
as B. albus, B. granulatus, ete. Its rhubarb-colored stem thickened at the 
base and the brownish color of the young hymenium are its distinguishing 
features. 
BoLetus RUBINELLES x. sp. (Plate II, figs. 18-20.) 
Pileus at first broadly conical or subconvex, then expanded, subtomentose, 
red, becoming paler with age; tubes convex, adnate or somewhat depressed 
around the stem, rather large, subrotund, pinkish-red, then sordid-yellow; 
stem equal, smooth, yellow with reddish stains; spores oblong, .0005’-.0006' 
long, .00016’ broad ; flesh of both pileus and stem bright-yellow. 
Plant about 2’ high, pileus 1/—2! broad, stem 1 ‘-2’ thick. 
Ground in woods. Gansevoort. Aug. 
The species belongs to the section Subtomentosi, and is apparently related 
to B. rubinus. 
BoLeTUSs SENSIBILIS 7. sp. 
Pileus at first firm, convex, pruinose-tomentose, brick-red, then expanded, 
paler or ochraceous-red, glabrous, soft ; tubes at first plane or concave, bright- 
yellow, then tinged with green, finally sordid-yellow, small, subrotund; stem 
firm, smooth, lemon-yellow, narrowed at the top when young, and sometimes 
slightly cribrose from the decurrent walls of the tubes, often stained with red 
or rhubarb-color; spores greenish-brown, .0005’' long, .00016' broad; flesh 
of the pileus pale-yellow, of the stem brighter colored and marbled, both fiesh 
and tubes quickly changing to blue when wounded. 
eae scattered or ceespitose, 4/-6' high, pileus 5’—8! broad, stem 6 /-12! 
thick. 
Ground in woods. Gansevoort. Aug. 
The species belongs to the section Subpruinosi. The specific name is sug- 
gested by the ease and rapidity with which the change of color is produced. 
Merely handling the specimens produces the blue color where they are pressed 
by the fingers. The species seems near B. miniato-olivaceus, but the differ- 
ence in the color.of the pileus and in the character of the stem and its sus- 
ceptibility to change of color seem to require its separation.

Ground in woods. Sandlake. Aug. 
The margin of the pileus in our specimens is conspicuously involute when 
young. The stem is sometimes yellow at the top. The species belongs to 
the section Edules.
