=B. Rus´selli= Frost—Russell’s Boletus. (Plate CXVIII, fig. 2, p. 436.)
=Pileus= thick, hemispherical or convex, _dry, covered with downy scales
or bundles of red hairs_, yellowish beneath the tomentum, often cracked
in areas. =Flesh= yellowish, unchangeable. =Tubes= subadnate, often
depressed 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
brownish-red_. =Spores= olive-brown, 18–22×8–10µ.
=Pileus= 1.5–4 in. 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
yellow, 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, 18–22µ long, about half as broad.
=Pileus= 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 appearance.
The glabrous viscid pileus and the coloration of the stem distinguish
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 greenish_.
=Stem= long, _attenuated downward_, everywhere covered with a deciduous
reticulated bark two lines high and separating like the bark of birches,
_pale-yellow without and within_.
=Pileus= 1.5 in. broad. =Stem= 5–6 in. long.
Ligneous earth. North Carolina, _Schweinitz_, _Curtis_; Pennsylvania,
_Schweinitz_. _Peck_, Boleti of the U.S.
During several seasons I found B. Betula in Woodland Cemetery,
Philadelphia.
Edible qualities good.
CALO´PODES. _Gr_—beautiful; _Gr_—feet.
=Stem= stout, at first bulbous, typically venose-reticulated with veins.
=Tubes= adnate, their mouths not reddish.
The reticulate stem and adnate tubes of one color distinguish the
species of this tribe. In the Luridi the mouths of the tubes are
differently colored, and in the closely related Edules the tubes are
more or less depressed around the stem or sub-free, and their pores are
commonly stuffed when young. Fries did not admit species with whitish
tubes into this tribe, but we have done so in those cases in which this
was the only character to exclude them.
Tubes yellow or yellowish 1
Tubes white or whitish, at least when young 7
