It has also been known under the names Boletus clintonianus Peck and B. ele-
gans Fr. The shmy cuticle should be removed before cooking.
SUILLUS PIPERATUS (Bull, ex Fr.) Kuntze Not edible
Figure 335, page 233
piLEUS %-2i4 in. broad, convex, yellowish brown, cinnamon-brown or
reddish brown, glabrous or subtomentose toward the margin when young,
slightly viscid when moist, flesh whitish or yellowish, sometimes tinged red-
dish, sometimes turning blue near the tubes when wounded, the blue quickly
fading again, taste very acrid and peppery, tubes adnate to shghtly decurrent,
deep reddish brown, irregular, slightly radially arranged near the stipe, stipe
1-3 in. long, J/g-^/i ii^- thick, equal or nearly so, straight or curved, paler than
the pileus, bright yellow at the base, soHd. spores rusty brown, elUpsoid,
smooth, 8-11 X 3-4 /z.
On the ground in woods and open places. July-Oct.
The most distinctive character of this small brownish species is the very
peppery taste. S. rubinellus (Peck) Sing, is another small species but brighter
colored, with tubes entirely red and mild taste.
SUILLUS SUBLUTEUS (Peck) Snell Edible
Figure 336, page 233
PILEUS 1-3 in. broad, convex to nearly plane, yellowish brown to reddish
brown, sometimes with an olive tinge, viscid, glabrous or somewhat virgate-
fibrillose to indistinctly squamulose. flesh yellow or yellowish, unchanging,
mild or sHghtly acid, tubes adnate, yellow at first, becoming more olivaceous
in age, glandular-dotted, stipe lYz-^Vi in. long, |4-!^ in. thick, equal above
and below the annulus, yellow above, more pallid toward the base, solid.
ANNULUS forming an apical to median, grayish band, not sheathing the stipe,
viscid. SPORES brownish-ochraceous, ellipsoid, smooth, (7.5) 8-10 (11) X 2.5-
3.5 fjL.

It is likely to be confused with S. luteus (L. ex Fr.) S. F. Gray which is
generally a stouter plant with a stipe usually more than Yi in. thick, and the
annulus forming a sheath rather than a band on the stipe. S. luteus is more
likely to be found associated with two-needle pines.
