BOLETACEAE<br />
cose, evanescent, spores cinnamon-brown, ellipsoid, smooth, (8) 9-10 (11) X<br />
3-4 (5) M<br />
Gregarious on the ground in woods or open places, probably associated<br />
with pine. July-Sept.<br />
This species is easily confused with S. subaureus (Pk.) Snell. The latter has<br />
a thicker stipe, less heavily glandular-dotted, and a thicker pileus. The spores of<br />
S. subaureus are slightly smaller, mostly 7-9 m long and only rarely reaching<br />
10 M> whereas spores of S. americanus are mostly 9-10 ju and some reach 1 1 /x.<br />
It is usually described as lacking an annulus but one collection was found<br />
which agreed with S. americanus in every respect but had a clearly marked<br />
annulus present.<br />
It is said to be edible but lacking flavor.<br />
SUILLUS GRANULATUS (L. ex Fr.) Kuntze Edible<br />
Figure 333, page 233<br />
PILEUS %-3 54 in. broad, convex to plane, usually reddish brown but vari-<br />
able to grayish pink, grayish yellow, tawny, or brown, viscid, glabrous, flesh<br />
pale yellowish to whitish, mild, tubes adnate, yellowish, the mouths glandular-<br />
dotted, stipe %-2% in. long, Ya-Vi in. thick, equal or nearly so, white to<br />
brownish, yellow near apex, glandular-dotted at apex to about half way down,<br />
soHd. spores yellowish brown, elHpsoid, smooth, (6) 7-9 (10) X 2.5-3.5 m-<br />
Usually gregarious in woods or open places, probably associated with<br />
pine. June-Oct.<br />
This is one of our commonest boletes. It is most Hkely to be confused with<br />
S. brevipes (Peck) Kuntze which is also associated with pines but usually<br />
appears late in the year and has a short stipe that lacks glandular dots. Both<br />
species are good to eat.<br />
SUILLUS GREVILLEI (Kl.) Sing. Edible<br />
Figure 334, page 233<br />
PILEUS 1 1/^-4 in. broad, sometimes larger, convex to nearly plane, chest-<br />
nut-brown to yellow on margin, or reddish yellow to golden yellow, glabrous,<br />
viscid, margin sometimes more or less appendiculate. flesh yellow, mild.<br />
TUBES adnate to decurrent, bright golden yellow, becoming brown or purplish<br />
brown when wounded, stipe 1-4 in. long, 54-% in. thick, equal or sHghtly<br />
tapering upward, usually finely reticulate above the annulus, not glandular-<br />
dotted, variable below the annulus, more or less fibrillose to glabrous, reddish<br />
or reddish brown to yellow, bright yellow above the annulus, soHd. annulus<br />
whitish to yellowish to reddish brown, usually prominent and persistent.<br />
spores golden brown to ochraceous brown, smooth, ellipsoid, 7-1 1 X 3-4 m-<br />
Gregarious on the ground, associated with larch. Aug.-Oct.<br />
Sometimes this species is very richly colored and striking in appearance.<br />
