EDIBLE AND POISONOUS MUSHROOMS OF CANADA
BOLETINUS PICTUS Peck Edible
Figures 313, 314, page 213
Painted Boletc
PILEUS 1 1/2-4 in. broad, convex, at first dark red, fibrillose, soon becoming
squamulose, the fibrils separating into reddish scales and revealing the yellow-
ish flesh beneath, dry to moist or subviscid, margin somewhat appendiculate
from the veil, flesh yellow, slowly becoming reddish when bruised, tubes
adnate to decurrent, at first yellowish, becoming dingy ochraceous, drying
brown, more or less radiately arranged, stipe 114-3 in. long, )4-!/2 (%) Jri-
thick, equal or swollen at the base, colored Hke the pileus, yellow at the apex,
reddish-scaly below, annulus whitish to grayish, fairly persistent, spores och-
raceous brown, eUipsoid, smooth, (7.5) 8-10 (11) X 3.0-4.0 fi.
July-Oct.
Singly or gregarious in woods or swamps, perhaps associated with pine.
This species is sometimes called the painted boletus and is one of the more
beautiful of our fungi. It is sometimes confused with B. spectabilis but the
latter has gray scales on a red background in contrast to the red scales on a
yellowish background of B. pictus. The spore size will separate them with
certainty.

PILEUS 1 1/2-3 in. or more broad, convex, bright red, at first covered with a
red tomentum, then becoming scaly, the scales viscid, fading to grayish red,
brownish, or yellowish, margin more or less appendiculate. flesh whitish to
pale yellow, becoming brighter yellow when wounded, taste and odor un-
pleasant. TUBES adnate to slightly decurrent, yellowish to ochraceous, drying
dark brown, more or less radiately arranged, stipe 11/2-3 in. long, V^-Vi in.
thick, swollen at the base or nearly equal, yellow above the annulus, red or
yellowish red below, solid, annulus reddish to yellowish, double, more or less
persistent, spores purpHsh brown, ellipsoid, smooth, 11-14 X 4.5-6 /x-
Singly or gregarious, associated with larch in bogs. Aug.-Sept.
The radiating arrangement of the tubes is less marked in this species than
in other Boletinus species. It is a very showy and beautiful species. The grayish
scales and larger spores separate it from B. pictus. B. paluster Peck is somewhat
similarly colored but is smaller and has strongly radiating, decurrent pores,
and smaller spores.
