TRICHOLOMA
TRICHOLOMA SEJUNCTUM (Sow. ex Fr.) Quel. Edible
Figure 183, page 111
PILEUS 1 14-3 in. broad, fleshy, convex becoming expanded, umbonate,
often somewhat irregular in outline, smooth, slightly viscid, white to yellowish,
streaked with minute, radiating, innate, blackish fibrils, in dark specimens with
the entire disk umber-brown to blackish, flesh white or tinged yellow, taste
bitter to nauseous, lamellae broad, white, adnate, becoming notched at the
stipe, close to moderately distant, stipe stout, 2-4 in. long, 54-/4 ^^' thick,
more or less equal, often curved, usually solid, smooth, white to straw-colored.
SPORES smooth, white, broadly ovoid, 6-7 X 4-5.5 m-
In groups, on the ground in woods. Sept.-Oct.
T. sejunctum diff'ers from T. flavovirens in its fibrous-streaked pileus and
white lamellae. Specimens with a more or less yellow tinge in the lamellae
have been found and these might be T. intermedium Peck but they were growing
along with typical forms of T. sejunctum and it seems more likely that this
yellow color in the lamellae represents a variation rather than a distinct species.
TRICHOLOMA SUBACUTUM Pk. Doubtful
Figure 233, page 136
PILEUS 1 1/4-3 in. broad, at first conic-campanulate with incurved margin,
expanding to broadly convex with a conspicuous acute umbo, varying in color
from slate-gray or pale gray to ashy or grayish brown, sometimes blackish on
the umbo, fading toward the margin, streaked with minute, radiating, dark
fibrils, dry, glabrous or slightly fibrillose-scaly. flesh thin except at the umbo,
white, odor not distinctive, taste somewhat acrid, lamellae adnexed, close,
broad, white, stipe 2-4 in. long, y^-Vi in. thick, equal, smooth or slightly
fibrillose-scaly, solid, white, spores smooth, white, broadly ovoid, 6-7.5 X
4.5-5 M.
In groups, on the ground in conifer woods. Sept.-Oct.
Apparently there are several closely related forms similar to T. subacutum.
There is some disagreement as to their edibility but none are known to be
dangerously poisonous. The gray color and prominent, acute umbo are the
most distinctive characters. T. virgatum (Fr.) Kummer is probably the same
fungus and, if so, this would be the correct name for it.
TRICHOLOMA TERREUM (Schaeff. ex Fr.) Kummer Edible
Figure 185, page 111
pileus 1-21/2 in. broad, convex to expanded, subumbonate, gray or
mouse-colored, dry, fibrillose, becoming fibrillose-scaly to slightly floccose,
with the scales concolorous or dark gray to sooty, flesh thin, fragile, white,
grayish beneath the cuticle, odor and taste mild, lamellae adnexed, close,
moderately broad, white to dingy, stipe short, 1-2 in. long, I/8-I/4 in. thick,
