CLITOCYBE
grayish brown when moist, smooth, glabrous, margin tending to remain in-
curved. FLESH thin, whitish, odor none, taste mild or slightly astringent.
LAMELLAE aduate-decurrent, fairly close, narrow, broadest in the center,
narrowing to each end, whitish to pallid, stipe short, %-l 14 in. long, about
Vg in. thick, sometimes excentric, equal or nearly so, straight or curved, tough,
subfibrillose, pruinose, concolorous with pileus, solid, spores smooth, white,
elUpsoid, 4-5 X 2.5-3 /x.
Solitary or scattered in grass on lawns, etc. Aug.-Oct.
This poisonous little mushroom is dangerous because of its habit of
growing in or near rings of Marasmius oreades, which is often collected for
food. The color of the pileus is somewhat similar in the two species although
the Clitocybe is whiter, but a glance at the lamellae will quickly distinguish
the two.
Clitocybe morbifera Pk. and C. sudorifica Pk. appear to be synonyms of
C. dealbata. C. rivulosa (Ft.) Kummer is a closely related species more pinkish
in color and it is also said to be poisonous.

Figure 160, page 91
PILEUS 1-21/2 in. across, convex becoming expanded, finally plane or
depressed at disk, surface moist, yellow to ochre or brownish ochre, sometimes
with a slight olive cast, covered with very minute gray to dark brown fibrillose
scales which are dense on the disk and more scattered toward the margin,
margin thin, incurved, tomentose. flesh rather thin, firm, yellow, odor and
taste mild, lamellae mostly decurrent with a narrow tooth, sometimes merely
adnate or adnexed, seceding readily, close, moderately broad except for decur-
rent portion on stipe, yellow, often with alternate lamellae short, stipe 1 1/2-
2 1/2 in. long, Ys-Ys in. thick, subequal, yellow, subglabrous to slightly fibrillose-
scaly, becoming hollow, spores smooth, white, broadly oval, 6-7.5 X 4-5 m.
Single, in small clusters of several, or in groups, on decaying coniferous
wood. June-Oct.
The attachment of the lamellae is not typical for the genus Clitocybe, and
the color of the lamellae might lead one to look for it in Flammula. A spore
print should be obtained.
This species is considered to be closely related to Tricholoma rutilans (Fr.)
Kummer, and has been called Tricholoma decorum by Quelet. Singer places
both these species in a new genus, Tricholomopsis.
