EDIBLE AND POISONOUS MUSHROOMS OF CANADA
CLITOCYBE CLAVIPES (Pers. ex Fr.) Kummer Edible
Figure 159, page 91 ; Figure 414, page 296
PILEUS %-2% in. broad, fleshy, convex becoming expanded, often obtusely
umbonate, sometimes centrally depressed, drab grayish brown, smooth
and glabrous, extreme margin tending to remain incurved for some time.
FLESH white, thick at the disk, odor and taste mild, lamellae decurrent, sub-
distant, white or yellowish, broadest in the center, narrowing toward the ends.
STIPE stout, %-2i/2 in. long, 14-% in. thick at the apex, broadening downward
into a clavate-bulbous base i/4-l in. thick, concolorous with the pileus, white
and somewhat spongy within, spores smooth, white, ellipsoid, 6-8 X 3.5-5 /x.
In groups or occasionally in clusters of two or three on the ground in
woods, often under conifers. July-Oct. Fairly common.
The broadly clavate, gray-brown stipe and the subdistant lamellae are the
distinguishing marks of this Clitocybe.
Clitocybe nebularis (Fr.) Kummer is a large cloudy-gray species with
crowded lamellae. It is apparently more common on the west coast than in the
East and collectors in the West are hkely to find it. It may reach 6 inches in
diameter. Kauffman reported it to be edible although he noted that some
European authors had considered it dangerous. There are no collections of
this species from Eastern Canada in the herbarium.
CLITOCYBE CYATHIFORMIS (Bull, ex Fr.) Kummer
PILEUS %-2 in. broad, at first convex, soon umbilicate-depressed to in-
fundibuliform, smoky brown when moist becoming more grayish when dry,
hygrophanous, glabrous or innately fibrillose, margin even, inrolled. flesh
thin, grayish, rather watery, taste mild, lamellae decurrent, narrow, close to
subdistant, grayish brown, stipe 1-2 in. long, V8-!4 in. thick, equal or tapering
upward, brownish or grayish, fibrillose, tomentose at base, spongy-stuff'ed.
SPORES smooth, white, eUiptical-ovate, 7.5-10.5 X 5.0-6.5 ju-
Singly or gregarious on rotten wood. Aug.-Sept.
The gray lamellae are the most striking character of this species, and a
spore print is required to make certain of the color of the spores. Clitopilus
noveboracensis Pk. is somewhat similar in appearance but has pink spores, a
farinaceous odor, and a bitter taste. The spores of C. cyathiformis are amyloid
and Singer has on this account removed it from Clitocybe and placed it in the
genus Cantharellula along with Cantharellus umbonatus and Clitocybe ec-
typoides.
