EDIBLE AND POISONOUS MUSHROOMS OF CANADA<br />
CLITOCYBE ODORA (Bull, ex Fr.) Kummer Edible<br />
Figure 168, page 109<br />
PILEUS 1-3 in. broad, convex with margin incurved at first, becoming<br />
expanded, varying in color from bluish green or grayish green to whitish,<br />
tinged green or entirely lacking the green tints, smooth and glabrous, flesh<br />
white, thin toward the margin, odor sweet, fragrant, sometimes faint, lamel-<br />
lae broadly adnate to subdecurrent or short-decurrent, close, moderately<br />
broad, white to creamy yellowish or tinged green, stipe 1-3 in. long, V8-!4 in.<br />
thick, equal or sHghtly thickened at the base, whitish to pallid, concolorous,<br />
pruinose above, white-mycelioid at base, becoming hollow, spores smooth,<br />
white, oval, 6-8 X 4-5 /x.<br />
Solitary or in clusters of 2 or 3, on the ground in woods, often attached to<br />
leaves and debris. July-Oct.<br />
The greenish colors and the fragrant odor of anise are the distinguishing<br />
marks of this species, but the greenish color is sometimes entirely lacking and<br />
the fruiting bodies may then be white. A smaller and thinner species C. fra-<br />
grans (Sow. ex Fr.) Kummer has a similar odor.<br />
LEUCOPAXILLUS<br />
Leucopaxillus is rather difficult to define in such a way that the amateur<br />
collector can readily recognize the genus by the gross appearance, but it is<br />
fairly easy to determine by microscopic characters. It includes Clitocybe-like or<br />
Tricholoma-WkQ species with rough-walled spores that turn blue in iodine.<br />
These species are mostly whitish or dull colored, with fairly large to large pilei<br />
and fleshy stipes. The attachment of the lamellae varies from decurrent to<br />
sinuate. Unless a microscope is available the beginner will have some difficulty<br />
at first in recognizing a Leucopaxillus and will be inclined to look in Clitocybe<br />
or Tricholoma.<br />
Singer & Smith (1943) published a monograph on the genus and recog-<br />
nized twelve species. Some of the species they included in Leucopaxillus were<br />
formerly known as Clitocybe gigantea (Fr.) Quel., Tricholoma laterarium<br />
(Pk.) Sacc, T. tricolor Peck, Clitocybe albissima (Peck) Sacc, and as varieties<br />
of the latter, C. piceina Peck, C. subhirta Peck, and Tricholoma lentum (Post in<br />
Romell) Sacc.<br />
LEUCOPAXILLUS ALBISSIMUS (Pk?) Sing.<br />
var. PICEINUS (Peck) Singer & Smith Edible<br />
Figure 222, page 134<br />
PILEUS 2-4 in. broad, sometimes larger, convex becoming plane or nearly<br />
so, dry, glabrous to slightly fibrillose, especially toward the margin, whitish to<br />
