EDIBLE AND POISONOUS MUSHROOMS OF CANADA
COPRINUS MICACEUS (Bull, ex Fr.) Fr. Edible
Figure 305, page 213
Glistening Inky Cap
PILEUS 1/2-2 in. broad, at first ovate to elliptical, becoming conic to cam-
panulate, ochraceous tan to ochraceous brown, sometimes fading to whitish,
usually darker on the disk, at first covered with minute, ghstening particles
which may either persist or disappear in older specimens, strongly striate to
sulcate, the striae of unequal lengths, smooth on the disk, more or less lobed
and uneven on the margin, lamellae adnate-seceding, crowded, moderately
broad, at first white, then purpHsh to black and dissolving into an inky fluid.
STIPE 1-3 in. long, Vg-W in. thick, equal, silky,
brown to black, eUipsoid to ovoid, 7-9 X 4-5 n.
white, hollow, spores dark
Usually in dense clusters on the ground or around old stumps. Very
common and may be found throughout the growing season.
This species is rather small and dehcate, but usually appears in consider-
able abundance. Many householders regard it as a nuisance because they
consider the masses of fruiting bodies appearing on the lawn to be unsightly.
It is associated with buried wood and may continue to appear for several
years in places where a tree has been removed and old roots remain in the soil.
Successive crops of fruit bodies may develop throughout the growing season
following wet periods.
COPRINUS QUADRIFIDUS Peck Edible
Figure 302, Page 195
PILEUS 1-3 in. broad, at first oval, becoming campanulate to somewhat
expanded, gray to grayish brown, at first covered with a tomentose-floccose
veil which breaks up into flakes or scales and may disappear, margin long-
striate, often wavy, becoming rolled back, lamellae free, crowded, broad, at
first whitish, then dark purple-brown to black, stipe 1 J4-4 in. long, Ys-Vs in-
thick, equal or tapering upward, white, somewhat floccose, with an evanescent
basal annulus. spores black, smooth, elHpsoid, 7.5-10 X 4-5 /x.
Gregarious or cespitose on rotten wood. June-Aug.
This is a good edible species often appearing early in the season and
occurring on rotten wood. It diff'ers from C. atramentarius in having floccose
veil patches on the pileus and in its occurrence on rotten wood. The fruit bodies
arise from well-developed, root-like strings of mycehum termed rhizomorphs.
