EDIBLE AND POISONOUS MUSHROOMS OF CANADA
dryophila and sometimes difficult to distinguish. However, these are all edible
species as well. C. dryophila may be found throughout the growing season and
is sometimes abundant.
COLLYBIA MACULATA (A. & S. ex Fr.) Kummer Edible
Figure 224, page 135
piLEUS 2-6 in. broad, rather firm, convex becoming expanded, disk tending
to remain obtuse, margin at first inrolled, then decurved, becoming somewhat
wavy when fully expanded, surface smooth, glabrous, white, spotted with
rusty brown stains, in age the entire plant becoming rusty-stained, flesh
white, compact, lamellae adnexed to almost free, narrow, crowded, white.
stipe white, IVi-^Vi in. long, up to Yi
in. thick, equal or sHghtly ventricose,
the tapering base extending down some distance into the soil, cartilaginous,
becoming hollow, fibrous-striate to sHghtly grooved, spores broadly oval to
subglobose, smooth, yellowish, 5-7 X 4-5 ii.
In groups or in clusters of 2 or 3, on the ground in woods. June-Sept.
This is a fairly large white species which can be recognized by the rusty
stains that develop as it matures. The spores are not pure white but have a
yellowish tinge. It is reported to be edible but not of particularly good flavor.
COLLYBIA PLATYPHYLLA (Fr.) Kummer Edible
Figure 227, page 135; Figure 416, page 297
PILEUS averaging 21^-5 in. broad, occasionally up to 8 in. broad, convex
to subcampanulate at first, becoming expanded, disk often remaining obtusely
umbonate or sometimes becoming sHghtly depressed, margin at first incurved,
becoming expanded or recurved, in age splitting raggedly, color drab grayish
brown to brownish drab, streaked with darker innate fibrils, paling toward the
margin to grayish white, surface dry or moist, smooth or slightly scurfy.
FLESH thin, white, taste unpleasant, odor mild to unpleasant, lamellae white
or whitish, very broad, subdistant, adnexed, becoming sinuate at the stipe.
STIPE stout, 3-5 in. long or sometimes longer, %-% in. thick, equal or tapering
upward slightly, white or whitish, fibrous-striate, cuticle sHghtly cartilaginous,
center stuff'ed, becoming hollow, spores smooth, white, broadly oval, 7-10 X
5-7 Mj immature spores smaller.
Single or in groups of several, on decaying stumps and logs or in rich soil.
June-Oct.
C. platyphylla is edible but is often infested with insect larvae and the
flavor is said to be strong. The gray color and very broad lamellae are dis-
tinguishing characters.
