EDIBLE AND POISONOUS MUSHROOMS OF CANADA
about J/g in. thick, equal, hollow within, fragile, spHtting readily, glabrous,
moist, clear yellow, paler than the pileus. spores smooth, subglobose, 5.5-
6.5 X 5-6 M, pinkish in deposits, cystidia slightly ventricose, with an elon-
gated neck, obtuse at the apex, not horned.
In groups or scattered, on badly decayed logs and stumps, fairly common.
June-Sept.
This is one of the more common of the smaller species and is an attractive
little mushroom. One of the most distinctive field characters is the yellow
stipe. P. flavofuligineus Atk. is another small yellow species with a pinkish
stipe, and P. leoninus (Fr.) Kummer has a white stipe and the pileus is not
wrinkled. These species are all too small to be of value as food.
PLUTEUS ATROMARGINATUS (Sing.) Kuhner Edible
Figures 242, 243, page 153
PILEUS \-2y2 in. broad, convex to expanded-convex, sometimes broadly
umbonate or subumbonate, dark brown, moist, somewhat uneven, more or
less fibrillose-streaked, the disk squarrose-scaly with minute upright tufts of
fibrils, margin not striate, flesh moderately thick on the disk, very thin on the
margin, white, odor and taste mild, lamellae free and not quite reaching the
stipe, close to crowded, moderately broad, whitish, then dingy flesh color with
smoky brown edges, many shorter lamellae of various lengths interspersed.
stipe 1-3 in. long, V8-!4 ii^- thick, subequal or sHghtly enlarged at the apex or
base, whitish or tinged the color of the pileus, solid within, glabrous at the
apex, fibrillose with smoky brown fibrils below, spores smooth, broadly ovoid,
5.5-7 X 4.5-5.5 /x» dingy flesh color in spore print, cystidia fusoid-ventricose,
horned at the apex.
Solitary or scattered on decaying logs and stumps, not common. July-
Oct.
The dark edges of the lamellae which provide a good field character for
this species, are caused by the dark contents of the cystidia. This species is
usually smaller and darker colored than P. cervinus and has been called P.
umbrosus (Pers. ex Fr.) Kummer, but the latter has cystidia of a diff'erent type.
PLUTEUS CERVINUS (Schaeff*. ex Seer.) Kummer Edible
Figures 245, 246, page 155
PILEUS 1 1/^-4 in. broad, fleshy, soft, at first convex to broadly campanu-
late, expanding to almost plane, the broad umbo either persisting or disap-
pearing, smooth and glabrous to somewhat fibrillose, moist to dry, drab,
varying from dull dark brown to pale dingy fawn (white in var. albus), darkest
on the disk, paler toward the margin, sometimes streaked with darker innate
fibrils, fading with age, margin even, flesh very thin on the margin, thicker
