EDIBLE AND POISONOUS MUSHROOMS OF CANADA
ering of both pileus and stipe. It is somewhat shiny when dry. It is usually
larger than H. borealis Pk. and H. niveus Fr.
HYGROPHORUS FLAVESCENS (Kauffman) Smith & Hesler Edible
Figure 195, page 113
PILEUS brittle-fragile, %-2'4 in. broad, convex to expanded-convex with
decurved margin, often shghtly irregular in outhne, striate on the margin when
moist, smooth, glabrous, viscid, shining when dry, at first bright orange, fading
in streaks to bright yellow, then paler yellow, flesh thin, pale yellowish, odor
and taste not distinctive, lamellae unevenly attached, mostly adnexed, varying
from broad to moderately narrow, close to subdistant, thick and waxy, deep
yellow to pale lemon-yellow, many shorter lamellulae present, trama of
parallel hyphae. stipe 1 J4-3 in. long, Y^-Yi in. thick, subequal or tapering
downward, often compressed or grooved, hollow, waxy to the touch but not
viscid, orange to yellow, usually paler than the pileus, whitish at the base.
SPORES smooth, white, ellipsoid, 7-8 X 3.5-4.5 /x.
In groups or scattered, on the ground in woods, fairly common. June-
Sept.
Kauffman described this fungus as a variety of H. puniceus but it is evi-
dently a distinct species. H. chlorophanus Fr. is similar but has a viscid stipe.
The stipe of H. flavescens may feel sHppery or subviscid on handling but it is
not truly viscid. H. chlorophanus is apparently rare but H. flavescens is common
and probably most specimens identified as H. chlorophanus are, in reality,
H. flavescens.
HYGROPHORUS MARGINATUS Pk. Not recommended
Figure 196, page 113
PILEUS 1/2-2 in. broad, at first obtusely conic with incurved margin,
becoming more or less convex to broadly expanded, disk often tending to
remain obtuse, smooth, glabrous, moist, hygrophanous, bright orange, fading
gradually to pale yellowish, flesh thin, fragile, concolorous with pileus, odor
and taste not distinctive, lamellae adnexed, broad, ventricose, subdistant,
intervenose, bright orange, retaining this deep color, especially on the edges,
after the rest of the plant has faded, trama of subparallel to interwoven hyphae.
STIPE 1-3 in. long, up to 54 in. thick, subequal, often slightly compressed,
hollow, smooth, glabrous, moist, concolorous with pileus or paler, spores
smooth, white, oval, apiculate, 7-9 X 4-6 /x.
In groups on ground in woods. Not common. July-Sept.
The most striking character of this species is the manner in which the
lamellae retain their colors after the pileus has faded. Sometimes the edges of
the lamellae are brighter colored but not always. Kauffman reported this
species as suspected and we have no further information about it, hence it is
not recommended for food.
