EDIBLE AND POISONOUS MUSHROOMS OF CANADA
PHOLIOTA ALBOCRENULATA Peck
Figure 351, page 236
PILEUS 1-4 in. broad, fleshy, at first convex or campanulate, becoming
expanded, nonstriate, margin often appendiculate with veil fragments, very
viscid, ochre-brown to tawny or chestnut, decorated with darker appressed
scales which on drying become faded and subsquarrose. flesh moderately
thick, whitish, odor not distinctive, taste unpleasant, lamellae sinuate-adnate
to subdecurrent, broad, close to subdistant, at first grayish, becoming rusty
brown, white-crenulate on the edge, stipe 2-5 in. long, Ys-Yz in. thick, equal or
sHghtly enlarged at the base, often curved, pallid or tinged yellow or brown
below, white-floccose at the apex, sparsely to densely scaly up to the annulus
with squarrose or fibrillose scales, annulus slight, ragged, disappearing, often
clinging in fragments to the pileus margin and failing to form a ring on the
stipe. SPORES smooth, brown, inequilateral, subfusiform, 11-14 X 6-7 /x.
Solitary or in groups of several, on stumps and logs, and on trunks of
living trees, especially maple. June-Sept.
The white-crenulate edge of the lamellae is the most striking single
character of this species. The fruiting bodies are darker colored than those of
P. aurivella and usually are not in clusters. The scales on the pileus are rather
easily rubbed off or washed off. The large spores will also distinguish it readily
from similar species. Its edible quahties are not known.
PHOLIOTA AURIVELLA (Batsch ex Fr.) Kummer Edible
Figures 267, 268, page 175
PILEUS 1 1/2-4 in. broad or sometimes larger, fleshy-pliant, hemispheric to
convex with inrolled margin at first, becorriing expanded, smooth, viscid when
moist, yellow to tawny, darkest on the disk, concentrically spotted with darker
squamules which in age become appressed and sometimes wash off in wet
weather, margin even, somewhat appendiculate. lamellae adnate or sinuate
at the stipe, broad, close, paUid yellowish, then rusty brown, stipe stout, cen-
tral or excentric, 1 1/^-4 in. long, Y^-Yi in. thick, subequal, ^olid or stuffed,
viscid in wet weather, more or less concolorous with the pileus, somewhat
squamulose-scaly below the annulus, often curved, annulus slight, yellowish,
disappearing, spores smooth, eUipsoid, rusty brown, 7-9 X 4-5 y..
Solitary or in clusters on stumps and logs of deciduous trees, fairly common.
Aug.-Oct.
This species is well known in North American literature under the name
of Pholiota adiposa (Fr.) Kummer, but it now appears that the true P. adiposa
is a European species with smaller spores than those of our fungus. P. aurivella
is fairly common and can be recognized by the rather bright colored, scaly,
viscid pileus. The viscid layer should be peeled before cooking.
Collectors on the west coast are likely to confuse this species with P. squar-
roso-adiposa Lange. This latter species occurs in large clusters, often on alder,
