EDIBLE AND POISONOUS MUSHROOMS OF CANADA
slightly decurrent, concolorous with pileus. stipe about %-l y^
ii^- long, and
about '/g in. thick, equal or slightly enlarged at the base, fibrillose, concolorous
with pileus or slightly paler, hollow, spores ellipsoid, flattened shghtly on one
side, pale ochraceous in mass, smooth, 7-9 X 4-5.5 \i.
Growing singly or in groups on sticks and debris in the woods. May-Oct.
This is a rather common little brown mushroom with broad lamellae and
a fibrillose pileus, often found early in the spring. T. pellucida (Bull, ex Fr.)
Gill, is similar but has smaller spores, 5.5-7 X 4-5 ju.
CREPIDOTUS
Crepidotus corresponds to Pleurotus of the white-spored group and in-
cludes those species with ochre-brown to rusty spore deposit and in which the
stipe is excentric, lateral, or lacking. The lamellae may be whitish in young
fruiting bodies but become brown as the spores mature. Most of the species
occur on decayed wood and they are mostly rather small and of no importance
as food.

Figure 293, page 195
PILEUS V^-21/2 in. broad, convex becoming expanded, sessile, laterally
attached, often semicircular or kidney-shaped in outline, margin incurved at
first, striatulate when moist, surface coated when young with a dense tawny
tomentum, which, as the pileus expands, becomes separated into tawny, fibril-
lose scales, exposing the paler ground color beneath, flesh thin, pliant, paUid
or tinged yellowish, lamellae radiating from the lateral point of attachment,
moderately broad, close, pallid then dull ochre-brown, edges white, stipe
lacking, the pileus attached to the substrate at a lateral point, spores ovoid,
slightly inequilateral in one profile, dull ochre-brown, 7.5-9 (10) X 5-6 m-
In groups on decaying hardwood, common. May-Oct.
This is one of the larger species of the genus and can be recognized by the
tawny scales on the pileus. C. calolepis (Fr.) Karst. also has a brown tomentum
but has smaller spores. C. dorsalis Peck is reddish yellow and has globose
spores. C. versutus Peck has a white tomentum. C. mollis Peck is glabrous and
somewhat gelatinous, and C. haerens Peck is viscid. C. malachius B. & C. has
globose spores and broad lamellae, and C applanatus (Fr.) Kummer has glo-
bose spores and narrow lamellae. These five species are all white or whitish.
C. cinnabarinus Peck is bright scarlet and more common in the West.
The genus is not important as far as food is concerned but several of the
species are fairly common and will be encountered by the collector.
