EDIBLE AND POISONOUS MUSHROOMS OF CANADA
pellicle separable, margin tuberculate-striate. flesh white, not red under the
pellicle, thin, fragile, very acrid, lamellae adnexed, close to crowded, ventri-
cose, white, stipe 1-2 in. long, Ya-Yz in. thick, equal, smooth, white, spongystuffed
to hollow, fragile, spores white, subglobose, 7-9 X 6-8 m, ornamented
with moderately high warts, more or less joined by lines and ridges to form a
partial reticulum.
Scattered on the ground in woods. July-Sept. Common.
See the notes on R. emetica for a comparison with this species.
RUSSULA INTEGRA (L. ex Vitt.) Fr. Edible
Figure 109, page 51
pileus 2-5 in. broad, at first firm, soon becoming fragile, convex becoming
plane or sHghtly depressed, color variable, rather dingy or sordid, from buff
to reddish brown to dark, dull red, fading, glabrous, viscid when wet, pellicle
separable, margin becoming coarsely tuberculate-striate. flesh white, mild.
lamellae adnexed, nearly free, distant, broad, white becoming pale yellow.
stipe 1V2-2J4 ill- long, Vz-^
^^- thick, tapering upward to nearly equal,
sometimes ventricose, smooth, white, spongy-stuffed, fragile, spores pale
yellow, subglobose, 7-9 X 5.5-7 /x, ornamented with low to medium separate
warts, some more or less confluent or joined by fine lines.
Gregarious on the ground in woods. Aug.-Sept.
The exact identity of R. Integra appears to be somewhat in doubt but this
is believed to be the same fungus that was described by Kauffman under this
name. It is a medium-sized, dull red species and has a pale yellow spore
deposit and mild taste. The stipe is never red.
RUSSULA LUTEA (Huds. ex Fr.) S. F. Gray Edible
Figure 101, page 49
PILEUS 1-21/2 in. broad, thin, fragile, plane or shghtly depressed, bright
yellow to golden yellow, glabrous, viscid, pellicle separable, margin even,
becoming slightly striate when old. flesh white, thin, fragile, mild, lamellae
free, subdistant, rather narrow, broader at the front, bright ochraceous.
STIPE 1-2 in. long, about 14-/4 in. thick, equal or slightly tapering upward,
smooth, white, spongy-stuffed becoming hollow, spores ochraceous, globose,
8.5-10 X 7.5-9 /x, ornamented with moderately coarse warts, mostly separate
or some confluent forming short ridges.
Usually solitary on the ground in mixed woods. Aug.-Sept.
This species is fairly easily recognized with its bright yellow pileus and
deep ochraceous lamellae and spores.
