AMANITA
This mushroom has been known in North America as A. mappa, but the
correct name is A. citrina. Bruises on the pileus, lamellae, and stipe tend to stain
reddish brown. It has been reported as nonpoisonous but is better avoided.
AMANITA FLAVOCONIA Atk. Possibly poisonous
Figure 123, page 69
PILEUS 1-3 in. broad, convex, expanding to almost plane, sometimes
broadly umbonate, brilliant orange to bright yellow, the entire pileus more or
less unicolorous, usually paling slightly toward the margin, smooth, viscid,
with scattered, very friable, floccose or granular-powdery patches of the bright
yellow volva, soon becoming glabrous, nonstriate on the margin, occasionally
becoming faintly short-striate in places in age. flesh thin except on the disk,
white or tinged yellow next to the pellicle, odor not distinctive, lamellae free
or almost so, white or creamy, often yellow on the edges, close, moderately
broad, stipe 2-5 in. long, V^-Vi in. thick, equal or tapering upward from the
oval to clavate-bulbous base, stuffed, then hollow, white or pale yellow,
pruinose above the annulus, minutely scurfy below, usually with a few friable,
yellow, volval fragments clinging to it. annulus membranous, creamy to
yellow. VOLVA entirely bright yellow, very friable, floccose to granular-powdery
present on the pileus in scattered friable warts, a few fragments usually clinging
to the stipe but most remaining in the soil when the fruit body is collected.
spores smooth, white, ovoid, amyloid, 7-9 (10) X (4.5) 5-6 (7) m-
Fairly common at least in Eastern Canada, scattered or in groups on the
ground in woods. June-Sept.
The two orange-yellow species most hkely to be confused with this one,
A. muscaria and A. frostiana, are both conspicuously striate, and both have
nonamyloid spores. A. flavoconia has much more brilhant coloring than
A.flavorubescens and the base of the stipe does not stain reddish.

PILEUS fleshy, 1 1/^-4 in. broad, convex to campanulate or broadly gibbous,
expanding, hght yellow to deep, dull yellow, or tinged olive-yellow, often dingy
yellow-brown to umber on the disk, bruising brown to reddish brown, smooth,
slightly viscid, decorated with small, very floccose warts which vary in color
from brilhant ochre-yellow to dingy buff", nonstriate, or in places faintly striate
on the margin, flesh thin except on the disk, white or tinged yellow, bruising
reddish, lamellae moderately broad to rather narrow, free or attached by a
line, close, creamy white, stipe 2-55/2 in. long, y^-\ in. thick, equal or tapering
upward, sHghtly swollen at the base to form an oval-clavate bulb, occasionally
tapering below the bulb, stuffed or hollow, white or tinged yellow above,
staining reddish toward the base, pruinose or minutely floccose, sometimes
bearing a few bright yellow volval fragments, annulus membranous, fragile,
