=A. monticulo´sa= Berk.—mountain, from the warts. =Pileus= 2.5–3 in.

across, convex, areolate, with a wart in the center of each areola;

those toward the margin consisting of soft threads meeting in a point,

but sometimes simply flocculent, the central warts angular, pyramidal,

truncate, discolored. =Stem= bulbous, scaly, flocculent, white. =Veil=

thick, at length distant. =Gills= free, ventricose, remote, forming a

well-defined area around the top of the stem. The warts are not hard and

rigid as in A. nitida, and the free remote gills separate it from that

and the neighboring species. _Berk._

North Carolina, sandy woods, common. _Curtis._

Properties not known.

=A. dau´cipes= B. and M.—_daucum_, a carrot; _pes_, a foot. =Pileus= 2–5

in. broad, hemispherical, globose. =Flesh= white, soft, warts regular,

pyramidal, saffron color. =Gills= narrow, reaching the stem, broadest in

the middle. =Stem= 5–6 in. high, solid, base bulbous, with a restricted

cortina above, squamulose downward. =Veil= fibrillose, extending from

the margin of the pileus to the apex of the stem, fugacious.

In cultivated fields. Ohio. _Sullivant._ Properties not given.

=A. lenticular´is= Lasch.—resembling (the stem) a lentil.

Fries places this species in Amanita, in which Stevenson follows him.

Cooke and Massee place it in Lepiota, where it will be found.

**** _Volva rudimentary, wholly disappearing._

=A. chlorinos´ma= Pk.—smelling like chlorine. (Plate VIII, fig. 1, p.

18.) =Pileus= convex or expanded, warty on the disk, covered on the even

margin with a light powdery, at length evanescent substance, white.

=Gills= white. =Stem= nearly cylindrical, stout, deeply penetrating the

earth. =Spores= broadly elliptical, 7–10µ long. Odor distinct,

chlorine-like.

=Plant= 6–7 in. high. =Pileus= 4–6 in. broad. =Stem= 1–2 in. thick.

_Peck_, Bot. Gaz., Vol. 4.

Burnt ground in woods. August. Closter, N.J., _C.F. Austin_; Alabama,

_U. and E._; West Virginia, _Nuttall_; New Jersey, _Ellis_; Mt. Gretna,

Pa., July, in a cluster of a dozen individuals, and afterward until

frost, strong smelling, warts brownish-white. _McIlvaine._

It is edible and equal to A. strobiliformis.

=A. calyptra´ta= Pk. =Pileus= fleshy, thick, convex or nearly plane,

centrally covered by a large irregular persistent grayish-white fragment

of the volva, glabrous elsewhere, striate on the margin, greenish-yellow

or yellowish-brown tinged with green, the margin often a little paler or

more yellow than the rest. =Lamellæ= close, nearly free, but reaching

the stem and forming slight decurrent lines or striations on it,

yellowish-white tinged with green. =Stem= stout, rather long, equal or

slightly tapering upward, surrounded at the base by the remains of the

ruptured volva, white or yellowish white with a faint greenish tint.

=Spores= broadly elliptic, 10µ long, 6µ broad, usually containing a

single large nucleus.

=Pileus= 10–20 cm. broad. =Stem= 10–15 cm. long, 12–20 mm. thick.

Rich ground in fir woods or their borders. Autumn. Oregon. _Dr. H.

Lane._

This is a large and interesting species, well marked and easily

recognized by its large size, by the greenish tint that pervades the

pileus, lamellæ, annulus and stem, and especially by the large

persistent patch of grayish-white felty material that covers the center

of the pileus and sometimes extends nearly to the margin. This is in

fact the upper part of the ruptured volva that is carried up by the

growing plant, and is very suggestive of the specific name. In the young

state the plant is entirely enveloped in the volva, which then is

similar to a goose egg in size and shape, and its walls are one-fourth

to one-half inch thick. So thick and firm are they that the young plant

appears sometimes to be unable to break through and it decays in its

infancy.

Dr. Lane says that, having found that the Italians made use of this

mushroom for food, he began eating it and introducing it to his friends,

and he learned by personal trial that it is a thoroughly good and

wholesome mushroom, which, when broiled with bacon, fried, baked or

stewed, may be eaten with perfect safety and that it is a nutritious

food. _Peck_, Bull. Torrey Bot. Club, Vol. 27, January, 1900.

=A. crenula´ta= Pk. =Pileus= thin, broadly ovate, becoming convex or

nearly plane and somewhat striate on the margin, adorned with a few thin

whitish floccose warts or with whitish flocculent patches, whitish or

grayish, sometimes tinged with yellow. =Lamellæ= close, reaching the

stem, and sometimes forming decurrent lines upon it, floccose crenulate

on the edge, the short ones truncate at the inner extremity, white.

=Stem= equal, bulbous, floccose mealy above, stuffed or hollow, white,

the annulus slight, evanescent. =Spores= broadly elliptic or subglobose,

7.5–10µ long, nearly as broad, usually containing a single large

nucleus.

=Pileus= 2.5–5 cm. broad. =Stem= 2.5–5 cm. long, 6–8 mm. thick.

Low ground, under trees. Eastern Massachusetts. September. _Mrs. E.

Blackford_ and _George E. Morris_.

The volva in this species must be very slight, as its remains quickly

disappear from the bulb of the stem. The remains carried up by the

pileus form slight warts or thin whitish areolate patches. The annulus

is present in very young plants, but is often wanting in mature ones, in

which state the plant might be mistaken for a species of Amanitopsis.

Its true affinity is with the tribe to which A. rubescens belongs. As in

that species, the bulb soon becomes naked and exhibits no remains of the

volva. It is similar to A. farinosa also in this respect, but quite

unlike it in color, in the adornments of the pileus and in the character

of its margin, which is even in the young plant and but slightly striate

in the mature state. Its dimensions are said sometimes to exceed those

here given, and it is reported to have been eaten without harm and to be

of an excellent flavor. I have had no opportunity to try. _Peck_, Bull.

Torrey Bot. Club, Vol. 27, January, 1900.

=AMANITOP´SIS= Roze.

_Amanita_; _opsis_, resembling.

Having a universal veil at first completely enveloping the young plant,

which soon bursts through, carrying particles of it on the pileus, where

they appear as scattered warts readily brushed off; the remainder or

volva closely enwraps the base of the stem. Ring absent. Spores white.

This genus was formerly included in Amanita. It differs from Amanita in

the absence of a ring or collar upon the stem and in the more sheathing

volva. It differs from Lepiota in having a volva.

Close observation is necessary in collecting Amanitopsis for the table.

_It has no trace of ring or veil upon the stem._ So far as the species

are known no poisonous one exists. But Amanita spreta Pk., which is

deadly, so closely resembles forms of Amanitopsis that those confident

of their knowledge will be deceived. The veil or traces of veil, which

Amanita spreta always has, sometimes so adheres to and wraps the stem

that it is not noticeable without close examination, thus giving to it

every appearance of an Amanitopsis.

The volva of A. spreta is attached for a considerable distance to the

base of the tapering stem, and is not readily removed. This is a guide

to detect it. It is a wolf in sheep’s clothing.

Amanitopsis corresponds to Volvaria in the pink-spored series, in which,

as far as known, there is no poisonous species.

All American species of Amanitopsis are given. Several have not been

tested by the writer because of lack of opportunity.

=A. vagina´ta= Roze—_vagina_, a sheath. (Plate X, figs. 1, 2, p: 28.)

=Pileus= thin, fragile, glossy, smooth except in rare instances where a

few fragments of the volva adhere to it for a time, deeply and

distinctly striate on the margin, sometimes umbonate. =Flesh= white, in

the dark forms grayish under the skin. =Stem= ringless, sometimes

smooth, but generally mealy or floccose, hollow or stuffed with a

cottony pith, _not bulbous_. =Volva= long, thin, fragile, closely

sheathing yet free from the stem, except in the lower part, easily

detachable and frequently remaining in the ground when the plant is

pulled. =Color= variable, generally mouse-gray, sometimes livid,

tawny-yellow or white, in one variety a rich date-brown. =Spores=

globose, 8–10µ broad _Peck_; elliptical 10×7–8µ _Massee_.

Var. _liv´ida_ Pers.—livid. Leaden brown, gills dingy. (Plate X, fig. 2,

p. 28.)

Var. _ful´va_ Schæff.—yellowish. Tawny-yellow or pale ochraceous.

This plant is widely dispersed, having been reported from many

localities in the United States, also from Nova Scotia and Greenland.

On ground in woods and on margins of woods, under trees, in shaded

grassy places. Sometimes in open stubble and pastures. June to frost.

Mt. Gretna, September, 1899, found a cluster on decayed chestnut stump.

Various colors abound—hazel, brown, gray, yellow, whitish. The caps and

stems are tender as asparagus tips, but without much distinct flavor

when cooked.

Great care must be taken to distinguish these forms from Amanita spreta

Pk. which is poisonous. See heading of genus—Amanitopsis.

=A. niva´lis= Grev.—snowy. (Plate X, fig. 3, p. 28.) =Pileus= at first

ovate, then convex or plane, smooth, _striate on the thin margin,

white_, sometimes tinged with yellow or ochraceous on the disk. =Flesh=

white. =Gills= subdistant, white, free. =Stem= equal, rather tall,

nearly smooth, _bulbous_, stuffed, white; the volva very fragile, _soon

breaking up into fragments or sometimes persisting in the form of a

collar-like ring at the upper part of the bulb_. =Spores= globose,

7.5–10µ in diameter.

=Plant= 4–6 in. high. =Pileus= 2–3 in. broad. =Stem= 2–4 lines thick.

July to October.

It approaches in some respects A. Frostiana, but its larger size, smooth

pileus, lighter color and the absence of an annulus will easily

distinguish it from that species. _Peck_, 33d Rep. N.Y. State Bot.

Specimens have been repeatedly found by the writer in open oak woods

near Philadelphia.

A strong, unpleasant bitter, which appears to develop while cooking,

renders it unpalatable. It is harmless, but its use is not advised.

=A. velo´sa= Pk.—_velosus_, fleecy. =Pileus= at first subglobose, then

bell-shaped or nearly plane, generally bearing patches of the remains of

the whitish felty or tomentose volva, elsewhere glabrous, becoming

sulcate-striate on the margin, buff or orange-buff. =Flesh= compact,

white. =Gills= close, reaching the stem, subventricose, pale cream

color. =Stem= firm, at first attenuated and tomentose at the top, then

nearly equal, stuffed, white or whitish, closely sheathed at the base by

the thick volva. =Spores= globose, 10–13µ.

=Pileus= 2–4 in. broad. =Stem= 3–4 in. long, 3–4 lines thick.

Under oak trees. Pasadena, California. April. _A.J. McClatchie._

This fungus is closely related to A. vaginata, from which it may be

separated by the more adherent remains of the thicker volva which

sometimes cover the whole surface of the pileus, and by the thicker

gills which are somewhat adnate to the stem and terminate with a

decurrent tooth. Bull. Torr. Bot. Club, Vol. 22, No. 12.

As it is probable this species will be found elsewhere than California,

and from its close relation to A. vaginata likely to be edible, its

description is here given.

=A. strangula´ta= (Fr.) Roze—choked, from the stuffed stem. (Plate X,

fig. 4, p. 28.) =Pileus= at first ovate or subelliptical, then

bell-shaped, convex or _plane, warty_, slightly viscid when moist,

_deeply and distinctly striate on the margin_, grayish-brown. =Gills=

free, close, white. =Stem= equal or tapering upward, stuffed or hollow,

nearly smooth, white or whitish, _the volva soon breaking up into scales

or subannular fragments_. =Spores= globose, 10–13µ.

=Plant= 4–6 in. high. =Pileus= 2–4 in. broad. =Stem= 3–6 lines thick.

_Peck_, 33d Rep. N.Y. State Bot.

_A. Ceciliæ_ B. and Br. is a synonym.

Not distinct in color and general appearance from A. vaginata, but

distinctly separated by its warty pileus and evanescent mouse-colored

volva which does not sheath the stem. =Pileus= striate when young, then

sulcate. =Stem= mealy, especially on the upper part.

Woods, open grassy places, wheat stubble, etc. June to September.

Pennsylvania, New Jersey, West Virginia, _McIlvaine_.

In the latitude of Philadelphia the plant is found in great abundance.

Its rather early appearance, staying quality, delicate consistency and

flavor make it valuable as a food supply.

Pearl color, bluish-gray and gray are the prevailing cap-coloring.

=A. adna´ta= (W.G.S.) Roze—_adnatus_, adnate, of the gills. =Pileus=

about 3 in. across. =Flesh= thick, whitish, firm, convex, then expanded,

rather moist, pale yellowish-buff, often furnished with irregular,

woolly patches of volva; margin even, extending beyond the gills. =Stem=

2–4 in. long, ½ in. thick, cylindrical, rough, fibrillose, pale buff,

flesh distinct from that of the pileus, stuffed, then hollow; base

slightly swollen. =Volva= adnate, white, downy, margin free and lax,

sometimes almost obsolete. =Gills= truly adnate, crowded, with many

intermediate shorter ones, white. =Spores= subglobose, with an oblique

point, 7–8µ _Massee_.

Tender, good flavor, yielding more substance when cooked than any other

Amanitopsis.

=A. volva´ta= Pk.—possessing a volva. =Pileus= convex, then nearly

plane, slightly striate on the margin, hairy or floccose-scaly, white or

whitish, the disk sometimes brownish. =Gills= close, free, white. =Stem=

equal or slightly tapering upward, stuffed, minutely floccose-scaly,

whitish, inserted at the base in a large, firm, cup-shaped, persistent

volva. =Spores= elliptical, 10×8µ.

=Plant= 2–3 in. high. =Pileus= 2–3 broad. =Stem= 3–4 lines thick.

_Peck_, 33d Rep. N.Y. State Bot.

The plant is easily recognized by its large, cup-shaped volva and cap,

which is not smooth, as is usual in a species with a persistent

membranous volva, more or less scaly with minute tufts of fibrils or

tomentose hairs. The gills are white in the fresh plant.

Professor Peck notes the species as quite rare. Numerous specimens occur

in the sandy oak woods of New Jersey, and in oak woods near Angora,

Philadelphia. July to October.

Care must be taken to determine the absence of an annulus or any trace

of one. Tender, delicate, without pronounced flavor. Equal to

Amanitopsis vaginata.

=A. farino´sa= Schw.—covered with _farina_, meal. =Pileus= nearly plane,

thin, _flocculent-pulverulent, widely and deeply striate on the margin_,

grayish-brown or livid-brown. =Gills= free, whitish. =Stem= whitish or

pallid, equal, stuffed or hollow, mealy, _sub-bulbous_, the volva

_flocculent-pulverulent_, evanescent. =Spores= variable, _elliptical

ovate or subglobose_, 6–8µ long.

=Plant= about 2 in. high. =Pileus= 1 in. to 15 lines broad. =Stem= 1–3

lines thick. July to September.

This is our smallest Amanita (now Amanitopsis). It is neither very

common nor very abundant when it does occur. It is described by

Schweinitz as “solid,” but I have always found it stuffed or hollow.

_Peck_, 33d Rep. N.Y. State Bot.

=A. pusil´la= Pk.—small. =Pileus= thin, broadly convex or nearly plane,

subglabrous, slightly umbonate, even on the margin, pale brown. =Gills=

narrow, thin, close, free, becoming brownish. =Stem= short, hollow,

bulbous, the bulb margined by the remains of the membranous volva.

=Pileus= _generally scaly_ from the breaking up of the cuticle and the

adherence of the concrete veil. =Gills= free, often very distant from

the stem and attached to a _cartilaginous_ collar. =Stem= hollow or

stuffed, its flesh distinct from that of the pileus. =Ring= at first

attached to the cuticle of the pileus, often movable, sometimes

evanescent.

On the ground. Several are found in hot-houses and hot-beds, and are

probably introduced species.

The universal veil, covering the entire plant when very young, is

closely applied to the pileus, which from the breaking up of the cuticle

is generally scaly. The =stem= in most species differs in substance from

the pileus. This is readily seen by splitting the plant in half from cap

to base. It is easily separated from the cap, leaving a cup-like

depression therein. =Gills= usually white. In some species they are

yellow-tinted. In others they become a dingy red when wounded or ageing.

The veil in this genus, being concrete with the cuticle of the pileus,

never appears as loose warts or patches, neither is there a volva as in

Amanita and Amanitopsis. These three genera are the only ones in the

white-spored series having gills free from the stem. In a few species

the gills are slightly attached to the stem, but are never decurrent

upon it as in Armillaria. When the plant is young it is egg-shaped. It

then gradually spreads, becomes convex, and opens until it is nearly

flat, with a knob in the center.

The only species in this genus known to be poisonous to some persons is

L. Morgani Pk., which is distinguished by its green spores and white

gills becoming green. L. Vittadini has also been regarded with

suspicion.

ANALYSIS OF TRIBES.

_A._ PILEUS DRY.

PROCERI (_L. procera_). Page 35.

=Ring= movable. The plant is at first entirely enclosed in a universal

veil, which splits around at the base, the lower part disappearing on

the bulb, the upper part attached to the pileus breaking up into scales.

=Stem= encircled at the top with a cartilaginous collar to which the

free, remote gills are attached.

CLYPEOLARII (_L. clypeolaria_). Page 39.

Ring fixed, attached to the upper portion of the universal veil which

_sheaths the stem_ from the base upward, making it downy or scaly below

the ring. The remainder of the veil united with the pileus breaking up

and becoming downy or scaly. Collar at the apex of stem not so large as

in Proceri, hence the gills are not usually so remote. Taste and smell

unpleasant, resembling that of radishes.

ANNULOSI (_annulus_, a ring). Page 44.

Ring _fixed_, somewhat persistent, universal veil closely attached to

the pileus. Collar absent or similar in texture to the stem. =Stem=,

_not sheathed_.

GRANULOSI (_L. granulosa_). Page 49.

Pileus _granular or warty_. Universal veil sheathing the stem, at first

continuous from the stem to the pileus, finally rupturing, forming a

ring nearer the base. Stem not so distinctly different from the pileus

as in other sections.

title).

The =Flesh= not very thick, soft, permanently white. =Pileus= at first

ovate, finally expanded, cuticle soon breaking up into brown scales,

excepting upon the umbo, umbo smooth, dark-brown, distinct. The caps

vary in shades of brown, sometimes they have a faint tinge of lavender.

=Gills= whitish, crowded, narrowing toward the stem, and very remote

from it. =Stem= variable in length, often very long, tubular, at first

stuffed with light fibrils, quite bulbous at base, generally spotted or

scaly with peculiar snake-like markings below the ring, which is thick,

firm and readily movable. When the stem is removed from pileus it leaves

a deep cavity extending nearly to the cuticle.

=Pileus= 3–6 in. broad. =Stem= 5–12 in. high, about ½ in. thick.

White spores elliptical, 14–18×9–11µ _Peck_; 12–15×8–9µ _Massee_; 14×10µ

Readily known by its extremely tall stem, shaggy cap, distinct umbo and

the channel between the gills and stem. Resembles no poisonous species.

Before cooking the scurf should be rubbed from the caps, which alone

should be eaten, as the stem is tough. Though the flesh is thin, the

gills are meaty and have a pleasant, nutty flavor. Fried in butter it

has few equals. It makes a superior catsup.

=L. racho´des= Vitt. _Gr._—a ragged, tattered garment. =Pileus= very

fleshy, but very soft when full grown, globose then flattened or

depressed, not umbonate, at first incrusted with a _thick, rigid_, even,

very smooth, bay-brown, wholly continuous _cuticle_, which remains

entire at the disk but otherwise _soon becomes elegantly reticulated

with cracks_; these very _readily separate_ into _persistent_,

polygonal, concentric _scales_, which are revolute at the margin and

attached to the surface with beautifully radiating fibers, the surface

remaining coarsely fibrillose-downy. =Flesh= white, _immediately

becoming saffron-red_ when broken, easily separating from the apex of

the distinct stem, which is encircled with a prominent collar. =Stem=

stout, at the first bulbous with a distinct margin upon the bulb,

conical when young, then elongated, attenuated upward, as much as a span

long, very robust, 1 in. thick, and more at the base, always even, and

_without a trace of scales_ or even of fibrils although the appearance

is obsoletely silky, wholly whitish, hollow within, stuffed with

spider-web threads, the walls remarkably and coarsely fibrous. =Ring=

movable, adhering longer to the margin of the pileus than to the apex of

the stem, hence rayed with fibers at the circumference, clothed beneath

with one or two zones of scales. =Gills= _very remote_, tapering toward

each end or broadest at the middle, crowded, whitish, sometimes

reddening. _Stevenson._

Veil remarkable in its development and thick margin.

A heavier species than L. procera, of which by some writers it has been

considered a variety, but it differs in the absence of umbo and flesh

becoming tinged with red.

Stem is decidedly swollen downward. Veil heavy, apparently double,

thickest at margin of cap to which it remains attached in heavy

fragments. It tears from the stem, leaving no mark of ring.

Var. _puella´ris_ Fr.—_puella_, a girl. Smaller than typical form,

shining white, pileus with downy scales. Not yet reported in America.

Edible qualities similar to those of L. procera. It is sold

=L. excoria´ta= Schaeff.—stripped of its skin. =Flesh= spongy, rather

thick, white, unchangeable. =Pileus= at first globose, then flat, hardly

umbonate, pale-fawn or whitish, disk dark; cuticle thin, silky or scaly,

sometimes areolate, more or less peeled toward margin, hence its name.

=Gills= ventricose, white, free, somewhat remote. =Stem= attenuated,
