Catalogued by Rev. M.A. Curtis, North Carolina, as edible.

Eaten in Italy. Inodorous, edible and agreeable. _Cordier._ More than

fair. I have often eaten it. _R.K. Macadam._

=PAXIL´LUS= Fr.

_Paxillus_, a small stake.

=Hymenophore= continuous with the stem, decurrent. =Gills=

membranaceous, somewhat branched, frequently anastomosing behind,

_distinct from the hymenophore and easily separable from it_. =Spores=

dingy-white or ferruginous.

_Fleshy putrescent fungi, margin of pileus at first involute, then

continually and gradually unfolding and expanding._ _Fries._

=Pileus= symmetrical or eccentric. =Stem= central, eccentric or wanting.

Edge of gills entire, sharp.

The marked features of this genus are the strongly involute margin, the

soft, tough, decurrent gills, separating readily from the flesh, and the

color of the spores.

The members of this genus possess some of the characters of Boletus. The

gills separate easily from the hymenophore as do the tubes of the

latter, and their anastomosing tendency is in P. porosus so marked that

the hymenium consists of large angular tubes. The gills of P. solidus B.

and C. form pores at the base, and its spores are elongated, both

features indicating an affinity with Boletus.

ANALYSIS OF TRIBES.

LEPISTA (a pan). Page 327.

Pileus entire, central. Spores dingy-white, in P. panæolus somewhat

rust-color. On the ground.

TAPINIA (to depress). Page —--.

Pileus generally eccentric or resupinate. Spores rust-color. On the

ground or on stumps.

So far as known the species of this genus are harmless. Many of them are

large, fleshy and inviting in appearance, but their flesh is usually dry

and coarse, and, though absorbent, is hard to cook tender. P.

atrotomentosus, which seems to be rare, is an exception. The flesh of

this species being firm in texture and readily made into a first-class

dish.

LEPIS´TA.

=P. lepis´ta= Fr.—_lepista_, a pan. =Pileus= 2–4 in. broad, flat or

depressed, dirty-white, smooth, sometimes minutely cracked near the

margin which is thin, involute and often undulate. =Stem= very variable

in length, 1–4 in., ½-¾ in. thick, dingy white or cream, solid, white

inside, equal, with a cartilaginous cuticle passing between the gills

and the flesh of the pileus, base blunt, villous, white. =Gills= very

decurrent, crowded, 2–3 lines broad, slightly branched but not at the

base, dingy-white becoming darker.

=Spores= reddish, becoming dingy brown. Broadly pyriforme 6×8µ _Massee_.

Pennsylvania. September, 1894. _McIlvaine._ Albion, N.Y., _Dr. Cushing_,

1898.

On ground in woods and margins of woods.

=Flesh= white. =Gills= narrow, crowded, brittle, decurrent, dingy-white

or pale-buff, easily separating from cap. =Stem= solid, elastic, at

length hollow, often short, an inch long, tapering downward, frequently

up to four inches in length and equal, base villose.

Resembling Lactarius piperatus and some forms of Clitocybe. It is

separated from the former by the absence of milk and from the latter by

its involute margin. The Clitocybe resembling it are all edible.

=Smell= strong, like old oily nuts. Edible but coarse.

=P. li´vidus= Cke. =Pileus= 1–2 in. across, convex, at length slightly

depressed at the disk, margin slightly arched and incurved, dingy-white,

or livid ochraceous, opaque. =Gills= decurrent, arcuate, almost crowded,

1½ line broad, white. =Stem= 3–4 in. long, ½ in. thick at the apex,

attenuated downward, white, fibrillose, stuffed then hollow, usually

rather flexuous. =Flesh= nearly white. =Spores= globose, 3–3.5µ

diameter, nearly white.

In woods. Usually in small clusters. Closely allied to Paxillus

revolutus, but distinguished by the absence of any tinge of violet on

the pileus or stem, and by the persistently white gills. _Massee._

Received from Katherine A. Hall, Danville, N.Y. October, 1898.

Raw it tastes like a drug-store smell. Edible, pleasant.

PAXILLUS INVOLUTUS.

One-half natural size.

]

=P. involu´tus= (Batsch) Fr.—_involutus_, rolled inward. =Pileus= 2–5

in. broad, fleshy, compact, convexo-plane then depressed, smooth, viscid

when moist, shining when dry, yellowish or tawny-ochraceous, _strongly

involute_, _margin densely downy_, flesh pallid. =Stem= 2–4 in. high,

about ½ in. thick, solid, firm, paler than the pileus, central or

eccentric. =Gills= 2–3 lines broad, crowded, branched, anastomosing,

_forming pores behind_, whitish then yellowish or rusty, _spotting when

bruised_.

=Spores= rust-color, ellipsoid or oblong-ellipsoid 8–16×6µ _K._; 5×6µ

_W.G.S._ Elliptical, 8–10µ _Peck_.

It grows singly or in groups and likes damp mossy soil. Common in cool

hemlock or spruce woods in the Adirondack mountains; not rare in the

mixed woods of all our hilly districts. When growing on decayed stumps

the stem is sometimes eccentric. August, November. _C.H. Peck._

In open woods near Haddonfield, N.J., it grows to a large size and in

quantity. In Angora woods near Philadelphia a complete ring of it 20 ft.

in diameter was seen.

Considered edible throughout Europe and said to be highly esteemed in

Russia. The flesh of the American plant is dry and coarse, does not cook

tender and is rather tasteless.

=P. a´tro-tomento´sus= (Batsch.) Fr.—_ater_, black; _tomentum_, down.

=Pileus= 3–6 in. broad, rust-color or reddish-brown, compactly fleshy,

eccentric, convex then plane or depressed, margin thin, frequently

minutely rivulose, sometimes tomentose in the center. =Flesh= white.

=Stem= 3–6 in. high, ½-1 in. thick, stout, solid, elastic, eccentric or

lateral, unequal rooting, _covered with dense velvety down, very dark

brown_. =Gills= adnate, 3 lines broad, close, anastomosing at the base,

yellowish, interspaces venose.

=Spores= subhyaline 4–6×3–4µ _K._ Elliptical, pale-yellowish, 5×2.5–3µ

_Massee_. Elliptical 5–6×4µ _Peck_.

Found near Philadelphia, gregarious in old woods. September. In New

Jersey in pine woods on stumps and on the ground, probably growing from

roots. _McIlvaine._

Grows singly or cespitose, sometimes in large tufts, when the pileus is

frequently irregular from compression. In wet weather the pileus is

moist and sometimes obscurely mottled with dark spots. Occasionally it

has an unpleasant dirt-like odor. _Peck._

Cordier considers this species suspicious and Paulet inutile on account

of its bad taste.

The flesh differs from most Paxilli in being very fine grained and

cooked is of the consistency of a marshmallow. The taste is marked but

pleasant.

_Series IV._ =PORPHYRO´SPORÆ= (Pratelli). _Gr_—purple.

Spores typically black-purple or brownish-purple, more rarely dusky

brown. (It is to be observed that the spores vary in color according to

the color of the ground on which they are deposited.) There are sterile

forms with the gills persistently white (A. obturatus, A. udus). Those

species are more deceptive in which the gills continue for a long time

white, and even begin to decay before they are discolored by the spores;

these may be easily mistaken for Leucospori. _Fries._

Pratelli is the name given by the early authors to this series, based

upon the spore color; Porphyrosporæ is the name now used. The species

within the group are closely allied to those having black spores without

a tinge of purple or violet (Melanosporæ), but in none of the species do

the gills deliquesce as in Coprinus, neither are there resupinate or

lateral stemmed species.

There is a present tendency to do away with this series and include all

dark-spored species in the Melanosporæ. Professor Atkinson and Bertha

Stoneman, in their “Provisional Key to the Genera of Hymenomycetes,”

omit the series and give “Melanosporæ, Gill and Butz (Pratellæ and

Coprinariæ in broadest sense). Spores dark brown, purplish-brown or

black.”

It is frequently difficult to determine by the spore-color of this

AGAR´ICUS.

_Agaricon_, a Greek name for fungi, said to be derived from the name of

a town, Agara.

=Pileus= fleshy, flesh of the stem different from that of the pileus,

furnished with a distinct ring. =Gills= at first enclosed by the veil,

free, rounded behind, at first white or whitish, in some species this

stage lasting but a short time, then pink or reddish, at length dark

purplish-brown from the spores. =Spores= brown, brownish or

reddish-purple.

On the ground, generally in pastures, meadows or manured ground, a few

species occur in woods.

Analogous with Lepiota of the white-spored series. Stropharia also bears

a ring and has similar colored spores, but is separated by the flesh of

stem and pileus being continuous and the gills being more or less

adnate.

Formerly in Agaricus as sub-genus Psalliota (_psallion_, _psalion_, in

poetry, a ring). When Psalliota was raised to generic rank it was given

the name of the great genus Agaricus as a mark of distinction on account

of its including the most widely known and useful mushroom of the

world—Agaricus campester. The name Psalliota is not in modern use.

Old Agaricus included many subgenera and consequently many more species.

Now it contains but few. All of them are highly flavored and of marked

excellence. Before the subgenera under Agaricus were promoted to full

generic standing it was customary to state the name of a species thus:

Agaricus (Psalliota) campester. Agaricus (Stropharia) semi-orbicularis.

This was lengthy and clumsy. In the older books this form prevails.

Often, however, the subgenus is omitted before the name, which compels

the student to look up the subgenus to which the species belongs. The

older books are therefore puzzling to modern students, who find there

simply the name Agaricus to guide them. The present genus of a known

species in old Agaricus can be easily found by looking in the index for

its specific name. The name of the genus follows it in parentheses.

All of the genus can be cooked in any desired way.

then expanded with decurved margin or nearly plane, smooth, silky

floccose or hairy squamulose, the margin extending beyond the lamellæ,

the flesh rather thick, firm, white. =Lamellæ= free, close, ventricose,

_at first delicate pink or flesh color_, then blackish-brown,

_subdeliquescent_. =Stem= equal or slightly thickened toward the base,

The varieties of A. campester are numerous. All of them are edible and

vary but slightly in their excellence.

Var. _al´bus_ Berk.—_albus_, white. A very common wild form. =Cap= 2–4

in. across, smooth or slightly fibrillose. =Stem= 1½-3 in. long, ⅓-⅔ in.

thick, white or whitish. Spring to autumn, in rich grassy places.

Sometimes very large. It is cultivated.

Var. _gri´seus_ Pk.—_griseus_, gray. =Cap= grayish, silky, shining.

=Ring= vanishing. Reported from Virginia.

Var. _prati´cola_ Vitt.—_pratum_, a meadow; _colo_, to inhabit. Meadow

variety. =Cap= covered with reddish scales. =Flesh= pinkish. Parade

ground, Mt. Gretna, Pa.

Var. _umbri´nus_ Vitt.—_umber_, dark brown. =Cap= brown, smooth. =Stem=

short, minutely scaly.

“Var. _rufes´cens_ Berk.—_rufescens_, becoming red. =Pileus= reddish,

minutely scaly. =Gills= at first white. =Stem= elongated. =Flesh=

turning bright red when cut or bruised. This departs so decidedly from

the ordinary characters of the type, especially in the white color of

the young gills, that it seems to merit separation as a distinct

species.” _Peck_, 36th Rep.

Var. _villa´ticus_ Brond.—belonging to a villa. =Cap= scaly. =Stem=

scaly.

Var. _horten´sis_ Cke.—growing in gardens. =Cap= brownish or

yellowish-brown, covered with fibrils or minute hairs. This is a

cultivated species.

“Var. _Bu´channi_. =Cap= white, smooth, depressed in center, the margin

naked. =Stem= stout. =Ring= thin, lacerated. A rare variety, sometimes

occurring in mushroom beds.

“Var. _elonga´tus_—elongated. Long-stemmed variety. =Pileus= small,

smooth, convex, the margin adorned with the adherent remains of the

lacerated veil. =Stem= long, slender, slightly thickened toward the

base. =Ring= slight or evanescent. This is also a variety of mushroom

beds.

“Var. _vapora´rius_. Green-house variety (A. vaporarius Vitt.) =Pileus=

brownish, coated with long hairs or fibrils. =Stem= hairy-fibrillose,

becoming transversely scaly. Conservatories, cellars, etc. Not differing

greatly from Var. hortensis.” _Peck_, 36th Rep. N.Y. State Bot.

The A. campester is known the world over as the common mushroom. It is

cosmopolitan, appearing in pastures and rich places from spring and

until long after severe frosts. It is the sweet morsel of gourmets.

Indirectly it has done more damage than the assembled viciousness of all

other toadstools. It is by mistaking the young button forms of the

deadly Amanita for the button forms of the common mushroom that most

cases of fatal toadstool poisoning are brought about. It is, also,

usually the persons who think they know the mushroom, and can not be

deceived, that get poisoned. If two rules are observed danger can be

avoided. (1) Never eat a fungus gathered in the woods believing it to be

the mushroom. The typical A. campester does not grow in the woods;

species of Agaricus somewhat resembling it do. (2) Look at the gills;

those of the mushroom are at first a light-pink which rapidly, as the

plant matures, darken to a dark-brown, purplish-brown, or

purplish-black. This is due to the ripening of the spores. Those of the

Amanita are constantly white.

Pages could be written upon the mushroom and its culture, and recipes

for the cooking of it would fill a volume. One important thing is

omitted from them all—it is culinary heresy to peel a mushroom. Much of

the flavor lies in the skin, as it does in that of apples, apricots,

peaches, grapes, cherries and other fruits. The mushroom should be wiped

with a coarse flannel or towel until the skin is clean. See chapter on

cooking, etc.

Lafayette B. Mendel, in American Journal of Physiology, March, 1898,

gives the following analysis of A. campester:

Two varieties of the common mushroom were collected in New Haven.

Fifteen specimens of one variety weighed 1½ ounce, an average weight of

43 grains each. The analysis gave:

_a._ _b._

Water 87.88% 92.20%

Total solids 12.12 7.80

Total nitrogen in dry 4.42 4.92

substance

Ash in dry substance 11.66 17.18

=A. comp´tulus= Fr.—_comptus_, gaily adorned. =Pileus= 1–1½ in. broad,

_yellowish-white_, slightly fleshy, convex then plane, obtuse,

_adpressedly fibrilloso-silky_, becoming even. =Flesh= thin, soft, of

the same color as the pileus. =Stem= 2 in. long, 2–3 lines thick,

_hollow_, stuffed with floccules when young, _somewhat attenuated_,

even, smooth, white, becoming somewhat light yellow. =Ring= medial,

torn, _fugacious_, of the same color. =Gills= rounded-free behind,

crowded, soft, broader in front, _flesh-color_ then _rose_, not

dingy-flesh-color except when old.

Closely allied to A. campestris, but constantly distinct in its more

beautifully colored gills. _Fries._

A. comptulus appears frequently in the latitude of Philadelphia. It is a

neat species, but not substantial in flesh. Here it usually grows close

to the ground. The ring is very evanescent.

Its edible qualities are those of A. campester.

=A. silvat´icus= Schaeff.—belonging to woods. =Pileus= thin, at first

convex or bell-shaped, then expanded, _gibbous or subumbonate_,

fibrillose or variegated with a few thin tawny brownish or reddish-brown

_spot-like adpressed scales_, whitish, brownish or smoky-gray, the disk

sometimes tinged with red or reddish-brown, the flesh white or faintly

reddish. =Lamellæ= thin, close, free, narrowed toward each end, reddish,

then blackish-brown. =Stem= rather long, _equal or slightly tapering

upward_, hollow, whitish. =Spores= elliptical, 5–6.5×4–5µ.

In taste and smell A. silvaticus resembles A. silvicola, but is

stronger. It is a frequent but not common species in the localities

where I have found it. Quantities of it have not occurred, but myself

and friends have eaten it for years, knowing no distinction in effect

between it and allied species. Its strong taste requires that it be well

cooked. It does not lose its high flavor, which may be objectionable to

some. I prefer using its juices as a flavoring.

=A. diminuti´vus= Pk.—diminutive. =Pileus= thin, fragile, at first

convex, then plane or centrally depressed, sometimes slightly umbonate,

whitish or yellowish, faintly spotted with small thin silky appressed

brownish scales, the disk brownish or reddish-brown. =Lamellæ= close,

thin, free, ventricose, brownish-pink becoming brown, blackish-brown or

black. =Stem= equal or slightly tapering upward, stuffed or hollow,

smooth, pallid. =Annulus= thin, persistent, white. =Spores= elliptical

5×4µ.

=Plant= 1.5–2 in. high. =Pileus= 1–1.5 in. broad. =Stem= 1–2 lines

thick.

Woods. Croghan and Sandlake, N.Y. August. Autumn.

This is a small but symmetrical and beautiful Agaric. It is perhaps too

closely related to the preceding species (A. silvaticus), of which it

may possibly prove to be a mere variety or dwarf form. Its pileus is

quite thin and fragile. Usually the darker or reddish hue of the disk

gradually loses itself in the paler color of the margin, but sometimes

the whole surface is tinged with red. _Peck_, 36th Rep. N.Y. State Bot.

Chester county; West Philadelphia, Pa., September; Mt. Gretna, Eagle’s

Mere, Pa., August. _McIlvaine._

I have found A. diminutivus so intimately associated with A. silvaticus

that its being a dwarf form of the latter seemed more than probable. Its

edible qualities are the same.

=A. Rod´mani= Pk. =Pileus= rather thick, firm, at first convex, then

nearly or quite plane, with decurved margin, smooth or rarely slightly

cracked into scales on the disk, white or whitish, becoming yellowish or

subochraceous on the disk, the flesh white, unchangeable. =Lamellæ=

close, _narrow_, rounded behind, free, reaching nearly or quite to the

stem, _at first whitish then pink or reddish-pink_, finally

blackish-brown. =Stem= short, subequal, solid, whitish, smooth below the

ring, often scurfy or slightly mealy-squamulose above; ring variable,

thick or thin, entire or lacerated, at or below the middle of the stem.

=Spores= broadly elliptical or subglobose, generally uninucleate,

5–6×4–5µ.

=Plant= 2–3 in. high. =Pileus= 2–4 in. broad. =Stem= 6–10 lines thick.

Grassy ground and paved gutters. Astoria, L.I. _Rev. W. Rodman_.

Washington Park, Albany. May to July.

This species is intermediate between A. campestris and A. arvensis, from

both of which it may be distinguished by its narrow gills, solid stem

and smaller, almost globose, spores. In size, shape of the pileus and

general appearance it most resembles A. campestris, but in the whitish

primary color of the gills and in the yellowish tints which the pileus

often assumes, it approaches nearer to A. arvensis. * * * _Peck_, 36th

Rep. N.Y. State Bot.

I can now add my own testimony to that of Mr. Rodman as to its

edibility. Its flesh is firm but crisp, not tough, and its flavor,

though not equal to that of the common mushroom, is nevertheless

agreeable, and its use as food is perfectly safe. _Peck_, Rep. 49.

This species has grown freely for several years at Hull and Cohasset,

Mass. It is usually found about June 1st, and is not seen again until

early autumn. It is the handsomest mushroom I have seen, and its edible

qualities are on a par with its appearance. _Macadam._

=A. hæmorrhoida´rius= Shulzer. _Gr_—discharging blood. =Pileus= 4 in.

across, reddish-brown, fleshy, ovate then expanded, _covered with broad

adpressed scales_, margin at first bent inward. =Flesh= when broken

immediately blood-red. =Stem= 4 in. high, 1 in. thick, soon hollow,

fibrillose, the solid base somewhat bulbous. =Ring= superior, large.

=Gills= free, approximate, crowded, rosy-flesh-color, at length

purple-umber.

Very striking, 3–4 in. high. The pileus and the white stem become

spotted blood-red when touched. The stem when young is adpressedly

squamulose below, when full grown mealy, becoming smooth. _Fries._

=Spores= purple-brown, 7–8×5µ Massee; brown, elliptical, 5–6×4µ _Peck_.

A rare or overlooked plant in United States, first recorded by Professor

Peck, who found it but once, growing under a hemlock tree. Rep. 45.

Nebraska, _Clements_; West Virginia; Eagle’s Mere and Mt. Gretna, Pa. In

hemlock and mixed woods. Autumn. _McIlvaine._

=Cap= 2–4 in. across. =Stem= 3–4 in. long, up to ¾ in. thick.

Every part of the plant turns red and has a congested appearance when

bruised. The flesh is white but immediately becomes red when broken.

It is a frequent but not common species, growing singly, or in small

clusters.

In flavor and substance it is equal to any mushroom.

=A. mari´timus= Pk. =Pileus= very fleshy, firm, at first subglobose,

then broadly convex or nearly plane, glabrous, sometimes slightly

squamose with appressed spot-like scales, white becoming dingy or

grayish-brown when old. =Flesh= whitish, quickly reddening when cut,

taste agreeable, odor distinct, suggestive of the odors of the seashore.

=Lamellæ= narrow, close, free, pinkish becoming purplish-brown with age,

the edge white. =Stem= short, stout, firm, solid, equal, sometimes

bulbous, white, the annulus delicate, slight and easily obliterated.
