Part 33

=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. =Spores= broadly elliptic, purplish-brown, 7–8µ long, 5–6µ broad.

=Pileus= 2–8 in. broad. =Stem= 1–2 in. long, .6 in. thick.

Sandy soil near salt water, Lynn, Mahant and Marblehead, Mass. June to December. _R.F. Dearborn._

This is a very interesting and an excellent mushroom. Dr. Dearborn writes that he has used it on the table for fourteen years and that it is the only mushroom that he has ever eaten in which the stem is as good as the cap. He considers it the most hearty and satisfying of all the numerous species that he has ever eaten. Both its taste and odor is suggestive of the sea. The latter is quite strong, and perceptible by one riding along the road by whose side the mushrooms are growing. They sometimes grow in semicircles and attain a larger size in warm weather than in the colder weather of autumn. They are most abundant in August. The flesh, when cut or broken, quickly assumes a pink or reddish hue on the freshly-exposed surface. This is a very distinctive character and with the maritime habitat makes the species easy to recognize. Another species, Agaricus hæmorrhoidarius Kalchb. exhibits a similar change of color in its wounded flesh, but is of very rare occurrence with us, does not, so far as ascertained, grow near the sea, has a darker cap and a long hollow stem. The stem in the maritime mushroom is short and solid. Its collar is very slight and easily destroyed. _Peck_, Bull. Torr. Bot. Club, Vol. 26, No. 2, F. 1899.

=A. Califor´nicus= Pk.—=Pileus= at first subconical, becoming convex, minutely silky or fibrillose, whitish, tinged with purple or brownish-purple on the disk. =Flesh= whitish. =Gills= close, free, pink becoming purplish, then blackish-brown. =Stem= rather long, solid or stuffed, equal or tapering upward, distinctly and rather abruptly narrowed above the entire externally silky ring, pallid or brownish. =Spores= broadly elliptical, 5–6×4–5µ.

=Pileus= 1–3 in. broad. =Stem= 1.5–3 in. long, 2–4 lines thick.

Under oak trees. Pasadena. January. _McClatchie._

This fungus is similar in size, shape and habitat to A. hemorrhoidarius, but it is unlike that species in color, in the adornment of the pileus and in its color not changing where bruised or broken. Bull. Torr. Bot. Club, 22–5 My. 95.

=A. Elven´sis= B. and Br.—Name from river Elwy, Wales, where first found. Tufted. =Pileus= 4–6 in. or more across, subglobose then hemispherical, fibrillose, broken up into large persistent brown scales, areolate in the center, margin very obtuse, thick, covered with pyramidal warts. =Stem= at first nearly equal, at length swollen in the center, and attenuated at the base, 4–6 in. high, 2 in. thick in the center, fibrillose and areolate below, nearly smooth within the pileus, solid, stuffed with delicate threads. =Ring= thick, very large, deflexed, broken here and there, warted in areas beneath. =Gills= rather crowded, ¼ in. broad, free, of a brownish flesh-color. =Spores= elliptic oblong, 8×4µ.

Under oak trees, etc. Edible, delicious eating. Flesh of pileus ¾ in. thick, red when cut. _Massee._

California, _H. and M._

Edible. _Cooke_, 1891.

=A. f[oe]dera´tus= Berk. and Mont.—confederated. =Pileus= fleshy, thin, at first ovoid then bell-shaped, finally convex, somewhat umbilicate with the center slightly depressed, margin hanging down (when dry involute), fragments of the veil hanging from the margin, tawny, scaly with minute, scattered, white, persistent granules, 2–3 in. broad, ¾-1½ in. high.

Lawns and grassy places in rich soil. Often associated with Stropharia bilamellata Pk. After rains from April to November. Washington, D.C. _F.J. Brændle._

This is a small mushroom, peculiar in having the young gills of a dark color and in the absence of any pink hues. The gills sometimes become moist and manifest a tendency to deliquesce. The drying specimens emit a strong but not unpleasant odor. Mr. Brændle says that their edible quality is excellent and that it is not impaired by drying. _Peck_, Bull. Torr. Bot. Club, Vol. 26, F. 1899.

=A. praten´sis= Schaeff.—a meadow. =Pileus= 2–3½ in. across, ovoid then expanded, becoming smooth or sometimes broken up into scales more or less concentrically arranged, whitish, then grayish. =Flesh= thick in the center, thin toward the margin, white. =Gills= free, rounded behind, about ¼ in. broad, grayish, then brown. =Stem= about 2 in. long, ½-⅔ in. thick, base thickened, smooth, whitish. =Ring= median, simple, usually deciduous. =Stem= becoming more or less hollow. =Spores= elliptical, apiculate, 6×3.5µ.

On pastures and woods. Distinguished by the grayish gills becoming brown without any intermediate pink or fleshy tinge, and in being rounded behind, the median deciduous ring, and the more or less hollow stem. _Massee._

California. Common. Edible. _H. and M._ Not elsewhere reported.

=A. achi´menes= B. and C. _Gr_—an amber-colored plant. =Pileus= 4–6 in. broad, pallid or yellowish-white, smooth like kid leather, but studded with warty excrescences especially toward the center. =Stem= 4–6 in. high, 3–4 lines thick, white, stuffed with floccose fibers, furnished toward the apex with a large deflexed ring. =Gills= broad, crowded at first, whitish then ash-colored and dingy-brown, free. =Spores= brownish, oval or ovate.

A splendid species allied to A. fabaceus, but differing in its paler spores, warty cap, ample ring, etc.

On the earth. Solitary. June. _S.C. Ravenel._ Am. Jour. Sci. and Arts, 1849.

I have not seen this species.

=A. faba´ceus= Berk.—relating to beans. =Pileus= 4–5 in. across, thin, almost submembranaceous, umbonate, conical when young, becoming nearly plane as it expands, white, viscid when moist; epidermis smooth, tough, feeling like fine kid leather, turning yellow when bruised. =Stem= 3–4 in. high, ⅓ in. thick, white, smooth, with the exception of a few fibrilla, equal except at the base. =Veil= large, at first covering the gills and connecting the margin with the stem, white, externally floccose. =Gills= crowded, very thin, not ventricose, free, brown when young, then darker brown, at length almost black like the dark part of a bean flower. A fine species allied to A. arvensis. When young it has a peculiar but not unpleasant smell. On the ground, amongst dead leaves in open woods. Waynesville, September 10, 1844. Hooker’s London Jour. of Botany, 1847.

Described by Berkeley from specimens collected by Thomas G. Lea, in the vicinity of Cincinnati.

On ground among old leaves in woods. Common. =Pileus= 3–4 in. broad. =Stem= 3–4 in. high. =Spores= brown, nucleate on one side, small, 5.5µ long. _Morgan._

This is among the most delicious species for the table. Fresh specimens have a distinct taste and odor of peach kernels or bitter almonds which is nearly lost in cooking. Am. Jour. Science and Arts, 1850. _Curtis._

*** _Gills at first whitish._

=A. arven´sis= Schaeff.—belonging to cultivated ground. HORSE MUSHROOM, PLOWED-LAND MUSHROOM. (A. Georgii Sow., A. pratensis Scop., A. edulis Krombh., A. exquisitus Vitt.) =Pileus= at first convex or conical, bell-shaped then expanded, at first more or less floccose or mealy, then smooth white or yellowish. =Flesh= white. =Gills= close, free, generally broader toward stem, _at first whitish, then pinkish_, finally blackish-brown. =Stem= equal or slightly thickened toward the base, smooth, _hollow or stuffed_ with a floccose pith; ring rather large, thick, the lower or exterior surface often cracked in a radiate manner.

=Plant= 2–5 in. high. =Pileus= 3–5 in. or more broad. =Stem= 4–10 lines thick.

Cultivated fields and pastures. Summer and autumn.

This species is so closely related to the common mushroom that it is regarded by some authors as a mere variety of it. Even the renowned Persoon is said to have written concerning it: “It appears to be only a variety of A. campestris.” Fries also says that it is commonly not distinguished from A. campestris, but that it is diverse in some respects; its white flesh being unchangeable, its gills never deliquescing, remaining a long time pale and not becoming dark-red in middle age. Berkeley says of it: “A coarse but wholesome species, often turning yellow when bruised.” _Peck_, 36th Rep. N.Y. State Bot.

=Spores= spheroid-elliptical, 9×6µ _K._; 11×6µ _W.G.S._; elliptical, 8–10×5–6.5µ _Peck_.

Indiana, _H.I. Miller_; Minnesota, _B.L. Taylor_; West Virginia, North Carolina, New Jersey, Pennsylvania, _McIlvaine_.

Unless the numerical system of John Ph[oe]nix to express degrees of quality is adopted by a mycophagists' congress, and one species of fungus is chosen as the standard of excellence, the comparative excellence of species will never be settled. English epicures shun A. arvensis; the French prefer it. Berkeley says it is inferior to the common mushroom; Vittadini says it is very sapid and very nutritious. So opinion varies. Individual tastes must decide excellence. Comparison never will. Toadstools differ in substance, texture and taste as one meat or vegetable differs from another. Beef could not be chosen as the standard for meats, or cabbage as the standard for vegetables. Agaricus arvensis is good.

PAGE. AGARICUS MAGNIFICUS. PECK, 342

A new species of Agaricus.

=A. magni´ficus= Pk.—magnificent. (Plate XCIV.) =Pileus= 5–15 cm. (2–6 in.) broad, fleshy, thick, convex, becoming nearly plane or centrally depressed, bare, often wavy and split on the margin, white or whitish, often brownish in the center. =Flesh= 1.5–2 cm. (½ in.) thick in the center, thin on the margin, white, unchangeable. =Gills= numerous, rather broad, close, free, ventricose, white becoming dark purplish brown with age, never pink. =Stem= 10–15 cm. long (4–6 in.), about 2.5 cm. thick (1 in.), firm, stuffed with cottony pith, bulbous or thickened at the base, fibrillose, striate, minutely furfuraceous (covered with scurf) toward the base, ringed, pallid or whitish, the ring thin, persistent, white. =Spores= small, elliptic, 5–6µ long, 3–4µ broad.

Gregarious or cespitose; thin woods, Mt. Gretna, Pa. August. _Charles McIlvaine._

A large fine species distinguished from its near allies by the absence of pink hues from the gills. Mr. McIlvaine remarks that it has an anise-like flavor and odor and that when young the whole fungus is tender and high flavored, but when full grown the caps only are edible. _Peck_, Bull. Torr. Bot. Club, Vol. 26, F. 1899.

=A. silvic´ola= Vitt.—_silva_, a wood; _colo_, to inhabit. (Plate XCI, fig. 2, p. 332.) (A. arvensis, var. abruptus Pk.; now A. abruptus Pk.) =Pileus= convex or sub-bell-shaped, sometimes expanded or nearly plane, _smooth, shining_, white or yellowish. =Gills= close, thin, free, rounded behind, generally narrowed toward each end, _at first whitish, then pinkish_, finally blackish-brown. =Stem= _long_, cylindrical, stuffed or hollow, white, _bulbous_; ring either thick or thin, entire or lacerated. =Spores= elliptical, 6–8×4–5µ.

=Plant= 4–6 in. high. =Pileus= 3–6 in. broad. =Stem= 4–8 lines thick.

Woods, copses and groves or along their borders. Summer and autumn. _Peck_, 36th Rep. N.Y. State Bot.

Very good eating, though scarcely as highly flavored as the common mushroom. _Peck._

West Virginia, Pennsylvania, New Jersey, June to frost. _McIlvaine._

A. silvicola, by many authors considered a variety of A. campester, is, seemingly, becoming common. Professor Peck in 46th Rep. has made the abrupt bulb and its usual double veil distinctive marks which ally it to A. arvensis. He therefore calls it var. abruptus. As this book goes to press Professor Peck writes me that he concludes var. abruptus to be a good and distinct species. It is therefore given as such. While familiar with it since 1881, I never found it in quantity until 1898, at Mt. Gretna, Pa. There, among the straw and rubbish of abandoned camps on wood margins, it grew in great quantity; sometimes singly, at others in crowded clusters. When growing singly it exhibits all the characteristics of its description; when clustered, the stems are not always bulbous. The caps are thin but fleshy, brittle and bear a disproportionate width to the stem—like a plate on a pipe stem. The caps when mature are usually tinged with yellow and are spread flat; the ring is large, often double, yellowish, often torn, fragments of it frequently hang from the cap margin; the bulb when perfect is small, abrupt, as if it had once been round but the stem pushed into it. It has a strong spicy mushroom odor and taste, and makes a high-flavored dish. It is delicious with meats. It is the very best mushroom for catsup. Mixed with Russulæ or Lactarii or other species lacking in mushroom flavor, it enriches the entire dish. The stems, excepting of the very young, are tough.

Larvæ do not infest A. silvicola. Its habit of growth shows it to be cultivatable. It has but one draw-back. Growing as it does in woods and in the presence of the poisonous Amanita, it is possible for the careless collector to confound the two. The Amanitæ have larger bulbs, cups at the base, and _white gills_; the A. silvicola has no volva, has whitish gills when very young only, they become pinkish, then a marked blackish-brown.

=A. creta´ceus= Fr.—_creta_, chalk. =Pileus= 3 in. and more broad, wholly _white_, fleshy, lens-shaped-globose when young, then convexo-flattened, obtuse, dry, _sometimes even_, sometimes rivulose chiefly round the margin from the cuticle _separating into squamules_. =Flesh= thick, white, unchangeable. =Stem= 3 in. long, 3–6 lines and more thick, _hollow, stuffed with a spider-web pith_, firm, attenuated upward, even, smooth, not spotted, white. =Gills= free, then remote, ventricose but _very much narrowed toward the stem_, crowded, _remaining long white_, becoming dingy-brown only when old. _Fries._

=Spores= 3×4µ _W.G.S._; 5–6×3.5µ _Massee_.

Under certain conditions the spores are white. _M.J.B._

In lawns and rich ground.

North Carolina, on earth and wood. Edible, _Curtis_; Minnesota, rare, _Johnson_; California, _H. and M._; Ohio, _Lloyd_; Kentucky, _Lloyd_, Rep. 4; New York, _Peck_, Rep. 22.

=A. subrufes´cens= Pk.—_sub_, under; _rufescens_, becoming red. =Pileus= at first deeply hemispherical, becoming convex or broadly expanded, silky fibrillose and minutely or obscurely scaly, whitish, grayish or dull reddish-brown, usually smooth and darker on the disk. =Flesh= white, unchangeable. =Lamellæ= at first white or whitish, then pinkish, finally blackish-brown. =Stem= rather long, often somewhat thickened or bulbous at the base, at first stuffed, then hollow, white; the annulus flocculose or floccose-scaly on the lower surface; mycelium whitish, forming slender branching root-like strings. =Spores= elliptical, 6–7µ _Peck_, 48th Rep. N.Y. State Bot.

Indiana, _H.I. Miller_, 1898; Haddonfield, N.J., _McIlvaine_.

June 2, 1896, I found several specimens of a fungus new to me, and sent them to Professor Peck for identification. He pronounced it a dwarf form of his species A. subrufescens. The cluster grew on a florist’s compost pile at Haddonfield, N.J. Its flesh has a flavor like that of almonds.

This species is now cultivated and has manifest advantages over the marketed species—it is easier to cultivate, very productive, produces in less time after planting the spawn, is free from attacks of insects, carries better and keeps longer.

Amateurs are likely to succeed in growing it, and to have goodly crops of mushrooms instead of disappointments.

=A. placo´myces= Pk. _Gr_—a flat cake. (Plate XCI, fig. 3, p. 332.) =Pileus= thin, at first convex, becoming flat with age, whitish, brown in the center and elsewhere adorned with minute brown scales. =Lamellæ= close, white, then pinkish, finally blackish-brown. =Stem= smooth, annulate, stuffed or hollow, bulbous, white or whitish, the bulb often stained with yellow. =Spores= elliptical, 5–6.5µ long.

=Cap= 2–4 in. broad. =Stem= 3–5 in. long, ¼ to nearly ½ in. thick.

It grows in the borders of hemlock woods or under hemlock trees from July to September. It has been eaten by Mr. C.L. Shear, who pronounces it very good. I have not found it in sufficient quantity to give it a trial. This mushroom is very closely related to the wood mushroom or silvan mushroom, Agaricus silvaticus, a species which is also recorded as edible, but which is apparently more rare in our state (New York) than even the flat-cap mushroom. This differs from the silvan mushroom in its paler color, in having the cap more minutely, persistently and regularly scaly, and in its being destitute of a prominent center. In the silvan mushroom the scales, when present, are few, and they disappear with age. _Peck_, 48th Rep. N.Y. State Bot.

Mrs. E.C. Anthony, Gouverneur, N.Y., June, 1898, writes: “In great abundance on lawn, tumbling over one another in their haste to make their appearance. One of the largest, which did not have half a chance to display its proportions, would probably measure 7 in., perhaps more. When mature they crack across the top, showing the white flesh. The gills are pink, stem white, solid and bulbous. There is no perceptible odor when fresh.”

Indiana, _H.I. Miller_, edible, good.

Specimens sent to me by Mrs. Anthony, though not fresh, were eaten by me. They very much resembled the common mushroom, but probably, owing to their condition, were not so tender.

I have not found the species. The illustration is after a painting by Mrs. E.C. Anthony.

=A. varia´bilis= Pk.—variable. (Plate XCI, fig. 1, p. 332.) =Cap= 2–6 in. across, ovate, bell-shaped, irregularly convex and wavy, margin incurved but never striate, smooth, minutely fibrillose, with few remaining floccose scales; mature plant pure white, when young distinctly tinged with lilac and here and there with yellow when mature, slightly, broadly umbonate and depressed around umbo, cracks along gills. =Flesh= thick in center, very thin, even membranaceous toward margin, spongy, unchangeable. =Gills= free, close, thin, flaccid, ventricose, narrow next stem, but few short, pure-white when young, then dark-umber without purple tinge. =Stem= equal, tubed, white, silky, smooth above ring, rippled and minutely furfuraceous (scurfy) below, flocculose-furfuraceous when young, densely hairy at base, and occasionally slightly expanding, but not bulbous, densely cespitose with a coarse, white, root-like mycelium. =Veil= heavy at first, mottled with yellow scales beneath; as cap expands veil becomes thin, like tissue paper, ruptures at both stem and margin leaving torn ring on stem and appendiculate fragments on edge of cap.

=Spores= shed in great quantity, rich dark umber-brown without shade of purple.

=Taste= strong like almond. =Smell= slightly of musk, like the running mycelium of A. campester.

Found at Mt. Gretna, Pa. _Charles McIlvaine._

I have never found worms in this species. It is very prolific and its habitat shows that it can be cultivated. Its freedom from worms and lasting carrying quality will make it commercially valuable.

It grew in an old roofless stable from September until after several frosts, in enormous quantity, 25 or 30 pounds in a patch. It differs from A. subrufescens in not having a shade of red about it, in its very distinct light-lilac cap when full grown, and in its snow-white youth. The young gills are pure white as are the caps. The stems sometimes taper upward, but they are usually remarkably equal.

It is delicate when cooked and of excellent flavor.

=A. tabula´ris= Pk.—relating to boards. =Pileus= 5–10 cm. broad, very thick, fleshy, firm, convex, deeply cracked in areas, whitish, flesh whitish, tinged with yellow, the areas pyramidal, truncate, the sides horizontally striate, their apices sometimes tomentose. =Lamellæ= narrow, close, free, blackish-brown when mature. =Stem= short, thick, solid. =Spores= broadly elliptical, 7.5–9µ long, 6–7.5µ broad, generally containing a single large nucleus.

In clay soil by roadsides. Craig, Colorado. August. _E. Bethel._
