Gomphidius viscidus.
One-half natural size.

G. vis´cidus Fr.—viscid. Pileus 2–3 in. and more broad, brownish-red, compact, at first bell-shaped, then expanded, umbonate, slightly viscous, shining when dry. Flesh yellowish. Stem 3–4 in. and more long, ½ in. thick, solid, equal or attenuated at the base which is rhubarb-colored internally, scaly-fibrillose, not very viscous, yellowish. Cortina very evidently floccose, not glutinous, woven in the form of a ring, but readily falling off. Gills deeply decurrent, distant, the shorter ones adnexed to the longer, not truly branched, at first paler, somewhat olive, at length brownish-purple, clouded with the spores. Fries.

Hymenophore descending between the gill plates. Odor not unpleasant. Stevenson.

Chiefly used in catsup. Cooke. Edible. Leuba. Cooke.

North Carolina, Massachusetts, Frost. Minnesota, California, Pennsylvania.

Many grew under pines at Mt. Gretna, Pa., September to November. The gills seemed branched, but were grown together. Taste and smell pleasant. The caps are good, but not equal to G. rhodoxanthus.

G. rhodoxan´thus Schw. (Plate XCVII, fig. 4, 5, p. 352.) Solitary. Pileus 1–2 in. broad, cushion-shaped, reddish-yellow, sometimes with dusky hues. Gills arched, decurrent, orange-yellow. Stem attenuated, short, firm.

Spores oblong, 10–12.5µ in length. Peck. Olivaceous. McIlvaine.

Solitary, gregarious or cespitose.

Among leaves and grass in shady places. August to October.

When the student has mastered the name and memorized the description, Gomphidius rhodoxanthus can not be mistaken for any other species.

It is not common in localities I have frequented, but its presence is pretty general in the United States, specimens having been sent to me from Georgia, Iowa, New York, New Jersey, etc., and I have found it in West Virginia, North Carolina, Woodland Cemetery, Philadelphia, and other places in Pennsylvania, from July to September, 1898, inclusive. Having enjoyed it in West Virginia in 1882, I was delighted to find it in generous quantity at Mt. Gretna, Pa., and to eat many meals of it. Its caps are not excelled by any edible fungus. They have solid, delicious substance and rich full flavor.

The plant is often cespitose. I have never found its cap viscid or glutinous. The cooked flesh has the latter consistency.

MONTAGNITES Fr.
After Montagne. (Plate CI, fig. 6, p. 368.)

The universal veil forming a volva, persistent. Stem dilated at the apex into a plane round disk, even on both sides, to the margin of which are adfixed the gills which are free, not joined by any membrane, radiating, razor-shaped, persistent, obtuse at the edge. Trama cellulose. Spores oblong, even, black fuscous. Fries.

A single species is reported from Texas.

FAMILY II.—POLYPORACEÆ.

Hymenophore inferior, facing the ground. Hymenium consisting of tubes with poriform mouths which are round or angular, sometimes sinuous or torn, lined with 4-spored sporophores and cystidia.

Fleshy, coriaceous or woody fungi, most abundant and luxuriant in warm countries. Intermediate between the Agaricaceæ and the Hydnaceæ, connected with the former by Dædalea and Lenzites, and with the latter by Fistulina and Irpex. Fries.

Within this large family are famed edible species, notably in Boletinus, Boletus and Fistulina. In the woody species the razor-strop man finds material for his strops (Polyporus celulinus); the surgeon styptics; the peasant punk to catch sparks from his flint, and the 4th of July urchin a fire-holder to light his pyrotechnics. The Chinese have placed some species in their fathomless materia medica, while the Polyporus of the locust tree is used in America as a medicine for horses. No fungoid growth is more universal. They are the ever active pruners of our trees and converters of forest debris. They begin the task in Nature’s laboratory of changing decaying wood into assimilable shape as food to feed the very trees that dropped it. Some are of annual growth, others add to their substance year after year, often attaining enormous size. In summer and in winter they are ever present objects for interesting study.

SYNOPSIS OF GENERA.
Boletinus. Page 398.

Hymenium composed of broader radiating gills connected by very numerous more narrow anastomosing branches or partitions and forming large angular pores. Tubes somewhat tenacious, not easily separable from the hymenophore and from each other, adnate or subdecurrent, yellowish. Peck.

Boletus. Page 404.

Stratum of tubes easily separable from the hymenophore. Stem central.

Tubes like Boletus, but pileus with large scales. Stem central.

Fistulina. Page 477.

Fleshy, lateral, tubes crowded but distinct.

Polyporus. Page 479.

Stratum of tubes distinct from hymenophore, but not separable, not stratose; fleshy and tough, stipitate or sessile.

Fomes.

Tubes as in Polyporus, often stratose; woody, sessile; dimidiate. (No edible species reported.)

Tubes as in Polyporus, not stratose, generally developing from the center to the margin, at first shallow and punctiform, coriaceous or membranaceous. (No edible species reported.)

Poria.

Tubes as in Polyporus, not stratose; entirely resupinate. (No edible species reported.)

Mucronoporus.

Tubes studded with reddish-brown spines, intermingled with the basidia, otherwise as in Polystictus (and also as in Polyporus and Fomes). Atkinson. (No edible species reported.)

BOLETI´NUS Kalchb.

(Plate CXIII, p. 402.)

Hymenophore not even (as in Boletus), but extended in blunt points descending like a trama among the tubes. Tubes not easily separable from the hymenophore and from each other. Stem ringed, hollow. Spores pale yellowish. Sylloge, Vol. VI, p. 51.

Professor Peck has for excellent reasons, given in his Boleti of the United States, emended the generic diagnosis of Fries thus: Hymenium composed of broader radiating lamellæ connected by very numerous more narrow anastomosing branches or partitions and forming large angular pores. Tubes somewhat tenacious, not easily separable from the hymenophore and from each other, adnate or subdecurrent, yellowish.

Professor Peck classifies Boletinus as follows:

Stem hollow B. cavipes
Stem solid 1
1. Stem lateral or eccentric B. porosus
1. Stem central 2
2. Pileus pale yellow, silky B. decipiens
2. Pileus red or adorned with red scales 3
3. Pileus red B. paluster
3. Pileus soon red-squamose B. pictus
Boleti of the United States, p. 76.

There are six species given as found in the United States—B. cavipes Kalchb., B. pictus Pk., B. paluster Pk., B. decipiens Pk., B. porosus Pk., B. appendiculatus Pk.—of these I have found and eaten four. B. decipiens has, at this writing, not been seen by Professor Peck, but Professor Farlow, of Harvard, has informed him of authentic specimens. There is every probability of its being as edible as the others; a description of it is, therefore, given.

In consistency Boletinus is of the best, being rather like that of marshmallows, and the same as Boletus subaureus. The flavor is mild and pleasant.

Professor Peck mentions that the smell of B. porosus is sometimes unpleasant. I have been fortunate in not having had this experience.

B. ca´vipes Kalchb. Pileus broadly convex, rather tough, flexible, soft, subumbonate, fibrillose-scaly, tawny-brown, sometimes tinged with reddish or purplish. Flesh yellowish. Tubes slightly decurrent, at first pale-yellow, then darker and tinged with green, becoming dingy-ochraceous with age. Stem equal or slightly tapering upward, somewhat fibrillose or floccose, slightly ringed, hollow, tawny-brown or yellowish-brown, yellowish at the top and marked by the decurrent dissepiments of the tubes, white within. Veil whitish, partly adhering to the margin of the pileus, soon disappearing. Spores 8–10×4µ.

Pileus 1.5–4 in. broad. Stem 1.5–3 in. long, 3–6 lines thick. Swamps and damp mossy ground under or near tamarack trees. New York, Peck; New England, Frost.

The pileus is clothed with a fibrillose tomentum which becomes more or less united into floccose tufts or scales. The umbo is not always present and is generally small. The young stem may sometimes be stuffed, but, if so, it soon becomes hollow, though the cavity is irregular. The freshly shed spores have a greenish-yellow or olivaceous hue, but in time they assume a pale or yellowish-ochraceous hue. This species is apparently northern in its range. It loves cold sphagnous swamps in mountainous regions. Peck, Boleti of the U.S.

West Virginia mountains under spruce trees. Haddonfield, N.J., among scrub pines. Mt. Gretna, Pa., among pines.

It is of excellent consistency and of mild pleasant flavor. It is at its best in patties, croquettes and escallops.

B. appendicula´tus Pk. Pileus fleshy, convex, glabrous, ochraceous-yellow, the margin appendiculate with an incurved membranous veil. Flesh pale-yellow, unchangeable. Tubes rather small, yellow, their mouths angular, unequal, becoming darker or brownish where wounded. Stem solid, slightly thickened at the base, yellow. Spores pale-yellow, oblong, 10–12×4µ. Pileus 4–8 in. broad. Stem 2–3 in. long, 4–6 lines thick.

Under or near fir trees. Washington. September to December. Yeomans. Peck, Bull. Torrey Bot. Club, Vol. 23, No. 10.

B. pic´tus Pk. Pileus convex or nearly plane, at first covered with a red fibrillose tomentum which soon divides into small scales revealing the yellow color of the pileus beneath. Flesh yellow, often slowly changing to dull pinkish or reddish tints where wounded. Tubes tenacious, at first pale yellow, becoming darker or dingy ochraceous with age, sometimes changing to pinkish-brown where bruised, concealed in the young plant by the copious whitish webby veil. Stem equal or nearly so, solid, slightly and somewhat evanescently annulate, clothed and colored like or a little paler than the pileus, yellowish at the top. Spores ochraceous, 9–11×4–5µ.

Pileus 2–4 in. broad. Stem 1.5–3 in. long, 3–6 lines thick.

Woods and mossy swamps. New York, Peck; New England, Frost; North Carolina, Curtis. Peck, Boleti of the U.S.

West Virginia mountains, 1882. Haddonfield, N.J., Angora, West Philadelphia, Mt. Gretna, Pa. August and September. In mixed woods, principally oak. Leominster, Mass. C.F. Nixon, Ph. G.

It is sometimes found upon much decayed chestnut stumps.

The caps of some species are so cracked as to appear distinctly areolate. The white webby veil is often persistent. The fungus is one of the handsomest. Its rich variegated colors impress it upon eye-memory. It is one of the very best edible species.

(Plate CXIIa.)

Boletinus paluster.
Natural size. (After Peck.)

B. palus´ter Pk.—Pileus thin, broadly convex, plane or slightly depressed, sometimes with a small umbo, floccose-tomentose, bright red. Tubes very large, slightly decurrent, yellow, becoming ochraceous or dingy ochraceous. Stem slender, solid, subglabrous, red, yellowish at the top. Spores pinkish-brown, 8–9×4µ.

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

Wet places and sphagnous mossy swamps. New York, Peck. Maine, Harvey. Peck, Boleti of the U.S.

Angora, West Philadelphia and Mt. Gretna, Pa. September. McIlvaine.

A few specimens found at Mt. Gretna had stems slightly reticulated. Its taste is sweet, smell mild, and cooked it is of excellent body and flavor.

B. deci´piens (B. and C.) Pk. Pileus dry, minutely silky, whitish-yellow or pale-buff, flesh buff, one-third in. thick; hymenium plane or somewhat concave, yellow, consisting of large, unequal, flexuous radiating tubes resembling multiseptate lamellæ. Stem equal, solid but spongy. Veil floccose, evanescent, adhering for a time to the margin of the pileus. Spores rather minute, oblong, ochraceo-ferruginous (rusty yellow), 8–10×3.5–4µ.

Pileus 2 in. broad. Stem 2–2.5 in. long, 3–4 lines thick.

Thin woods. North and South Carolina. M.A. Curtis.

Specimens of this species have not been seen by me. The authors remark that its affinities are clearly with Boletinus flavidus and its allies, from which it is distinguished by its large radiating pores. They also say that when dry it is scarcely distinguishable from Paxillus porosus Berk., except by its spores. This would imply that its stem is eccentric or lateral, and I have been informed by Mr. Ravenel that it is sometimes so. But specimens of this kind, labeled Boletinus decipiens B. and C., have been received, which show by their spores that they are Paxillus porosus. Besides, Professor Farlow informs me that authentic specimens of B. decipiens in the Curtisian Herbarium have only central stems, from which things I suspect that the two species have been confused. The spore dimensions here given are derived from a specimen in the Curtis Herbarium, through the kindness of Professor Farlow. Peck, Boleti of the U.S.

I have not recognized this Boletinus. Its affinities are with excellent edible species.

Photographed by Dr. J.R. Weist.           Plate CXIII.
BOLETINUS POROSUS.

B. poro´sus (Berk.) Pk. (Plate CXIII.) Pileus fleshy, viscid when moist, shining, reddish-brown. Flesh 3–9 lines thick, the margin thin and even; hymenium porous, yellow, formed by radiating lamellæ a line to half a line distant, branching and connected by numerous irregular veins of less prominence and forming large angular pores. Stem lateral, tough, diffused into the pileus, reticulated at the top by the decurrent walls of the tubes, colored like the pileus. Spores semi-ovate.

Pileus 2–5 in. broad. Stem 6–16 lines long, 4–6 lines thick.

Var. opa´cus (Paxillus porosus Berk., Bull. N.Y. State Mus. 2, p. 32). Pileus dry, glabrous or subtomentose, not shining, brown or tawny-brown. Spores brownish-ochraceous, 9–11×6–8µ.

Damp ground in woods and open places. Ohio, Lea, Morgan; North Carolina, Curtis; New England, Frost, Farlow; Wisconsin, Bundy; New York, Peck.

This species is remarkable for its lateral or eccentric stem. There is often an emargination in the pileus on the side of the stem which gives it a kidney shape. In the typical form it is described as viscid when moist, and the Wisconsin plant is also described as viscid, but in all the New York specimens that I have seen it is dry and sometimes minutely tomentose. I have, therefore, separated these as a variety. The color of the pileus varies from yellowish-brown to reddish-brown or umber. A disagreeable odor is sometimes present. The tubes are rather short and tough and do not easily separate from the hymenophore and from each other. In the young plant they are not separable. They sometimes become slightly blue where wounded. As in other species they are pale yellow when young, but become darker or dingy-ochraceous with age. The spores have been described as bright yellow, but I do not find them so in the New York plant. The plant is incongruous among the Paxilli by reason of its wholly porous hymenium, but in this place it seems to be among its true allies. Peck, Boleti of the U.S.

Fine specimens were sent to me by Mr. H.I. Miller, Terre Haute, and Dr. J.R. Weist, Richmond, Ind. They were in condition to be eaten and enjoyed. No disagreeable odor was perceptible.

B. borea´lis Pk. Pileus fleshy, convex, obtuse or subumbonate, brownish-yellow, obscurely and somewhat reticulately streaked with reddish-brown lines. Pores large, angular, unequal, slightly decurrent, brownish-yellow. Stem short, equal or slightly tapering upward, brownish-yellow with a whitish myceloid tomentum at the base. Spores oblong, 10–12.5×4–5µ.

Pileus 1–2 in. broad. Stem about 1 in. long.

Sandy soil. Capstan Island, Labrador. October. Waghorne.

The markings of the pileus appear as if due to the drying of a glutinous substance. The radiating lamellæ and the transverse partitions of the interspaces are very plainly shown. Described from two dried specimens. Peck, Bull. Torr. Bot. Club, Vol. 22, No. 5.

BOLE´TUS Dill.

Gr—a clod.

The name of a fungus considered a great delicacy among the Romans, derived from bolos, a clod, probably to denote the round figure of the plant.

Hymenium wholly composed of small tubes, connected together in a stratum, the surface of which is dotted with their poriform mouths, and which is distinct from the hymenophore on account of the latter not descending into a trama. Tubes packed close together, easily separating from the hymenophore and from one another. Pores or mouths of the tubes round or angular (in the subgenus Gyrodon sinuous or gyroso-plicate). Spores normally fusiform, rarely oval or somewhat round. Growing on the ground, fleshy, putrescent, with central stems. Mostly edible, and of importance as articles of food; a few poisonous. Fries.

No American species in Gyrodon. It is therefore omitted in synopsis of tribes. C.M.

This genus abounds in species and is related to Boletinus on one hand and to Polyporus on the other. From the latter it is distinguished by the absence of a trama and from both by the tubes being easily separable from the hymenophore and from each other. Some of the species are very variable, others are so closely allied that they appear to almost run together.

The species are generally terrestrial, but B. hemichrysus is habitually wood-growing, and others are occasionally so.

The spores vary so much in color in such closely related species that this character is scarcely available for general classification, but it is valuable as a specific character and should always be noted.

Peck, Boleti of the U.S.

C.H. Peck, N.Y. State Botanist, has contributed to Mycological literature his careful arrangement and analysis of species of this genus, in his “Boleti of the United States.” Species of the genus are found in every state of the Union. Several species are common to all the states. Comprehending, as do the states, all sorts of climates within their vast range of latitude, differences in appearance and structure in the same species must be expected, dependent largely, as they are in most fungi, upon habitat and environment. These variations will frequently suggest new species. Descriptions which are typical and which can be recognized as standard are most desirable. Professor Peck’s are accepted by the writer as such, that there may be uniformity, and are quoted as fully as space will permit. Such variations as are attributable to locality will be noted.

Since 1882 the writer has given great attention to the edible qualities of the Boleti. He is convinced by many personal tests and those made by his family and friends, that much, if not all, of the suspicion thrown about Boleti is unjust and erroneous. He is able to state positively that change of color when bruised or broken; bitter and pepperiness have nothing whatever to do with the edible qualities of species exhibiting them, excepting in B. felleus, which exhibits an intense bitter, not lost in cooking. It is not poisonous.

The writer has the courage of his convictions, and has taken interest in eating species with a bad reputation whenever opportunity afforded, that their just dues might be given them. He has never experienced the slightest inconvenience. But others may not be so fortunate.

Before cooking Boleti the stem, unless crisp and tender, should be removed, as should the tubes unless young and fresh. They broil, fry, stew, make good soups and dry well. See recipes.

It is believed that all species of Boleti up to this time found in America are described in this volume. When no remarks of the writer follow the descriptions, he has not had an opportunity to test the edible quality of the species.

Viscipellesviscum, bird lime; pellís, a skin.

Pileus covered with a viscose pellicle. Stem solid, neither bulbous, lacerated nor reticulated with veins. Tubes adnate, rarely sinuate, of one color.

The first four and several of the final species here described recede somewhat from the character of the central or typical species of the group.

(Plate CXV.)

Boletus spectabilis.
Natural size.

B. specta´bilis Pk.—spectabilis, distinguished. Pileus broadly convex, at first covered with a red tomentum, then scaly, viscid when moist, red, the tomentose scales becoming grayish-red, brownish or yellowish. Flesh whitish or pale-yellow. Tubes at first yellow and concealed by a reddish glutinous membrane, then ochraceous, convex, large, angular, adnate. Stem nearly equal, annulate, yellow above the annulus, red or red with yellow stains below. Spores purplish-brown, 13–15×6–7µ.

Pileus 2–5 in. broad. Stem 3–5 in. long, 4–6 lines thick.

Thin woods in swamps. New York, Peck; Wisconsin, Bundy.

This is a rare and showy species which inhabits the cold northern swamps of the country. It probably extends into Canada. When cut, the flesh emits a strong, unpleasant odor. Wounds of the flesh made by insects or other small animals have a bright-yellow color. When young, the tomentose veil covers the whole plant, but it soon parts into scales on the pileus and partly or wholly disappears from the stem. Peck, Boleti of the U.S.

London, Can., J. Dearness; Peck, Rep. 44, N.Y. State Bot.

B. Elben´sis Pk. Pileus convex, glabrous, viscid when moist, dingy gray or pinkish-gray inclining to brownish, obscurely spotted or streaked as if with patches of innate fibrils. Flesh white. Tubes at first whitish, becoming dingy or brownish-ochraceous, nearly plane, adnate or slightly decurrent, rather large, angular. Stem nearly equal, annulate, whitish above the ring, colored like the pileus below, sometimes slightly reticulated at the top. Spores ferruginous-brown, 10–12×4–5µ.

Pileus 2–4 in. broad. Stem 3–5 in. long, 4–6 lines thick. Thin woods of tamarack, spruce and balsam. New York. Peck.

Its locality is thus far limited to the Adirondack region of this state. Peck, Boleti of the U.S.

B. sero´tinus Frost.—late. Bulletin Buffalo Soc. Nat. Sci., 1874. Pileus flat or convex, viscid, sordid brown, streaked with the remnants of the veil, especially near the margin, which is white, very thin, and when partly grown singularly pendent. Flesh white, changing to bluish. Tubes large, angular, unequal, slightly decurrent, at first sordid white or gray, sometimes tinged with green near the stem, afterward cinnamon-yellow. Stem reticulated above the ring which adheres partly to it and partly to the margin of the pileus, white but stained by the brownish spores and tinged with yellow at maturity. Spores 10×6µ.

Shaded grassy ground. New England, Frost.

Probably this is only a variety of the preceding species. Peck, Boleti of the U.S.

B. salmoni´color Frost. Bull. Buff. Soc. Nat. Sci., 1874. Pileus convex, soft, very glutinous, brownish or tawny-white with a faint tinge of red, wine-color when dry, the margin thin. Flesh tinged with red. Tubes simple, even, angular, adnate, pale salmon color. Stem small, dotted above with bright ferruginous red, sordid below, annulus dingy salmon-color. Spores 8×2.5µ.

Borders of pine woods. New England. Frost.

Apparently a distinct species. No specimens seen. Peck, Boleti of the U.S.

B. el´egans Schum. Pileus convex or plane, viscose, golden-yellow or somewhat rust-color. Flesh pale-yellow. Tubes decurrent, golden or sulphur-yellow, the mouths minute, simple. Stem unequal, firm, golden or reddish, dotted above the fugacious white or pale-yellowish annulus.

Pileus 3–4.5 in. broad. Stem 2–4 in. long.

Woods, especially under or near larch trees. North Carolina, Curtis; Wisconsin, Bundy; Minnesota, Johnson. Peck, Boleti of the U.S.

Cordier and Gillet give the species as edible though not delicate.

West Philadelphia on lawns under larches, 1887–1891. McIlvaine.

The caps are of good flavor and consistency. They are best fried or broiled.

B. Clin´tonianus Pk. Pileus convex, very viscid or glutinous, glabrous, soft, shining, golden-yellow, reddish yellow or chestnut color, the margin thin. Flesh pale yellow, becoming less bright or dingy on exposure to the air. Tubes nearly plane, adnate or subdecurrent, small, angular or subrotund, pale-yellow, becoming dingy-ochraceous with age, changing to brown or purplish-brown where bruised. Stem equal or slightly thickened toward the base, straight or flexuous, yellow at the top, reddish or reddish-brown below the annulus, sometimes varied with yellow stains, the annulus white or yellow, persistent, forming a thick band about the stem. Spores brownish-ochraceous, 10–11×4–5µ.

Pileus 2–5 in. broad. Stem 2–5 in. long, 4–9 lines thick.

Mossy or grassy ground in woods or open places, especially under or near tamarack trees. New York, Peck; New England, Frost.

This is apparently closely related to B. elegans, from which it differs in its thick persistent ring, in its stem which is not at all dotted and in its longer and darker-colored spores. Its smaller tubes and persistent ring separate it also from B. flavus. In the typical form the pileus is bay-red or chestnut color, but plants growing in open places generally have it yellowish or reddish-yellow. It is mild to the taste and I have eaten it sparingly. It sometimes grows in tufts. Peck, Boleti of the U.S.

B. inflex´us Pk.—curving. Pileus convex, glabrous, viscid, yellow, often red or reddish on the disk, the margin thin, inflexed, concealing the marginal tubes. Flesh whitish, not changing color where wounded. Tubes rather long, adnate, yellowish, becoming dingy-yellow with age, the mouths small, dotted with reddish glandules. Stem rather slender, not ringed, solid, viscid, dotted with livid-yellow glandules. Spores yellowish, 10–12×4–5µ.

Pileus about 1 in. broad. Stem about 2 in. long, 2–4 lines thick.

Open woods. Trexlertown. September. Herbst.

This Boletus belongs to the tribe Viscipelles. It is remarkable for and easily recognized by the inflexed margin of the pileus, which imitates to some extent the appendiculate veil of Boletus versipellis. It sometimes grows in tufts. The paper in which fresh specimens were wrapped was stained yellow. Boletus Braunii Bres. has an inflexed margin, but that is a much larger plant with a yellowish-brown pileus, a fibrillose stem and much smaller spores. Peck, Bull. Torr. Bot. Club, Vol. 22, No. 5.

B. fla´vus With. Pileus convex, compact, covered with a brownish separating gluten, pale-yellow. Flesh pale-yellow. Tubes large, angular, adnate, yellow. Stem yellow, becoming brownish, reticulated above the membranous fugacious dirty yellowish annulus. Spores 8–10×3–4µ.

Pileus 2–5 in. broad. Stem 2–3 in. long, 6–10 lines thick.

Woods. Minnesota, Johnson; Wisconsin, Bundy.

This is apparently a rare species in this country. I have not seen it. It is said to resemble B. luteus, from which it is separated by the large angular mouths of the tubes. In British Fungi the spores are described as “spindle-shaped, yellowish-brown;” in Sylloge, as “ovoid-oblong, acute at the base, granulose, pale ochraceous.” Peck, Boleti of the U.S.

B. fistulo´sus Pk. Pileus convex, viscid, glabrous, yellow, the margin at first incurved or involute. Flesh yellow. Tubes plane or subventricose, medium size, round with thin walls, adnate or sometimes depressed around the stem, yellow. Stem rather slender, subequal, viscid, glabrous, hollow, yellow, with a white mycelioid tomentum at the base. Spores elliptical, 13×6µ.

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

Grassy woods. Auburn, Ala. July. Underwood.

A small but pretty species of a yellow color throughout. It is remarkable for its hollow stem, which is suggestive of the specific name. It is referable to the tribe Viscipelles. Peck, Bull. Torrey Bot. Club, Vol. 24, No. 3.

B. sphæros´porus Pk.—globose-spored. (Bulletin Torrey Botanical Club, Vol. XII.) Pileus at first hemispherical, then convex, glabrous, viscid, creamy-yellow, becoming reddish-brown or chestnut color with age. Flesh pale yellowish-brown. Tubes adnate or slightly decurrent, large, angular, pale-yellow, becoming brown, sometimes tinged with green. Stem stout, equal, even or slightly reticulated at the top, the membranous annulus persistent, sometimes partly adhering to the margin of the pileus. Spores globose or broadly elliptical, 8–9µ long.

Pileus 3–8 in. broad. Stem 1–3 in. long, 6–12 lines thick.

Low ravines and sandy places. Wisconsin, Trelease; Iowa, McBride.

The spores easily serve to distinguish this species from its allies. The European B. sphærocephalus has ovoid spores, but its tube mouths are minute and rotund and its stem is densely squamose. Peck, Boleti of the U.S.

B. lu´teus L.—yellow. Pileus gibbous or convex, covered with a brownish separating gluten, becoming yellowish-brown and virgate-spotted. Flesh white. Tubes adnate, minute, simple, yellow, becoming darker with age. Stem stout, yellowish and dotted above the large membranous brownish-white annulus, brownish-white or yellowish below. Spores fusiform, yellowish-brown, 6–7×3–4µ.

Pileus 2–5 in. broad. Stem 1–2 in. long, 6–10 lines thick.

Pine woods and groves. New York, Peck.

B. luteus has an international reputation for edibility. I have found it at Waretown and Haddonfield, N.J.; in Bartram’s Garden, West Philadelphia, always under pines. At Waretown it was gregarious. Pine needles, sand, anything through which it grows, adheres to the glutinous cap. It must be carefully cleaned before cooking. It is then of choice consistency and good flavor.
