The cracks in the cap become yellow, on which account this species is called the Yellow-cracked Boletus. The taste of the flesh is sweet and agreeable. Palmer compares it with the taste of a walnut. The plant should not be feared because the flesh turns blue when bruised. I first found this species in Whinnery"s woods, Salem, Ohio. The specimens in Figure 284 grew near Chillicothe and was photographed by Dr. Kellerman.
July to August.
_Boletus chrysenteron. Fr._
THE RED-CRACKED BOLETUS. EDIBLE.
[Ill.u.s.tration: Figure 285.--Boletus chrysenteron. One-half natural size.
Caps yellowish to red. Flesh yellow.]
Chrysenteron means gold or golden within. The pileus is two to four inches broad, convex, becoming more flattened, soft to the touch, varying from light to yellowish-brown or bright brick-red, more or less fissured with red cracks; the flesh yellow, changing to blue when bruised or cut, red immediately beneath the cuticle.
The tube surface is olive-yellow, becoming bluish when bruised, tube-openings rather large, angled and unequal in size.
The stem is generally stout, straight, yellowish, and more or less streaked or spotted with the color of the cap. The spores are light brown and spindle-shaped. This species will be easily distinguished from B. subtomentosus because of its bright color and the cracks in the cap turning red, whence the name of the "Red-cracked Boletus."
The cap of this species strongly resembles Boletus alveolatus, but the latter has rose-colored spores and a red pore surface, while the former has light brown spores and an olive-yellow pore surface. Tolerton"s and Bower"s woods, Salem, Ohio, July to October.
_Boletus edulis. Bull._
THE EDIBLE BOLETUS.
[Ill.u.s.tration: Plate XLII. Figure 286.--Boletus edulis.
Pileus light brown, tubes yellowish or greenish-yellow. Stem bulbous and faintly reticulate. Natural size.]
This is quite a large and handsome plant and one rather easily recognized. The firm caps of the young plant and the white tubes with their very indistinct mouths, and the mature plants with the tubes changing to a greenish yellow with their mouths quite distinct, are enough to identify the plant at once.
The pileus is convex or nearly plane; variable in color, light brown to dark brownish-red, surface smooth but dull, cap from three to eight inches broad. The flesh is white or yellowish, not changing color on being bruised or broken.
The tube-surface is whitish in very young plants, at length becoming yellow and yellowish-green. Pore openings angled. The tubes depressed around the stem, which is stout, bulbous, often disproportionately elongated; pale-brown; straight or flexuous, generally with a fine raised net-work of pink lines near junction of cap, sometimes extending to the base. The taste is agreeable and nutty, especially when young.
Woods and open places. July and August. Common about Salem and Chillicothe, Ohio.
It is one of our best mushrooms. Captain McIlvaine says: "Carefully sliced, dried, and kept where safe from mold, it may be prepared for the table at any season."
_Boletus speciosus. Frost._
THE HANDSOME BOLETUS. EDIBLE.
[Ill.u.s.tration: Figure 287.--Boletus speciosus. Natural size. Cap red or deep scarlet. Tubes bright lemon-yellow.]
Speciosus means handsome.
The pileus is three to six inches broad, at first very thick, subglobose, compact, then softer, convex, glabrous or nearly so, red or deep scarlet. The flesh is pale yellow or bright lemon-yellow, changing to blue where wounded.
The tubes are adnate, small, subrotund, plane, or slightly depressed around the stem; bright lemon-yellow, becoming dingy-yellow with age, changing to blue where bruised.
The stem is two to four inches long, stout, subequal or bulbous, reticulated, bright lemon-yellow without and within, sometimes reddish at the base. The spores are oblong-fusiform, pale, ochraceous-brown, 10-12.54-5.
The young specimen can be recognized by the whole plant"s being of a vivid lemon-yellow except the surface of the cap. The plant quickly turns to green, then blue, wherever touched. It has a wide distribution in the Eastern and Middle states. The plant in Figure 287 was found in Haynes" Hollow by Dr. Chas. Miesse and photographed by Dr. Kellerman.
As an edible it is among the best. Found from August to October.
_Boletus cyanescens. Bull._
[Ill.u.s.tration: Figure 288.--Boletus cyanescens.]
Cyanescens is from _cyaneus_, deep blue, so called the moment you touch it, it turns a deep blue.
Pileus is two to four inches across, convex, then expanded, sometimes nearly plane, frequently wavy, covered with an appressed tomentum; opaque, pale-buff, grayish-yellow, or yellowish, flesh thick, white, quickly changing to a beautiful azure-blue where cut or wounded.
The tubes are quite free, openings small, white, then pale-yellow, round, changing color the same as the flesh.
The stem is two to three inches long, ventricose, h.o.a.ry with fine hair, stuffed at first, then becoming hollow, colored like the pileus.
The spores are subelliptical, 10-12.56-7.5.
The specimens in Figure 288 were found on rather steep wooded hillsides, Sugar Grove, Ohio. They were all solitary. I have found a few specimens about Chillicothe. They are widely distributed in the Eastern states.
Captain McIlvaine says in his book the caps make an excellent dish cooked in any way. I have never tried them. Found on hilly ground in August and September.
_Boletus indecisus. Pk._
THE UNDECIDED BOLETUS. EDIBLE.
[Ill.u.s.tration: Figure 289.--Boletus indecisus. One-half natural size.]
Indecisus means undecided; so called because it favors very closely Boletus felleus. There is a difference in the style of the two plants by which, after continued tasting, the student can readily separate them.
The pileus is three to four inches broad, dry, slightly downy, convex, ochraceous-brown, plane, often irregular on the margin, sometimes wavy, flesh white, and unchangeable, taste mild or sweet.
The tube surface is nearly plane and firmly set against the stem, grayish, becoming tinged with flesh color in age, changing to a brown when bruised; the mouths small and nearly round. The stem is covered with a fine mealy substance, straight or flexuous, sometimes reticulated above. The spores are oblong, brownish flesh color, 12.5-154.
The B. indecisus can be readily told from B. felleus by its sweet taste and brownish spores. It is my favorite of all the Boleti, indeed I think it equals the best of mushrooms. Its favorite habitat is under beech trees in the open. It is widely distributed from Ma.s.sachusetts to the west. Found in July and August.
_Boletus edulis. Bull.--Var. clavipes. Pk._
CLUB-FOOTED BOLETUS. EDIBLE.
[Ill.u.s.tration: Figure 290.--Boletus edulis, var. clavipes. Two-thirds natural size. Note confluent caps on right.]
Clavipes means club-footed. Pileus fleshy, convex, glabrous, grayish-red or chestnut-color. Flesh white, unchangeable. The tubes at first concave or nearly plane, white and stuffed, then convex, slightly depressed around the stem, ochraceous-yellow. Stem mostly obclavate, inversely club-shaped, and reticulate to the base. The spores oblong-fusiform, 12-154-5. _Peck._ 51st Rep.
The club-footed Boletus is very closely related to B. edulis. It differs, perhaps, in a more uniform color of the cap, and in having tubes less depressed around the stem, and less tinted with green when mature. The stem is more club-shaped and more completely reticulated.
