Pileus (mycology)

“ When young, its stalk is tough, white, and solid; but as it grows this becomes hollow and presently changes to yellow; tapering below, it is effused into the substance of the pileus, which is of the same colour with it. The pileus is lobed, and irregular in shape, its margin at first deeply involute, afterwards when expanded, wavy. The veins or plaits are thick, subdistant, much sinuated, running some way down the stalk. ”

“ The pileus thin and fleshy, entirely dry, at first clothed with silky down, becoming smooth in mature plants. The gills are changeable in color. The stem is equal or tapering downward, stuffed, sometimes hollow, smooth.
V. Telamonia, meaning a bandage or lint. The pileus is moist, watery, smooth or sprinkled with whitish superficial fibres, the remnants of the web-like veil. The flesh is thin, somewhat thicker at the center. The stem is ringed and frequently scaly from the universal veil, slightly veiled at the apex, hence almost with a double veil. The plants are usually quite large. ”

“ The pileus is said to become greenish very late in the season. The stem, in the typical form, is described as sulphur-yellow in color, but with us it is more often white. The scales of the disk are sometimes wanting. In our plant the taste is slightly farinaceous at first, but it is soon unpleasant.
Var. pinastreti A. and S. is a slender form having a thin, even pileus, thinner and more narrow gills and a more slender stem. A. crassus Scop., A. aureus Schaeff., and A. flavovirens Pers. are recorded as synonyms of this species. Peck, 44th Rep. ”

“ Pileus up to 2 in. long and 1 in. broad, sessile, at first resupinate then expanded and horizontal, often lobed, upper stratum of pileus gelatinous, brown, bristling with squarrose or erect squamules. Flesh thickish. Gills radiating from the point of attachment, broad, rather distant, grayish-white.
On old trunks. Imbricated. Readily distinguished by the brown, squarrosely scaly pileus. Massee.
Spores oblong, oblique, 8×5μ Morgan.
In June, 1886, the writer found this species in oak woods near Philadelphia. It grew on fallen trunks and on decaying spots of living timber. ”

“ The pileus often rests upon its back and is attached by a point when young, but it becomes turned backward with age. The species are few and infrequent. All inhabit decaying wood.
267C. ni ́dulans Pers.—nidus, a nest. Pileus 1–3 in. broad, stemless, attached by the pileus or rarely narrowed behind into a short stem-like base, caps often overlapping one another, suborbicular or kidney-shaped, downy, somewhat pointed-hairy or scaly-hairy toward the margin, yellow or buff color, the margin at first turned inward. Lamellæ rather broad, moderately close or subdistant, orange-yellow. ”

“ The pileus is one to two inches broad, shining, satiny, adpressed fibrillose, brown-yellow, campanulate, then expanded, longitudinally cracked.
The gills are free, somewhat ventricose, at first white, brownish-clay color.
The stem is one to two inches high, distant from the pileus, solid, firm, nearly smooth, bulbous, mealy white above. Spores smooth, 10–11×6μ.
I. eutheles differs from this species in being umbonate; I. pyriodora in its strong smell. Many plants will often be found in one place in open woods or in cleared places. ”

“ In most of the species the pileus is at first resupinate, but it generally becomes reflexed as it enlarges. It is generally sessile or attached by a mass of white fibrils or tomentum. For this reason it is usually somewhat tomentose or villose about the point of attachment, even in species that are otherwise glabrous. In several species the pileus is moist or hygrophanous and then the thin margin is commonly striatulate. ”

“ The umbo had developed into a minute pileus. With us the prevailing color of the pileus is yellowish-red or cinnamon-red. Sometimes the color is almost the same as that of L. volemus and L. hygrophoroides, and again it is a tan-color or a bay-red, as in L. camphoratus, from which such specimens are scarcely separable, except by their lack of odor. In young plants the pileus usually has a moist appearance, which is sometimes retained in maturity. Cordier pronounces the species edible, and says that he has tested it several times without inconvenience. Peck, 38th Rep. ”

“ The pileus is corky, coriaceous, convex, then plane, hairy with rigid bristles, zoned with concentric furrows; of one color, whitish, sometimes these zones are quite marked as in Figure 342.
The pore surface is at first white, or whitish, becoming dark or brownish in age. The pores are round, the walls rather thick. It is found on logs and stumps in the woods. It is a very common plant and widely distributed. ”

“ Pileus 2 in. broad, fuliginous, disk date-brown, thin, ovate then bell-shaped, covered with small branny scales, then opening into furrows and flattened, undulately sulcate, disk obtuse, even. Stem 2–3 in. long, 2–3 lines thick, fistulose, slightly firm, attenuated upward, adpressedly silky, becoming even, white. Gills adnexed, at first crowded, distant when the pileus is split, linear, white then reddish, at length brownish-blackish.
A larger and more remarkable species than all the neighboring ones. ”

“ The species is related to T. columbetta, from which its larger size, constantly scaly pileus, more cespitose mode of growth, larger spores and farinaceous taste separate it. The scales of the pileus are brownish, and the pileus itself is sometimes slightly dingy on the disk. The young margin is pure white like the stem, and both it and the upper part of the stem are sometimes studded with drops of moisture.
The plant was found on trial to be edible, but not of first quality. The flesh is not very tender, nor the flavor captivating even in young specimens. ”

“ The veil is reticulate, frequently surrounding the whole of the stem from the pileus to the volva, often torn. The pileus is pitted, deliquescent, six to eight inches high, apex acute. Spores elliptic-oblong.
I am sure I never saw finer lace-work than I have seen on this plant. A few years ago one of these plants insisted upon growing near my house, where a fence post had formerly been, with the effect of almost driving the family from home. One can hardly imagine so beautiful a plant giving off such an odor. It is not a common plant in our state. ”

“ The Pileus.—By far the larger number of funguses mentioned in this work have a pileus, or cap; all such belong to the first great tribe Pileati; they include the genera Agaricus, Boletus, Cantharellus, Morchella, Hydnum, Fistulina, and [69] Polyporus, each of which furnishes its quota of alimentary species, together with many others not esculent. The form of the pileus, like that of the stalk, is various in these different genera, besides being variable in the different species of the same genus ”

“ The species grow on the ground, in spring. Massee.
V. digitalifor ́mis Pers.—digitus, a finger. Pileus at first nearly even, olivaceous-umber, dark at the apex. Stem obese, furnished at the base with a few reddish radicles, white with a slight rufous tinge, marked with transverse reddish spots; smooth to the naked eye, but under a lens clothed with fine adpressed flocci, the rupture of which gives rise to the spots, which are, in fact, minute scales. In the mature plant the pileus is 3⁄4 in. ”

“ It is the only species which is sure to respond to the methods of cultivation.
It is the same species which is bought in cans at the store.
In very young plants the pileus is somewhat globular, as will be seen in the small plants in the front row in Figure 248. The edge is connected with the stem by the veil; then round convex, then expanding, becoming almost flat; surface dry, downy, even, quite scaly, varying in color from creamy-white to a [Pg 308] light-brown; margin extending beyond the gills, as will be seen in Figure 249 in the one on the extreme right. ”

“ Pileus 11⁄2-21⁄2 in. across, subcylindrical, then oval bell-shaped, lower half of pileus usually undulate but not furrowed or striate, disk obtuse, usually depressed, distinctly scaly, dingy white, toward the apex tinged with pale brown, scales darker. Flesh very thin. Gills free, tapering toward each end, 1⁄4 in. or more broad, crowded, pale then blackish. Stem 5–8 in. long, 3⁄4 in. thick at the 372base, slightly attenuated upward, silky-white, stuffed; toward the base there is a depressed zone caused by the edge of the pileus when young. Ring fugacious. Spores elliptical, 15×7μ. ”

“ The pileus when young is broadly ovate, then becomes convex or fully expanded and flat in age, and is quite thin. The ground color is whitish, often with a yellowish tinge, while the surface is ornamented with numerous minute brownish scales which are scattered over a large part of the cap, but crowded or conjoined at the center into a large circular patch. ”

“ Wounds and bruises are apt to assume brownish-red hues. Dr. Herbst says: "This is truly an American plant, not being found in any other country. This is the pride of the family. There is nothing more beautiful than a cluster of this fungi. To look over the beautiful scaly pileus is a sight equally as fascinating as a covey of quail."
Found in grassy lawns and on old sawdust piles, in common with Pluteus cervinus. It is found almost all over the state. It is quite equal to the Parasol mushroom in flavor. It has a tendency to turn the milk or cream in which it is cooked to a reddish color. ”

“ This genus includes a great variety of species, and is distinguished from all other genera by having a fleshy pileus furnished underneath with gills, which are placed at right angles to the stem. Some species, during their infancy, are enclosed either in one or more membranes.

Old words in Natural History seldom become obsolete, but they change their meanings strangely. Were Dioscorides and Pliny redivivi, they would find nothing but misnomers! ”
