Crepidotus applanatus Fr., is a larger species, shelving and often imbricated. Crepidotus fulvotomentosus Pk., is a pretty species with a tomentose cap and tawny scales, usually occurring singly. It is closely related to C. calolepis Fr.

Figure [154] is from plants of Crepidotus versutus Pk., (No. 2732 C. U. herbarium) collected on rotting wood at Freeville, N. Y., eight miles from Ithaca. The plants are represented twice natural size.

CORTINARIUS Fr.

The genus Cortinarius is chiefly distinguished from the other genera of the ochre-spored agarics by the presence of a spider-web-like (arachnoid) veil which is separate from the cuticle of the pileus, that is, superficial. The gills are powdered by the spores, that is, the spores fall away with difficulty and thus give the gills a pulverulent appearance. The plants are fleshy and decay easily. It is necessary to have plants in the young as well as the old state to properly get at the characters, and the character of the veil is only seen in young or half developed specimens. The species are to be distinguished from other ochre-spored agarics with a cobwebby veil by the fact that the veil in Cortinarius is superficial and the gills powdery. The number of species is very large, and they are difficult to determine. They mostly occur in northern countries and in the autumn or late summer; some species, however, occur during early summer. Peck, 23d Report, N. Y. State Mus., p. 105–112, describes 21 species.

Cortinarius (Inoloma) violaceus (L.) Fr. Edible.—This species is known by the violet or dark violet color which pervades all parts of the plant. The plants are 8–10 cm. high, the pileus 7–15 cm. broad, and the stem is bulbous, 6–8 mm. in thickness. The veil is single. It occurs in woods and open places during late summer and in the autumn. The flesh of the plant is also violet, and this color is imparted to the liquid when the plant is cooked. The flavor is said to be something like that of Agaricus campestris.

Cortinarius (Myxacium) collinitus (Pers.) Fr. Edible.—This is known as the smeared cortinarius because of the abundant glutinous substance with which the plant is smeared during moist or wet weather. It grows in woods. The plants are 7–10 cm. high, the cap 5–8 cm. in diameter, and the stem is 8–12 mm. in thickness. It is usually known by the smooth, even, tawny cap, the great abundance of slimy substance covering the entire plant when moist, and when dry the cracking of the gluten on the stem into annular patches.

The pileus is convex to expanded, smooth, even, glutinous when wet, shining when dry, tawny. The gills are adnate with a peculiar bluish gray tinge when young, and clay color to cinnamon when old. The spores are nearly elliptical, and 12–15 × 6–7 µ. The stem is cylindrical, even, and with patches of the cracked gluten when dry.

Cortinarius (Dermocybe) cinnamomeus (L.) Fr. Edible.—The cinnamon cortinarius is so called because of the cinnamon color of the entire plant, especially of the cap and stem. It grows in the woods during summer and autumn. It is a very pretty plant, and varies from 5–8 cm. high, the cap from 2–10 cm. broad, and the stem 4–6 mm. in thickness.

The pileus is conic, or convex, and nearly expanded, sometimes nearly plane, and again with a prominent blunt or conic umbo. Sometimes the pileus is abruptly bent downward near the margin as shown in the plants in Fig. [155], giving the appearance of a "hip-roof." The surface is smooth, silky, with innate fibrils. Sometimes there are cinnabar stains on parts of the pileus, and often there are concentric rows of scales near the margin. The flesh is light yellowish and with stains of cinnabar. The gills are adnate, slightly sinuate, and decurrent by a tooth, easily separating from the stem, rather crowded, slightly ventricose. The color of the gills varies greatly; sometimes they are the same color as the pileus, sometimes reddish brown, sometimes blood red color, etc. This latter form is a very pretty plant, and is var. semi-sanguineus Fr.
