Part 42

The genus Cortinarius has been divided by some authors into the following six groups: (1) Phlegmacium, in which the cap is fleshy and viscid, the veil partial, and the stem firm and dry; (2) Myxacium, in which the veil is universal and glutinous, hence the cap and stem both viscid; cap thin and the gills adnate or decurrent; (3) Inoloma, in which the cap is fleshy, dry, and at first silky with innate fibrils; veil simple and stem slightly bulbous; (4) Dermocybe, in which the pileus is thinly fleshy, dry, and at first downy, becoming smooth; the veil single and fibrillose; flesh watery, colored when moist, stem equal or attenuated downwards; (5) Telamonia, in which the cap is moist, at first smooth or dotted with the superficial fragments of the veil, the stem ringed below, or peronately scaly from the remains of the universal veil; (6) Hydrocybe, in which the cap is thin and moist, not viscid, smooth, or covered with superficial white fibrils; stem rigid, not scaly, veil thin, occasionally collapsed in an irregular ring. These subdivisions have been designated as tribes by some botanists and subgenera by others, etc. To the divisions Inoloma and Phlegmacium, respectively, belong the two species illustrated in Plate XII.

PLATE XII.

FIGS. 1 to 4.--=Cortinarius (Inoloma) violaceus= Fr. "Violet Cortinarius."

EDIBLE.

Cap fleshy, at first convex, then nearly plane, dotted with hairy tufts or scales, margin at first involute, color purple or dark violet, flesh soft, purplish; gills distant, broad, adnate, somewhat rounded near the stem, at first purplish violet, changing to an ochraceous or brownish cinnamon color as the plant matures; stem solid, somewhat bulbous at the base, purple; cortina or veil white or tinged with violet, sometimes bluish.

This is a handsome species, and though it is somewhat rare in many localities, its pretty and unusual coloring does not allow it to be easily overlooked. It is edible, and has a mushroomy taste when raw. Agaricus nudus Bull, a purple species with white spores, is sometimes confounded with it. There are other purple species of Cortinarius not so pleasant to the taste, which bear some resemblance to C. violaceus. The specimens figured in Plate XII were gathered near Dedham, Mass., on open ground on the border of a stretch of pine woods.

FIGS. 5 TO 7.--=Cortinarius (Phlegmacium) caerulescens=.

EDIBLE.

Cap fleshy, at first convex, then plane, surface even, viscid; color bluish or violet; gills adnexed and crowded, at first bluish, changing to violet or purplish hues; stem solid, short, and thick, with a broadly bulbous base, same color as the cap; veil filmy, single. In woods and on the borders of woods. This mushroom varies in color, the bluish or purplish tints being quite susceptible to atmospheric changes. When growing in the shade or well-sheltered places, it is much darker in hue than when exposed unsheltered to the bright sunlight. The specimen figured in Plate XII was gathered on low ground near a pine grove in Essex County, Mass.

Cortinarius (Phlegmacium) purpurascens Fr. bears a slight resemblance to caerulescens, but can be distinguished from it by the spotted or zoned character of the cap and the broadly emarginate gills.

Cortinarius turmalis, an edible autumnal species, having an ochraceous or brownish-yellow cap with emarginate or decurrent gills, the latter at first whitish, then reddish clay color, is found in abundance in some parts of Maryland. The gills are never tinged with purple or blue. The flesh is white. The plants are easily discovered by those familiar with their habitat, as they grow under pine needles in groups, forming small mounds extending over large spaces, and in these hiding places, in the autumnal months, they are free from insects and dust. I have collected a bushel of them in less than an hour in fresh condition in October. Some of the French authors do not class this species as edible. Gillet, in his Hymenomycetes of France, enumerates fifty-three edible species of Cortinarius, but places turmalis among the suspects. I find this mushroom not only edible, but very valuable, because of its abundance in the localities where found. It is often densely caespitose. The plant, when mature, is from 3 to 5 inches high.

C. sebaeceus, found also in pine woods, is recorded as edible. The plant is tall, white-stemmed, with broad tan-colored, somewhat viscid cap; emarginate gills, clay color at first, at last cinnamon color; stem solid, stout, fibrillose, and equal.

Cortinarius collinitus, Smeared Cortinarius, and Cortinarius cinnamomeus, with its variety semi-sanguinea, have also been tested, and found edible. The first of these is somewhat common. The plants when fresh are covered with a glutinous substance, and this should be removed before cooking. Cap smooth under the glutinous coat, light brown or tawny yellow in color, flesh white; gills whitish or light gray when young, cinnamon-hued in the matured plant. Stem solid, nearly equal, cylindrical, yellowish, and somewhat scaly. C. cinnamomeus belongs to the division Dermocybe. The cap is thin at first, silky with innate fibrids, becoming smooth, and varies from light brown to a dark cinnamon color. The gills are yellowish, then cinnamon; stem downy or silky, yellow. The variety semi-sanguinea has the lamellae red, almost as in the preceding species.

C. (Phlegmacium) varius, "Variable Cortinarius," edible, has a compact fleshy viscid, even cap, brownish in color, gills at first violet, changing to cinnamon, stout solid stem, white or whitish, adorned with adpressed flocci, flesh white.

Cortinarius (Telamonia) armillatus Fries is given in M. C. Cooke's list of edible Cortinarii. Cap fleshy but not thick, fibrillose and slightly scaly, bright bay color, thin uneven margin; stem solid, dingy, rufescent, showing irregular red zones or bands elongated and slightly bulbous at the base; gills distant, broad, pallid in color at first, changing to dark cinnamon. C. (Telamonia) haematochelis Bull. (edible), somewhat resembles the former in color and size, though not so bright a brown. Cap thin, silky-fibrillose; gills adnate, narrow and crowded, light cinnamon; stem long, solid, dingy, with a reddish zone.

C. (Hydrocybe) castaneus Bull., Chestnut Cortinarius (edible), is found in woods and gardens. The plants of this species are usually small. Cap at first campanulate, expanding, sometimes slightly umbonate in the centre, chestnut color; gills ventricose, crowded, purplish, changing to rust color; stem short, hollow or stuffed, cartilaginous, equal, pallid, reddish brown, or tinged with violet; veil white.

Subgenus Collybia Fries. Cap at first convex, then expanded, not depressed, with an involute margin; gills reaching the stem, but not decurrent, sometimes emarginate; stem hollow, with cartilaginous bark of a different substance from the hymenophore, but confluent with it; often swollen and splitting in the middle; spores white. The plants are usually found growing upon dead tree stumps; some grow upon the ground; a few are parasitic on other fungi or springing from sclerotia, small impacted masses of mycelium. The species are generally small and firm and of slow growth. A few are edible, some few have an unpleasant odor. On account of the cartilaginous stem and the dryness of their substance, some of the smaller species are apt to be taken for Marasmii. Note: Saccardo in his Sylloge gives Collybia generic rank.

PLATE XIII.

FIGS. 1 to 3.--=Ag. (Collybia) fusipes= Bull. "Spindle-Foot Collybia."

EDIBLE.

Cap fleshy, somewhat tough, convex, then plane, smooth, even or slightly cracked in places, umbo evanescent, reddish brown; gills adnexed, nearly free, broad, distant, at length separating near the stem, firm, white, changing to fawn color, or pale brown often spotted; stem long, stuffed, then hollow, externally cartilaginous, contorted, swollen in the middle, cracking in longitudinal slits, fusiform, tapering narrowly to a rooted base, reddish brown. On stumps in woods in the autumn. Cap 1 to 2 inches broad; stem 2 to 6 inches long. This species is densely caespitose. It is very generally recorded among authors as edible, although the flesh is somewhat tough. It requires long and slow cooking. An English author recommends it for pickling. Only the caps should be used for this purpose.

FIGS. 4 to 6.--=Ag. (Collybia) maculatus= A. & S. (=Collybia maculata=). "Spotted White Collybia."

Cap fleshy and compact, convexo-plane, obtuse, smooth, even, margin thin, at first involute, turned inwards, white; stem long and stout, externally cartilaginous, ventricose, sometimes striate, tapering towards the base; gills free, or nearly so, narrow, crowded, somewhat linear, white, becoming spotted. Taste slightly acid. The whole plant is creamy white, becoming spotted and stained throughout with rusty-brown or foxy-red tints. The plants are usually large, long stemmed, and grow in irregular clusters on decayed tree stumps in woods. Specimens of a large size have been gathered in the fir woods near Mattapoisett, Massachusetts. Cap 3 to 5 inches broad; stem 3 to 5 inches long. The variety immaculatus differs from the typical form in not becoming spotted and in the broader gills, which are serrated.

FIGS. 7 to 9.--=Ag. (Collybia) velutipes= Curt. "Velvet-Footed Collybia."

Cap fleshy, thin, at first convex, then plane, obtuse, smooth, viscid, tawny or brownish yellow, turning dark; flesh yellowish and soft; gills slightly adnexed, pale yellow; stem tough, stuffed, externally cartilaginous, sometimes slender, but usually thick, covered with a brown velvety down, dark bay color. This is a very common species in some localities. It is densely caespitose, growing in heavy clusters on old logs and tree trunks in parks, woods, and gardens. The plants are quite gelatinous when cooked. Group figured from illustration by M. C. Cooke.

Collybia radicata Rehl. is recorded as an edible species. The plants have a thin, slightly fleshy cap, slightly umbonate, wrinkled, and glutinous at maturity; distant, white, adnexed gills, and tall, slender, rigid stem. The latter is often twisted and usually attenuated upwards, color pale brown. It has a long tapering root entering deeply into the soil. This species is solitary in habit, and is commonly found in grass, or near decayed stumps. Cap from 2 to 3 inches in diameter, stem 6 inches to 10 inches in length.

Collybia esculenta Jacq., a small species found in pine woods as well as in pastures in the spring, is recorded as edible by a number of authors. In this species the cap is nearly plane, obtuse, and smooth, brownish; gills adnate, whitish; stem very slender, fistulose, equal, tough, smooth, reddish clay color, deeply rooting.
