Grassy places. Menands. Albany county. September. Edible. Resembling Armillaria mellea, but distinguished from it by the absence of a collar from the stem, by the more decidedly decurrent lamellæ and by the solid stem. It is also more agreeable in flavor. It is related to C. illudens in habit and manner of growth. _Peck_, 51st Rep. N.Y. State Bot. =Spores= 8×5µ _Peck_. October 15, 1898. Identified by Professor Peck. September until frost. Grows in great clusters about roots, etc., at Mt. Gretna. Frequently much water-soaked and uninviting. Taste variable, sometimes strong, woody. It is edible, but care should be exercised in collecting to get young, fresh groups. =C. socia´lis= Fr.—_socius_, a companion. =Pileus= about 1 in. broad, pale-yellowish with a reddish tinge, fleshy, convex then expanded, acutely umbonate especially when young, even, smooth, dry. =Flesh= moderately thin, white. =Stem= 1 in. long, 2 lines or a little more thick, solid, fibrous, commonly ascending, smooth, reddish, the rooting base hairy. =Gills= plano-decurrent, scarcely crowded, becoming yellow. _Fries._ A very pretty species, densely gregarious, inodorous. The stem is sheathed-hairy at the base like Marasmius peronatus. Its greatest affinity is with A. vernicosus, of which it is perhaps a variety. _Stevenson._ Quite common in pine woods of New Jersey. Though small, goodly messes of it may be gathered from its patches. The caps make a pleasing dish. *** _Pileus becoming yellow._ None reported as tested for edibility. **** _Pileus greenish or becoming pallid._ =C. odo´ra= Bull.—_odorus_, fragrant. (Plate XXIV, fig. 9, p. 82.) Fragrant. =Pileus= about 2 in. across, flesh rather thick, tough; soon plane and wavy, even, smooth, pale dingy green, silky when dry. =Gills= adnate, rather close, broad, greenish or pallid. =Stem= about 1–1½ in. long, 2 lines thick, base incrassated, elastic, stuffed. =Spores= elliptical, 6–8×4–5µ. In woods. _Massee._ Readily distinguished by the strong, aniseed smell, dingy bluish-green pileus, and the pallid or greenish gills. Sometimes somewhat cespitose. Tough; size variable, color varies between pale green and greenish-gray, usually all colored alike, but the gills are sometimes white; smell pleasant, spicy, especially when dry. _Fries._ =Spores= 6×5µ _K._; 8×4µ _B._ A rather delicate, even exquisite dish. _Cooke._ Edible. Exceedingly spicy. The flavor is pleasant, but rather strong. A few specimens mixed with others of like texture but less flavor make a tasty dish.
