A rare but beautiful species. It is often cespitose. It departs from the character of the genus in growing on decaying wood. _Peck_, 44th Rep. N.Y. State Bot. Tricholoma decorosum is not rare in Pennsylvania. I have found it at Angora, Philadelphia and in Chester county, Pa., growing in clusters and singly. At first sight one might take it for one of the many forms of Armillaria, but even cursory examination shows the difference. It is of good consistency and flavor, having a decided mushroom taste. =T. flaves´cens= Pk.—pale yellow. =Pileus= convex, firm, often irregular, dry, _slightly silky becoming bare_, sometimes cracking into minute scales on the disk, _whitish or pale yellow_. =Flesh= whitish or yellowish. =Gills= close, white or pale-yellow, emarginate, floccose on the edge. =Stems= firm, solid, often unequal, central or sometimes eccentric, single or cespitose, colored like the pileus. =Spores= subglobose, 5µ in diameter. =Pileus= 2–3 in. broad. =Stem= 1–2.5 in. long, 4–6 lines thick. Pine stumps. Albany and Rensselaer counties. October. The species seems to be related to T. rutilans but has not the red or purplish tomentum of that fungus. It, like T. decorosum, is always lignicolous. T. rutilans is sometimes so. _Peck_, 44th Rep. N.Y. State Bot. Frequently found in New Jersey, Pennsylvania and West Virginia. Pine stumps. September to frost. _McIlvaine._ The flesh compares with that of T. rutilans, and makes an equally good dish. =T. gran´de= Pk. =Pileus= thick, firm, hemispherical, becoming convex, often irregular, dry, _scaly_, somewhat silky-fibrillose toward the margin, _white_, the margin at first involute. =Flesh= grayish-white, taste _farinaceous_. =Gills= close, rounded behind, adnexed, white. =Stem= stout, solid, fibrillose, at first tapering upward, then equal or but slightly thickened at the base, pure white. =Spores= elliptical, 9–11×6µ. =Pileus= 4–5 in. broad. =Stem= 2–4 in. long, 1–1.5 in. thick. Among fallen leaves in woods. Cattaraugus county. September. The plants are often cespitose, and then the pileus is more or less irregular and the gills somewhat lacerated. 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. _Peck_, 44th Rep. N.Y. State Bot. Mt. Gretna, Pa. Mixed woods. August to frost. _McIlvaine._ Gross when old. Young specimens of medium quality and flavor.
