=Cap= 1½ in. across, convex, broadly umbonate, margin involute, yellowish-brown, silky, innately fibrillose, shining, when young the cap is round, margin involute. =Veil= white, fibrillose, fugacious, leaving no trace on stem. =Flesh= thick in center, solid, close-grained, white, tinged with brown. Tastes strongly as radishes. Skin partially detachable. Gills exceedingly beautiful in their deep claret-color, which is permanent, decurrent. =Stem= 3 in. long, shining, smooth, white near top, brownish below, equal, fibrous, stuffed, skin removable. On ground among pines, near station, Mt. Gretna, Pa. August to frost. Solitary, gregarious and cespitose. Taste and smell like radishes. The caps cook well and are of fair flavor. Makes good patties and croquettes. _C. cinnabarinus_, Var. 1. Mt. Gretna, Pa., August to frost. On decaying chestnut stumps. Cap 1 in. across, shining, convex, orange-brown, white on margin and under minute appressed squamules, but few on margin; apparent remnant of a veil on cap, as a viscid skin. Gills rounded behind, slightly emarginate, like Tricholoma, grayish-brown when young, becoming a brilliant scarlet, unequal. Stem 2 in. high, over ¼ in. thick, white, covered with brownish-orange appressed squamules, often with stained marking of veil or fragments of veil as ring. Cespitose, connate. Taste and smell strong like radishes. Flavor in dish is decided but pleasant. Makes good patties and croquettes. Specimens were identified by Professor Peck as C. cinnabarinus, as were those of the preceding. The variations are so great that I give this place as a variety. =C. sanguin´eus= Fr.—_sanguis_, blood. =Pileus= 1–1½ in. broad, _blood-color_, becoming slightly pale when dry, fleshy, thin, convex then plane, obtuse, occasionally depressed, silky or squamulose. =Flesh= reddish, paler. =Stem= 2–3 in. long, 2–3 lines thick, stuffed then hollow, equal (rather attenuated than thickened at the base), here and there flexuous, with fibrils of the same color, almost darker than the pileus. Cortina arachnoid, fugacious, red blood-color. =Gills= adnate, crowded, 2–3 lines broad, quite entire, dark blood-color. Wholly _dark blood-color_, the stem when compressed pouring forth bloody juice. Odor of radish. Thinner than species nearest to it. The spores are ochraceous on a white ground, somewhat ferruginous on a black ground. _Fries._ =Spores= 6×4µ _W.G.S._ North Carolina, _Curtis_; Massachusetts, _Sprague_, _Farlow_, _Frost_; Connecticut, _Wright_; New York, _Peck_, 23d Rep.
