Clitocybe laccata is made the type of a new genus by Berkeley and Broome. Massee accepts the genus but it is not generally accepted by the standard authors. It is a well defined genus, and a fitting place for C. laccata, C. amethystina, C. ochropurpurea, C. tortilis, which it puzzles anyone to identify as Clitocybe. =C. amethys´tina= Bolt.—_amethystinus_, color of an amethyst. (Plate XXIV, fig. 8, p. 82.) =Pileus= 1–2½ in. across, dark-purple, umbilicate, smooth, minutely tomentose, involute. =Gills= dark-purple, decurrent, broad. =Stem= 2–3 in. high, fibrillose, purple, streaked with white fibrils, equal, densely covered with white tomentum at base. Also written _Clitocybe laccata amethystina_ Sacc. “In my opinion it is a good species and should be kept distinct as Bolton gave it, and not be tacked on to C. laccata as a variety. I should write it Clitocybe amethystina Bolt.” _Peck_, letter September 17, 1897. New York, _Peck_, Rep. 41; New Jersey, _Sterling_; Mt. Gretna, Pa., on wood soil, June to frost, 1897–1898, _McIlvaine_. Generally included in C. laccata as a variety, and has therefore been reported under that name. Great quantities of C. amethystina grew in troops on beds made up of wood earth about the cottages at Mt. Gretna, Pa. The woods over them is dense. The caps are tough, but they cook readily and make a pleasing dish. =C. tor´tilis= Bolt.—_tortilis_, twisted. =Pileus= membranaceous, convexo-plane then depressed, obscurely marked with radiating striæ. =Stem= hollow, twisted, fragile. =Gills= adnate, thick, distant, fleshy-rose, cespitose, small, irregular, pileus and stem rusty in color. Hard ground in an old road. Sandlake. August. A species closely allied to C. laccata and appearing like an irregular dwarf form of that species. Sometimes cespitose. _Peck_, 41st Rep. N.Y. State Bot. Excepting that this fungus is frequently found with C. laccata, and might be taken for a new species if not here described, it would not be separated from C. laccata. Its edible qualities are similar. =C. ochropurpu´rea= Berk.—_ochra_, ocher; _purpureus_, purple. (Plate XXIV, figs. 1, 2, 3, 4, p. =82=.) =Pileus= subhemispherical, at length depressed, fleshy, compact, tough, pale yellow, slightly changing to purplish, cuticle easily separable; margin inflexed, at first tomentose. =Stem= paler, here and there becoming purplish, solid, swollen in the middle, occasionally equal. =Gills= thick, purple, broader behind, decurrent. =Spores= white or pale yellow. =Pileus= 2 in. broad. =Stem= 2½ in. high, ¾ in. thick in the center. August. On clayey soil in woodlands.
