Agaricaceee 



cutocybe. XXIV, fig. 8, p. 82.) Pileus 12% in. across, dark-purple, umbili- 

 cate, smooth, minutely tomentose, involute. Gills dark-purple, decur- 

 rent, 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, Mcllvaine. 



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 striae. Stem 

 hollow, twisted, fragile. Gills adnate, thick, distant, fleshy-rose, ces- 

 pitose, 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, 4ist 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. ocliropurpu'rea Berk. ochra, ocher; purpureus, purple. (Plate 

 XXIV, figs, i, 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, de- 

 current. Spores white or pale yellow. 



Pileus 2 in. broad. Stem 2. X 2 in. high, % in. thick in the center. 



August. On clayey soil in woodlands.
