hollow, r.ithor equal, below the annuliis covered with reddish-brown 

 scales like those of the pileiis, above the annulus smooth and white- 

 Lamellas free, ventricose, white then reddish-brown, finally black. 

 Spores cymbiforin. .008— .009 mm. in length. (See Plate VIII.) 



Growing about old stumps and trees in woods. Cffispitose; pileus 

 about 1 in. in height, expanding to a diameter of 1^-2^ in., then split 

 and revolute; stipe 4-6 in. long, about ^th of an inch in thickness. This 

 species is readily distinguished b}' its persistent reddish-brown scales 

 upon the pileus and lower part of the stipe. 



3. C. VARiKGATUs, Peck. Pileus fleshy, thin fragile, oblong-ovate 

 then campanulate, obtuse, hygrophanous, pale watery brown when 

 moist, whitish or cream-color when dry, variegated by scales or 

 patches of a superficial ochraceous tomentum; the margin finely 

 striate. Stipe equal, brittle, hollow, white, at first peronate-annulate, 

 then floccose pruinose. LamelljB lanceolate, free, white then ros}'- 

 brown, finally black. Spores somewhat elliptic, .0083 X. 0056 mm. 



On ohl logs and on the ground in damp woods. Densel,v csespitose; 

 pileus 1-2 in. in diameter, an<l the same in height, stipe 3-5 in. long, and 

 ^4 an inch thick. When young the whole plant is coated b}' an 

 abundant superficial floccose tomentum; this soon breaks up into loose 

 scales or patches which peel off in flakes. 



b. Pileus covered with minute scales. 



4. C ATKA.MKNTARIUS, Bull. — Pilcus somcwliat fleshy, ovate ex- 

 panded, the vertex spotted with innate scales. Stipe hollow, firm, 

 zonate within; the annulus abrupt, fugacious. Lamellse free, ven- 

 tricose. :it first white, then purplish brown, at length blackish. 

 Spores elliptic .009X.005 mm. 



About old stumps .and on rich soil along country paths and roads. 

 In dense groups, cicspitosc. Pilcus 1^2^ in. in height, expanding to 

 3 in. or more; stipe 3-6 in. long, an<l nearly A an inch thick. The 

 young plant obt se, cheesy-soft, the pileus nigose-i)licate, lacunose and 

 lobed; when fully grown, the pileus even, white-cinereous, with brown 

 KcaleH. 



5. C. Kt'8CE8c;EN8, Sclirefl". — Pileus somewlint membranaceous, ovate- 

 expanded, nf>t polished; the disk a little fleshy, even or rimose, scaly. 

 Stipe hollow, equal, fragile, somewhat fibrillose, scarcely annulate. 

 Lainelhe attached. uinl)er black. Spores oliliquc. .ipiculate, .010X.006
