Collybia cremoracea, 



Pileus thin, submembranous, convex or campauulate, obtuse, dry, 

 slightly silky, dingy cream-colored, the margin sometimes wavy ; 

 lamellae broad, ventricose, emarginate, with a decurrent tooth, 

 whitish ; stem slender, equal, slightly silky, stuffed or hollow, pallid 

 or colored like the pileus ; spores subglobose or broadly elliptical, 

 about .00025 in. long, .0002 in. broad. 



Plant 1.5 to 2 in. high, pileus 6 to 12 lines broad, stem 1 to 2 lines 

 thick. 



Thin woods. Gansevoort. August. 



The species belongs to the section L^evipedes. 



Collybia liygrophoroicles, 



Plate 2. Fig-s. 23-26. 



Pileus subcorneal, then convex or expanded, smooth, hygrophanous, 

 reddish or yellowish-red when moist, paler when dry; lamellae broad, 

 subdistant, rounded behind or deeply emarginate, eroded on the 

 edge, whitish ; stem subequal, striate, stuffed or hollow, whitish ; 

 spores subelliptical, .0002 to .00025 in. long, .00016 in. broad. 



Plant subcaespitose, 2 to 3 inches high, pileus 1 to 1.5 inches broad, 

 stem 2 to 3 lines thick. 



Decaying half-buried wood. Knowersville. May. 



The young pileus resembles that of Hygrophorus corucus, both in 

 shape and in color. When dry it becomes pallid or subochraceous.

Mycena luteopalleus. 



Pileus submembranous, convex, glabrous, striatulate on the margin 

 when moist, bright-yellow, paler when dry ; lamellae subdistant, 

 slightly arcuate, yellow ; stem equal or slightly tapering upward, 

 smooth, hollow, yellow, furnished at the base with yellow hairs and 

 fibrils. 



Plant scattered or caespitose, about 2 in. high, pileus 3 to 6 lines 

 broad, stem about 1 line thick. 



Among fallen leaves in woods. Adirondack mountains. August. 



It resembles Hygrophorus parvulus in color, but it is readily dis- 

 tinguished from that species by its subcaespitose mode of growth, its 

 proportionately longer and more slender stem and the yellow hairs at 

 its base.
