white; broadly elliptical or subglobose, .00016 to .0002 in. long, Oe 
to .00016 broad. 
Pileus 3 to 5 lines broad, stem about 1 in. long, .5 to 1 line thick. 
Mossy decayed wood and stumps. Gansevoort. July. 
A small white species related to C. Micheliana, C. muscigena: and 
C. ludia, but differing from these by its broad ventricose lamellx. 
Omphalia subgrisea, 7. sp. 
Pileus membranaceous, convex or nearly plane, glabrous, striatu- 
late, grayish-brown with a paler margin; lamelle distant, arcuate- 
decurrent, cinereous; stem slender, short, stuffed, generally curved, 
sprinkled with minute mealy particles, colored like the pileus. 
Pileus 2 to 3 lines broad; stem 6 to 10 lines long. 
Decayed wood of birch, Betula lutea. Blue Mountain lake, 
Adirondack mountains. July. 
In color this plant resembles Mycena vulgaris, or grayish forms of 
M. clavicularis; in size, M. corticola. When very young the stem is 
conical and the pileus is more narrow than its base. 
Mycena capillaripes,, n. sp. 
Pileus membranous, campanulate, glabrous, hygrophanous, livid 
gray or brownish and striate when moist, paler when dry, odor weak, 
alkaline; lamellz ascending, subdistant, adnate, whitish or livid- 
white, the edge obscurely brownish-purple; stem slender, almost 
capillary, fragile, glabrous, hollow, colored like the pileus; spores 
narrowly elliptical, .0003 in. long, .00016 broad. 
Pileus 3 to 5 lines broad; stem 1.5 to 2.5 in. long, scarcely .5 line 
thick. 
Under pine trees. Karner. August. 
This species is related to Mycena r ubromarginata from which I have 
separated it because of its smaller size, slender stem, paler color, 
smaller spores and alkaline odor. It is also much smaller and paler 
than JL. purpureofusca. 
Mycena crystallina, n. sp. 
Pileus membranous, at first conical or convex, then nearly plane, 
sometimes with a slight umbo and reflexed margin, even or obscurely 
striate on the margin, everywhere beset with minute shining viscid 
glandular particles, pure white; lamelle narrow, thin, adnate, close, 
white; stem short, slender, hollow, colored and adorned like the 
pileus, attached by white woolly hairs. 
Pileus 2 to 5 lines broad; stem 4 to 8 lines long.
