I^Khite; broadly elliptical or subglobose, .00016 to .0002 iu. long, .00012 

 ^K) .00016 broad. 

 p Pileus 3 to 5 lines broad, stem about 1 iu. long, ..5 to 1 line thick. 



Mossy decayed wood and stumps. Gansevoort. July. 



A small white species related to G. Michehana, C. muscirjena and 

 C. India, but differing from these by its broad ventricose lamelkt-. 



Omphalia subgrisea, n. sp. 



Pileus membranaceous, convex or nearly plane, glabrous, striatu- 

 late, grayish-brown with a paler margin; lamellae distant, arcuate- 

 decurrent, cinereous; stem slender, short, stuffed, generally curved, 

 sprinkled with minute mealy jiarticles, 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, 

 Adii'ondack mountains. July. 



In color this plant resembles Mijcena vulgaris, or grayish forms of 

 J/, clavicularis; in size, 31. 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; lamellse 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 rubromarginaia 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 ami puler 

 than 31. purjjureofusca. 



Mycena crystallina, n. sp. 



Pileus membranous, at hrst conical or convex, then nearly plauo, 

 sometimes Avith a slight umbo and reflexed margin, even or obscurely 

 striate on the margin, everywhere beset with minute shining viscid 

 glandular particles, pure white; lamelhe narrow, thin, luhiate, close, 

 white; stem short, slender, hollow, colored ami adorned like the 

 pileus, attached by white woolly hairs. 



Pileus 2 to 5 lines broad; stem 4 to 8 lines long.
