white; broadly elliiDtical or subglobose, .00016 to .0002 in. long, .00012 



to .00016 broad. 



Pileus 3 to 5 lines broad, stem about 1 in. long, .5 to 1 Hue thick. 



Mossy decayed wood and stumps. Gansevoort. July. 



A small white species related to G. 3fichehana, G. muscigena and 



G. India, but differing from these by its broad ventricose lamellie. 



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 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 Mijcena vulgaris, or grayish forms of 

 M. clavicularis; in size, M. corticola. When very young the stem is 

 conical and the j)ileus is more narrow than its base. 



Mycena capillaripes, n. sp. 



Pileus membranous, campanulate, glabrous, hygrophauous, livid 

 gray or brownish and striate when moist, paler when dry, odor weak, 

 alkaline; lamellae ascending, subdistant, adnate, whitish or livid- 

 white, the edge obscurely brownish-purj)le; 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 llycena rubromarginata from which I have 

 sepai-ated it because of its smaller size, slender stem, paler coloi', 

 smaller spores and alkaline odor. It is also much smaller and paler 

 than 31. 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; lamellae 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.
