In woods. Pileus ^-1 in, broad, stipe l-\\ in. high. A beautiful 

 little Omphalia, growing on leaves, I have here referred to this species. 

 Some of my specimens are a little brownish on the pileus, with the 

 lamellae rather pale. It may prove to be something different. 



61. A. EPiCHYSiuM, Pers, Pileus membranaceous, rather plane, 

 umbilicate; when wet, striate, cinereous-fuliginous; when dry, pallid, 

 silk}^ or flocculose-scaly. Stipe disposed to be hollow, glabrous,

Growing on mouldy wood. Tender, soft, watery. Pileus ^-^ in. in

 Stipe somewhat stuffed, slender, glabrous, graj'-brown. Lamellse de- 

 current, thick, rather distant, gray; the edge arcuate. Spores some- 

 what elliptic, .008X-005 mm. 



In moist places in woods. Pileus ^-1^ in. broad, at first gray, then 

 becoming whitish or brownish. The specimens agree well with Fries' 

 species, except in some cases the}' are much larger. 



h. Lamellon broad, distant. 



63. A. MURALis, Sow. — Pileus somewhat membranaceous, tough,

 concolorous. Lamellae decurrent, distant, pallid.

04. A. UMiJELLiFERUs, Liuu. — Pilcus a little fleshy, convexo-plane; 

 when wet, radiate-striate; when dry, even, somewhat silky. The

 pubescent at the base. Lamellre decurrent, very distant, broadest 

 behind. Spores .0030X-0025 mm. 



Upon turf or sod in swamps and pastures, also on rotten wood; 

 somewhat gregarious. Pileus |-1 in. broad, stipe 4-1 in. high. Pileus 

 depressed in the center, the margin deflexed and sometimes waved, 

 whitish, whitish-brown or yellow, darker when wet; the stipe whitish 

 or yellowish. 



65. A. ALBOFLAVDS, u. sp. — Pilcus nosliy-membranaceous, some-
