OMPHALIA. 387 



form of 0. pyxldata ; it differs in many particulars from the 

 description and figure of Fries, especially in the very 

 flexuous stem, thickened upwards, whereas Fries says the 

 stem is remarkably equal and straight. The pileus is also 

 much lobed in Cooke's figure, and the specimens were found 

 on charcoal beds. 



A very elegant species, growing in swamps. The bright 

 orange colour of the glabrous pileus distinguish this from 

 every other species. Stem hollow, 2-3 in. long, 1 line and 

 more thick, remarkably equal, straight, even, glabrous, 

 yellowish. Pileus membranaceous, umbilicate at first then 

 depressed, 1-2 in. and more broad, even, glabrous, convex 

 and striate at the margin. Gills very deeply and truly 

 decurrent, 1 line broad, arcuate, white. (Fries.) 



Tar. aurea. Mass. 



Pileus 1-2 in. across, flesh thin ; very regular, infundibu- 

 liform, smooth, even, margin drooping, bright golden-yellow ; 

 gills slightly decurrent, crowded, 1 J line broad, thin, white ; 

 stem about 2 in. long, li-2 lines thick, equal smooth and 

 polished, coloured like the pileus, hollow, white and tapering 

 at the base ; spores elliptical, 7 X 3'5 /a. 



On Sphagmim in swamps. 



Figured by Cke., Illustr., pi. 1152b, as a form of 0. Posiii, 

 but probably a distinct species. 



Omphalia pyxidata. Bull. 



Pileus ?r-l in. across, membranaceous, umbilicate then 

 infundibuliform, almost glabrous, radiately striate, brick- 

 led or^with a rufescent tinge when wet, hygrophanous, 

 whitish and minutely silky under a lens when dry ; gills 

 decurrent, rather distant, narrow, flesh-colour then yellowish ;

Am.ong short grass, &c. 



Stem stuffed then hollow, tough, 1 in. long, about 1 line 

 thick, equal, round, glabrous or pruinose, pallid then reddish. 

 Pileus membranaceous, pellucid, umbilicate then infundi- 

 buliform, about 1 in. broad, very hygrophanous, glabrous
