96 Forty- fifth Report on the State Museum. 



Yar. chrysea. (Agaricus chryseus, Rep. 23, p. 85.) 



Whole plant yellow, lamellae rather narrow. 



This differs from the true 0. chrysophylla so slightly that it 

 seems best to regard it as a mere variety of that species. The 

 pileus varies in depth of coloring and the spores in the American 

 plant, from which the dimensions here given were taken, are 

 somewhat longer than the dimensions ascribed to those of the 

 European plant. This fungus is not common. 



Omphalia pyxidata Bull. 

 Cup-shaped Omphalia. 



(Hym. Europ. p. 157. Syl. Fung. Vol. V, p. 313.) 



Pileus at first convex or nearly plane and umbilicate, then 

 funnel-form, glabrous, hygrophanous, brick-red or reddish-brown 

 when moist and wholly radiate-striate, or on the margin only, 

 pale when dry and flocculose or slightly silky ; lamellae narrow, 

 subdistant, decurrent, tinged with flesh-color, then yellowish; 

 stem equal, tough, glabrous, stuffed or hollow, pallid or reddish; 

 spores subelliptical, .00025 to 000 \ in. long, .0001'. to 0002 broad. 



Pileus 6 to 12 lines broad; stem about 1 in. long. 1 line thick. 



Grassy or mossy ground in pastures. Lewis county. September. 



This is evidently a rare species with us, as it has not been 

 observed since its discovery here in 1870. 



Omphalia striipilea Fr. 



Striate-capped Omphalia. 



(Hym. Europ. p. 157. Syl. Fung, vol. V, p. 314) 



Pileus membranous, convex or plane, umbilicate, never funnel- 

 form, glabrous, hygrophanous, livid brown and beautifully striate 

 when moist, even and paler when dry ; lamellae not crowded, 

 slightly decurrent, whitish ; stem equal, rather firm and tough, 

 glabrous, hollow, often flexuous, brownish; spores nearly or 

 quite globose, .00025 to .0002a in. broad. 



Pileus 6 to 12 lines broad ; stem 1 to 1.5 in. long, about 

 1 line broad. 



in groves of spruce and balsam fir. Essex county. September.
