Pileus fleshy, convex to plane, upturned at the margin in dried 

 specimens, solitary, 5-10 cm. broad; surface dry or slightly moist, 

 nearly smooth, glabrous, subshining, umbrinous, tinged with light- 

 brown in younger stages, becoming isabelline-ochraceous-melleous 

 at maturity ; context white, very thin, except at the center, without 

 characteristic odor, taste mild and peculiar, like some bulbs ; lamel- 

 lae adnexed, arcuate, crowded, rather narrow, entire and con- 

 colorous on the edges, dark-smoky to dark-violet, at length pur- 

 plish-fuliginous ; spores ovoid, smooth, umbrinous under the micro- 

 scope, about 10-12 x 7-8 fi; stipe slender, tapering decidedly up- 

 ward from a bulbous base, glabrous, solid, white, smooth, and 

 shining above the annulus, cream-colored below and longitudinally 

 striate just below and near the annulus, 10-12 cm. long, 2-3 cm. 

 thick at the base, 5-10 mm. thick at the apex ; annulus large, mem-

Type locality : New York Botanical Garden, New York City. 



Habitat : In rich, low, partly shaded soil.

 ish-umber cap, dark-violet gills, and a yellow stipe which tapers 

 upward decidedly from a bulbous base. 



Doubtful and Excluded Species 



Stropharia albocyanea (Desmaz.) Quel. Champ. Jura Vosg. 

 236. 1872. According to Harper, this species occurs with us, 

 being smaller than S. aeruginosa and having a white, dry stipe. 

 Morgan referred to it as pseudocyanea (Letell.). Peck's speci- 

 mens so named, from North River, New York, and those collected 

 by Simon Davis at North Bethlehem, New Hampshire, differ from 

 each other and from Bresadola's specimens.
