72 Journal of Mycology [Vol. 14 



Solitary or gregarious ; growing on manure in woods. Prob- 

 ably common enough, but not distinguished from semiglobatus, 

 which it closely resembles. Fries gives the color of the younger 

 pileus livid-yellow, of the adult pileus egg-yellow. Pileus 2-3 cm. 

 in diameter; the stipe 7-12 cm. long, 3-5 mm. thick. 



15. STROPHARIA SICCIPES KARSTEN, Symb. ad 

 Myc. Fenn IX, 46. 



Pileus fleshy, hemispheric, then expanded, obtuse ; the sur- 

 face smooth and glabrous, viscid, argillaceous-white, changing 

 to yellow when dry. Stipe stuflfed, becoming hollow, straight or 

 flexuous, slightly fibrillose, dry, pallescent ; the annulus incom- 

 plete, dry, distant. Lamellae broad, adnate, subdecurrent, argil- 

 laceous, then brownish-nebulous, at length brown : spores brown- 

 ish and pellucid, elliptic, 12-15x7-9 mic. 



Growing on cow manure ; New York, Feck. Pileus 2-3 cm. 

 in diameter ; stipe 4-7 cm. long, 2 mm. thick. 



h. Pileus ovoid then expanded, umbonafe. 



16. STROPHARIA SUBMERDARIA Britzelmayr, 

 Hym. Sudb. VIII. 



Pileus fleshy, ovoid, then convex and expanded, subum- 

 bonate ; the flesh thin, white ; the surface smooth and glabrous, 

 viscid, cream-color to pale ochre, becoming ochre-yellow in the 

 center; the veil white, flocculose. mostly appendiculate. Stipe 

 tapering upward from a thickened base, flexuous. with a narrow 

 tubule, white, dry, silky fibrillose ; the slight annulus near the 

 apex. Lammelae broad, close, adnate, pale ochraceous becoming 

 mottled by the spores, at length subdecurrent purple and brown; 

 spores purple-brown, elliptic-oblong, 10-12 x 7-8 mic. 



Subcaespitose ; growing on cow manure ; Preston, O. Pileus 

 3-5 cm. in diameter; stipe 3-5 cm. long. 3-5 mm. thick. This is 

 probably the much larger variety alluded to by Fries under 

 Str. merdaria. 



17. STROPHARIA UMBONASCEUS, Stropiiaria um- 

 BONESCEUs Saccardo, Sylloge V. 1887 ; A. (Stropiiaria) um- 

 bonatesceus Peck, 30 N. Y. Rep. 1877. 



Pileus at first ovoid-conic, then expanded and umbonate, 

 smooth, viscide, yellow, the umbo inclining to reddish. Stipe tall, 

 slender, hollow, generally a little paler than the pileus. Lamellae 

 broad, plane, then ventricose, blackish-brown with a slight oliva- 

 ceous tint; spores purplish-brown, almost black, 15-18 x 10 mic. 



Growing on manure in pastures; New York, Peck; Preston, 

 O. Pileus 1-2.5 cm. in diameter; stipe 7-10 cm. long. This 

 seems closely related to Str. mammillata Kalchbr.
