Inocybe asterospora Quel. 



Pileus bistre, stuffed with brown striae, convex, umbonate, 

 cracked. 



Lamellae emarginate, ventricose, whitish-bistre then cinnamon. 



Stem stuffed, firm, bulbous, furnished with a separable cuticle, 

 reddish, pubescent, with brown striae. 



Spores subglobose, warted, 10 to 11 /a. 



Under trees in open woods. Winfield. September. Pileus 

 1.5 to 2.5 cm. broad; stem 2.5 to 5 cm. long. The bulb is small 

 and submarginate. Bears a superficial resemblance to /. rimosa, 

 but the spores of the latter species are even. 



Inocybe geophylla Sow. 



Pileus normally white, somewhat fleshy, conical thenexpanded, 

 umbonate. dry, becoming silky-even, then covered with long 

 longitudinal fibrils from the cuticle gaping open; flesh white. 



Lamellae rather broad, crowded, ventricose, almost free, 

 whitish then clay-fuscous, at length earth-colored.

 smooth, white or tinged with the color of the pileus and white- 

 mealy at the apex; cortina fibrillose. 



The pileus varies in color, violaceous-lilac, fuscous, brick-red 

 or yellowish. 



Pileus 1 to 2 cm. high and broad; stem 5 to 7.5 cm. long, 

 2 to 4 mm. thick. 



Woods, Winfield, Glen Ellyn and Glencoe. June and July. 

 Pileus in our plants often nearly white, varying isabelline. 



Inocybe lanuginosa Bull. 



Pileus umber, becoming yellow, slightly fleshy; campanulate 

 becoming expanded, somewhat umbonate, fioccose-scaly ; flesh of 

 pileus and stem whitish. 



Lamellae separating free, broad, ventricose, crowded, pallid 

 clay-color. 



an solid, tough, equal, whitish-fuscous, squamulose-fibril- 

 lose with fuscous down at the base, wliite-pulvenilent at the apex. 



Pileus 2.5 cm. broad; stem :; to ."> cm. long, 2 to 4 mm. thick. 



On the ground in woods, Glencoe. According to .Massee, 

 Agaricus sabuletorum B. and ('.. Grev. L9: 103, is a synonym. 



Inocybe rigidipes Pk. 



Pileus thin, convex or subcampanulate becoming expanded, 

 umbonate, squamulose, striate on the margin when dry, tawny- 

 gray. 



Lamellae broad, subdistant, narrowed behind, slightly ad- 

 nexed, tawny-ochraceous, commonly whitish on the edge. 



Stem rather slender, flexuous, rigid, firm, solid, slightly 

 pruinose, colored like the pileus. 



Spon- globose, echinate, 12.5 /*. Pileus 12 to 24 mm. broad; 

 stem 4 to 6 cm. long, 2 mm. thick.
