Spores brownish-purple, 10 x 5 to (i /x. Pileus 5 to 7.5 cm. 

 broad; stem 5 cm. long, 6 to 8 mm. thick. 



On the ground in woods. Glencoe, Warrenville, Bartlett. 

 September and October. Lamellae adnate, sinuate, easily 

 separating from the stem, light-yellow in the young plant; flesh 

 of pileus and stem yellowish slowly turning to brownish when cut. 

 Stem clothed like the pileus up to the obsolete ring, white-pruinose 

 above it. 



Hypholoma Candolleanum Fr. 



Pileus date-brown becoming white, vertex somewhat ochra- 

 ceous, somewhat fleshy, acorn-shaped then campanulate, soon 

 convex and at length flattened, obtuse and unequal, smooth, 

 even. Wil appendiculate, white, at length becoming fuscous. 



Lamellae rounded-adnexed, then separating, crowded, viola- 

 ceous, then fuscous-cinnamon, the edge at first whitish. 



Stem fistulose at the apex, solid at the base, somewhat thick- 

 ened, fibrillose, white, striate at the apex. 



Pileus 5 to 10 cm. broad; stem 7.~) cm. long, 1 to 8 mm. thick. 

 Densely cespitose, fragile, very hygrophanous. 



Gregarious in short grass in lawns under trees, after rain-. 

 Spring to autumn. Mcllvane notes that "the gills are cream- 

 colored at first, then purplish, then very dark." //. incertum Peck, 

 seems to be very near this. 



Hypholoma appendiculatum Bull. 



Pileus date-brown then tawny, becoming ochrey-pale when 

 dry, fleshy-membranaceous, thin, ovate then expanded, a1 length 

 flattened, obtuse, smooth, when dry slightly wrinkled, somewhal 



sprinkled with atoms; veil fringing the margin of the pileus, 

 fugacious, white. 



Lamellae somewhat adnate, crowded, arid, white then flesh- 

 colored, at length fuscous. 



Stem fistulose, equal, smooth, white, pruinate at the apex. 



Pileus 5 to 10 cm. broad; stem 7.5 cm. long. 1 to 6 mm. thick. 



Densely cespitose, very fragile and hygrophanous, much 

 thinner and more fragile than //. ( 'andolleanum. (Stevenson. I 



About old stumps in woods. 

 Hypholoma subaquilum Banning. 



Pileus brown, convex, smooth, hygrophanous, often shaded 

 into ochre at the margin, veil delicate, silk-like, encircling and 

 covering the marginal extremities of the lamellae but forming no 

 ring on the stem; flesh white, turning umber when cut. 



Lamellae adnexed or nearly free, close, forked, umber. 



Stem cespitose, regular, hollow, silk)-, white. 



In dense cespitose clusters in a woodland pasture. War- 

 renville. September and October. Lamellae watery-cinnamon, 

 becoming umber; veil woven, concealing the lamellae in the young 

 plant, soon disappearing: stem pruinate at the apex. Pileus
