resume the bright-red hue of the fresh plant. Often several basidia 

 grow from the same filament. 



Russula albida. 



Pileus thin, broadly convex, then expanded or depressed, gla- 

 brous, viscid when moist, white, sometimes slightly tinged with yel- 

 low, the spreading or erect margin at length slightly and narrowly 

 tuberculose-striate, flesh white ; lamellae adnate or subdecurrent, 

 moderately close, some of them forked near the stem, Avhite, the 

 interspaces venose ; stem nearly equal, glabrous, stuffed or hollow, 

 white : spores white, minutely rough, subglobose or broadly ellipti- 

 cal. .00035 in. long, .0003 in. broad ; taste mild or bitterish. 



Plant 1 to 3 in. high, pileus 1 to 2.5 in. broad, stem 3 to 6 lines 

 thick. 



Woods. Sandlake. July and August. 



This Russula belojigs to the section Fragiles. It may be distin- 

 guished from white forms of Bussula emetica by its adnate or slightly 

 decurrent lamellae and by its milder taste. 



Russula uucialis. 



Pileus thin, convex, then expanded or centrally depressed, viscid 

 when moist, glabrous or very minutely rivulose-granulose, red or 

 pinkish-red, the margin obscurely tuberculose-striate, flesh white ; 

 lamellae moderately close, narrowed toward the stem, at which a few 

 of them are sometimes forked, adnate or slightly emarginate, white, 

 the interspaces venose ; stem equal, glabrous, stuffed or spongy 

 within, white or reddish ; spores white, globose, rough, .0003 to 

 .00035 in. in diameter ; taste mild. 



Plant 1 to 1.5 in. high, pileus 1 to 1.5 in. broad, stem 2 to 4 lines 

 thick. 



Thin woods. Sandlake. June and July. 



A small species, generally about 1 in. high, with the pileus about 

 the same in breadth. Like the preceding species, to which it is 

 closely related, it belongs to the white-spored group of the section 

 Fragiles, a group to which Europe contributes but a single mild 

 species. The color of the pileus is nearly uniform and generally a 

 pale-red or pinkish-red. The lamellae in the fresh plant are white, 

 but in the dried specimens they are pallid.
