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 ; lamelle adnate or subdecurrent, 
moderately close, some of them forked near the stem, white, the 
interspaces venose ; stem nearly equal, glabrous, stuffed or hollow, 
white; spores white, minutely rough, subglobose or broadly ellipti- 
eal, .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. r 
Woods. Sandlake. July and August. 
This Russula belongs to the section Fraciies. It may be distin- 
guished from white forms of /tussula emetica by its adnate or slightly 
decurrent lamelle and by its milder taste. 
Russula uncialis. 
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 ; 
lamellee 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. 
Hydnum albidum. 
Pileus fleshy, thin, convex or nearly plane, subpruinose, white,
