white } spores white, nearly smooth, .o0025 to .o003 in.; milk white, 
abundant, taste very acrid. 
Pileus 1.5 to 4 in. broad, stem .5 to 2 in. leng,5 to ro lines thick. 
Thin woods, pastures and grassy places. Common. July to Sep- 
cember. 
The glabrous or sometimes merely pruinose pileus, the crowded and 
frequently forked narrow lamelle separate this species from the other 
white ones. The lamellz are one to two lines broad, their width being 
less than the thickness of the flesh of the pileus. The stem is either 
very short or quite long, according to the place of growth, it being 
longer when growing in woods among fallen leaves than when growing in 
open grassy places. In the summer of 1883 this and the two preced- 
ing species were abundant in the town of Sandlake, and all grew in the 
same locality. By a little practice they were readily distinguishable, 
even without a close inspection. 
Most authors agree in attributing edible qualities to this species, not- 
withstanding ‘its intense acridity. Badham says that he has frequently 
eaten it, and that according to Berkeley it is preserved for winter use by 
pickling in salt and vinegar. Cordier says that it is an agreeable ali- 
ment and is eaten in many countries, and that cows eat it with avidity, 
but that it renders their milk and butter nauseous. Fries says it is edi- 
ble, and it is so classed in Curtis’ Catalogue. Gillet states that although 
it does not constitute an agreeable article of food, it is eaten in some 
parts of France, and that the Russians make frequent use of it. ‘a 
Lactarius albidus, Peck. 
White Lactarius. 
Pileus thin, plane or slightly depressed, glabrous, dry, white ; lamellz 
subdistant, adnate or slightly decurrent, white, the iterspaces venose ; 
stem equal, solid, glabrous, white ; spores white, .c003 to .00035 in.; 
milk white, taste acrid. ? 
Pileus 1.5 to 3 in. broad, stem 1 to 2 in. long, 3 to 5 lines thick. 
Thin woods. Karner. September. Very rare. 
This Lactarius has been observed but once, and then but few speci- 
mens were seen, yet it appears to be distinct from all our other white 
species in its thin pileus, subdistant lamellz, venose interspaces and 
rather slender stem. Except in color, it has some similarity to the 
next species. ; 
Lactarius varius, 2. sp. 
Variable Lactarius. 
Pileus thin, convex or nearly plane, umbilicate or centrally depressed, 
sometimes with a minute umbo or papilla, glabrous, even or obscurely 
roughened, submoist, zoneless or rarely narrowly zonate on the margin, 
gray or brown, often tinged with lilac, lamelle close, adnate or subde- 
current, whitish or cream colored, becoming dingy-greenish where 
wounded ; stem equal, elastic, glabrous, solid or spongy within, paler 
than or colored like the pileus ; spores white, .0003 to .00035 in.; milk 
white, taste tardily acrid, odor none, flesh white. 
Pileus 1 to 2.5 in. broad, stem 1 to 2.5 in. long, 2 to 4 lines thick.
