50 LACTARIAE ОҒ THE UNITED STATES 
“ Lac raro album persistit.” It was evidently on the strength of | 
the unchangeable milk that Passerini described his specimens as 
a distinct species, Г. Z/vescess. In the Vermont specimens I 
repeatedly watched the latex for fifteen minutes or even longer, 
and I could never detect any change except where the drop was 
in contact with the broken flesh. 
Krombholz’ description, accompanying his al, 57. f. 7—9,accords 
with the characters of Lactaria lividorubescens but the plate does 
not represent this species, nor does it agree with his description. 
And ai 57. f. 14, 16 can scarcely be positively referred to Lac- 
taria lividorubescens, hence I have omitted both of these in the 
plates cited. 
23. Lacraria MACULATA Peck, Ann. Вер. М. Y. St. 
Mus. 41: 74. 1888. [As Lactarius] 
Pileus fleshy, compact, convex-umbilicate, then depressed in the 
center or at length infundibuliform, gray to lilac-gray, distinctly 
zoned with concentrically arranged darker spots, viscid, glabrous, 
7-5-12.5 cm. broad, margin involute, naked, then spreading ; gills 
whitish or cream-colored, sometimes forking, close, adnate 10 
decurrent ; stem of the same color as the pileus or paler, spotted, 
equal or tapering downwards, glabrous, hollow, 2.5-5 cm. long, 
10-16 mm. thick; flesh grayish becoming lilac where wounded ; 
spores subglobose, echinulate, 10—12.5 и т diam. ; latex creamy- 
white, becoming lilac, acrid and unpleasant. 
Нав. : “Іп thin woods, and pastures " (Peck). 
Distris.: New York, Peck ; Vermont, Morgan. 
DISTINGUISHING FIELD-MARKS: This species is to be distin- 
guished from Lactaria lividorubescens Batsch by its larger size, the 
firmer flesh, and the conspicuously spotted-zoned pileus and the 
absence of an umbo. The stem is also more spotted. 5 
Lactaria maculata was first described as a variety of Lactari@ 
uvida Fr., under the name magnus, but after further field-work, 3 
was separated as a distinct species. I have not found this species, 
but from an examination of the type specimens at Albany, I con- 
sider it to be distinct from L. /ividorubescens. 
VII. ĪNSULSAE 
Pileus very viscid, entirely glabrous, some shade of yellow, | 
flesh firm, plants rather large ; gills becoming neither perceptibly 
darker with age, nor pruinose ; latex very acrid, white, unchanging
