Lactarius uvidus, Fr. 



Moist Lactarius. 



Pileus at first convex, then nearly plane or centrally depressed, 

 glabrotis, viscid, whitish, grayish-brown or livid-brown, generally with a 

 slight tinge of pink, sometimes obscurely zonate or marked with darker 

 spots, either with or without a small umbo; lamellae rather narrow, thin, 

 close, white or yellowish, becoming lilac where cut or bruised; stem 

 equal or slightly tapering upward, stuffed or hollow, glabrous, viscid, 

 whitish or pallid ; spores globose or broadly elliptical, yoUojvish, 00035 

 to .00045 ii^-l "^ilk white, changi7ig to lilac, taste acrid. 



Var. magnus. Plant large, pileus obscurely zonate or marked with 

 darker spots more or less concentrically arranged. 



Pileus I to 2 in. broad, stem 1.5 to 3 in. long, 3 to 6 lines thick. 



Wet mossy places in woods and swamps. Adirondack mountains and 

 Sandlake. July and August. 



This species is not very common. It is readily recognized by the 

 lilac color assumed by the milk and the wounds of the flesh and lamellae. 

 The variety occurs in Vermont where it was observed by Mr. A P. 

 Morgan. 



Lactarius chrysorheus, Fr. 



Yellow-milk Lactarius. 

 Agarictis zonarius, Bolt. 



Pileus convex, umbilicate or centrally depressed, becoming infundi- 

 buliform, glabrous, yellowish, sometimes tinged with flesh-color, adorned 

 with bright-colored zones and spots, the margin at first involute and 

 pruinose-tomentose • lamellae thin, close, adnate or decurrent, yellowish, 

 some of them forked ; stem equal, glabrous, hollow, white or colored 

 like the pileus, sometimes spotted ; spores subglobose, .0003 to .00035 

 in.; milk white, becoming yelloio, taste acrid. 



Pileus I to 3 in. broad, stem 8 to 15 lines long, 3 to 5 lines thick. 



Thin woods or open places. Bethlehem and Sandlake. July and 

 August. Not common. 



Fries describes this species as having a dry pileus, but in our speci- 

 mens it appeared to be slightly viscid when moist. The milk in the 

 European plant is said to change color quickly, in ours the change 

 takes place slowly. The spots of the pileus are usually small and nu- 

 merous and sometimes concentrically arranged. They, as well as the 

 zones, have a golden-yellow or pale-orange hue. They, together with 

 the color of the pileus, distinguish this species from the ne.\t. and the 

 change in the color of the milk separates it from L. insulsns. The plant 

 described in the Twenty-third Report under this name belongs to the 

 next species. 



Lactarius theiogalus, Fr. 



Sulphur-milk Lactarius. 



Agaricus theiogalus, Bull. 



Pileus fleshy, thin, convex, then depressed, even, glabrous, viscid, 

 tawny -reddish J lamellae adnate or decurrent, close, pallid or reddish :
