This group corresponds to the tribe Dapetes of Fries. In Europe 

 there are but two species belonging to it ; in our State there are four, 

 one of which, L. deliciosus, is common to this country and Europe. 

 There is much similarity in our species, their most obvious differences 

 being in color. The pileus in all is glabrous, slightly viscid when moist, 

 more. or less zonate when young and moist, bat becoming paler and less 

 clearly zonate with age. The stem is hollow, at least when old, and 

 often adorned with spots of the same color as the milk. The color of 

 the milk pervades the whole plant, but it is less bright and clear except 

 in the spots and the young lamellae. Bruises or wounds of the lamellae 

 are apt to become greenish, and old plants are often stained with this 

 hue. The spores in all are yellowish, and the taste is mild or slowly 

 and moderately acrid. Probably all are edible, but only L. deliciosus 

 has been tested. 



Lactarius Indigo, Schw. 



Blue Lactarius. 



Pileus at first umbilicate with the margin involute, then depressed or 

 infundibuliform, indigo-blue with a silvery-gray lustre, zonate, espec- 

 ially on the margin, sometimes spotted, becoming paler and less distinctly 

 zonate with age or in drying ; lamellae close, indigo-blue, becoming 

 yellowish and sometimes greenish with age ; stem short, nearly equal, 

 hollow, often spotted with blue, colored like the pileus ; spores subglo- 

 bose, .0003 to .00035 in. long ; milk dark blue. 



Pileus 2 to 5 inches broad, stem 1 to 2 inches long, 6 to 10 lines thick. 



Dry places, especially under or near pine trees. Not rare but seldom 

 abundant. July to September. 



Lactarius subpurpureus, Peck. 

 Purplish Lactarius. 



Pileus at first convex, then nearly plane or subinfundibuliform, more 

 or less spotted and zonate when young and moist, dark-red with a 

 grayish lustre ; lamellae close, dark-red, becoming less clear and some- 

 times greenish-stained with age ; stem equal or slightly tapering upward, 

 soon hollow, often spotted with red, colored like the pileus, sometimes 

 hairy at the base; spores subglobose, .00035 to -0004 in., milk dark-red. 



Pileus 2 to 3 in. broad, stem 1.5 to 3 in. long, 3 to 5 lines thick. 



Damp or mossy ground in woods and swamps. July and August. 



At once known by the peculiar dark-red or purplish hue of the milk, 

 which color also appears in the spots of the stem and in a more subdued 

 tone in the whole plant. The color of the pileus lamellae and stem is 



* Badham says that the milk of L. deliciosus changes to a green color, but I have not 

 observed such a change.
