modified by grayish and yellowish hues. In age and dryness the zones 

 are less clear, and dried specimens can scarcely be distinguished from 

 L. deliciosus. 



Lactarius deliciosus, Fr. 



Delicious Lactarius. 

 Agaricus deliciosus L. 



Pileus at first convex and subumbilicate, then nearly plane or subin- 

 fundibuliform, yeUotvish-orange or grayish-orange varied by brighter 

 spots and zones, fading to grayish-yellow when old or dry ; lamellae 

 close, orange-colored with paler reflections, less clear and often greenish- 

 stained with age ; stem nearly equal, stuffed or hollow, often spotted, 

 colored like the pileus, sometimes hairy at the base ; spores subglobose, 

 .0003 to .0004 in.; milk orange-colored. 



Pileus 2 to 5 in. broad, stem 2 to 4 in long, 4 to 8 lines thick. 



Woods and open places, but especially in mossy swamps. Common. 

 July to September. Edible. 



This is the most common species of its group. It grows both in wet 

 and in dry places, and in acerose, frondose or mixed woods. It has an 

 excellent reputation as an edible fungus. Badham says it is one of the 

 best of fungi and that its flesh is firm, juicy, sapid and nutritious. One 

 writer pronounces it the most delicious mushroom known. The best 

 method of cooking is said to be, to bake three-fourths of an hour in a 

 close covered dish, having seasoned it with pepper, salt and butter. 



Badham states that the milk turns green on exposure to the air. 

 Wounds of the flesh and lamellae often do, but I have not observed this 

 change in the color of the milk. 



Lactarius Chelidonium, Pech. 

 Celandine Lactarius. 



Pileus at first convex, then nearly plane and umbilicate or centrally 

 depressed, grayish-yellow or tawny, at length varied with bluish and 

 greenish stains, often with a few narrow zones on the margin , lamellae 

 narroiu, close, sometimes forked, anastomosing or wavy at the base, 

 grayish-yellow; stem short, subequal, hollow, colored like the pileus ; 

 spores globose, .0003 in.; milk sparse, saffron-yelloio; taste mild. 



Pileus 2 to 3 in. broad, stem i to 1.5 in. long, 4 to 6 lines thick. 



Sandy soil, under or near pine trees. Saratoga and Bethlehem. 



The milk of this species resembles in color the juice of celandine, 

 Chelido)iii(m majus. It is paler than that of L. deliciosus. By this 

 character and by the dull color of the pileus, the narrow lamellae, short 

 stem and its fondness for dry situations, it may be separated from the 

 other species. Wounds of the flesh are at first stained with the color of 

 the milk, then with blue, finally with green. A saffron color is some- 

 times attributed to the milk of L. deliciosus, which may indicate that 

 this species has been confused with that, or that the relationship of the 

 two plants is a closer one than we have assigned to them. 



Milh at first white, changioig color on exposure to the air. 



In this group, wounds of the lamellae and flesh generally assume the 

 changed color of the milk after a brief exposure to the air.
