178 MUSHROOMS, EDIBLE AND OTHERW ISE 



Lactarius scri/luus. J-'r. 



Serifluus means flowing with serum, the watery part of milk. 



The pileus is fleshy, depressed in the center, dry, smooth, not zoned, tawny- 

 brown, margin thin, incurved. 



The gills are crowded, light-brown, or yellowish, milk scanty and watery. 



The stem is solid, equal, paler than the pileus. Spores, 7-8/*. 



It differs from L. subdulcis in having a solid stem and perhaps a shade darker 

 color. Found in woods, July to November. 



Lactarius corrugis. Pk. 

 The Wrinkled Lactarius. Edible. 



Corrugis means wrinkled. 



The pileus is convex, plane, expanded, slightly depressed in the center ; 

 surface of the cap wrinkled, dry, bay-brown ; margin at first involute. 



The gills are adnexed, broad, yellowish or brownish-yellow, growing paler 

 with age. The stem is rather short, equal, solid, pruinose, of the same color as 

 the pileus. The spores are subglobose, 10-13^. 



This species looks very much like L. volemus, and its only essential difference 

 is in the wrinkled form and color of the pileus. The milk when dry is very sticky 

 and becomes rather black. It has just a touch of acridity. 



Any one determining this species will not fail to note the number of brown 

 cystidia or seta?, in the hymenium, which project above the surface of the gills. 

 They are so numerous and so near the edge of the gills that they give these a 

 downy appearance. The quality of this species is even better than L. volemus, 

 though it is not as abundant here as the latter. Found in thin woods from August 

 to September. The photograph, Figure 141, was made by Prof. H. C. Beardslee. 



Lactarius volemus. Fr. 

 The Orange-Brown Lactarius. Edible. 



Volemus from volema pira, a kind of a pear, so called from the shape of the 

 stem. The pileus is broad, flesh thick, compact, rigid, plane*, then expanded, obtuse, 

 dry, golden-tawny, at length somewhat wrinkly. 



The gills are crowded, adnate or slightly decurrcnt. white, then yellowish; 

 milk copious, sweet. 



The stem is solid, hard, blunt, generally curved like a pear-stem ; its color is 

 that of the pileus but a shade lighter. Spores globose, white.
