Leucosporae 



mens were proliferous. The umbo had developed into a minute pileus. Lactarius. 

 With us the prevailing color of the pileus is yellowish-red or cinnamon- 

 red. Sometimes the color is almost the same as that of L. volemus 

 and L. hygrophoroides, and again it is a tan-color or a bay-red, as in 

 L. camphoratus, from which such specimens are scarcely separable, ex- 

 cept by their lack of odor. In young plants the pileus usually has a 

 moist appearance, which is sometimes retained in maturity. Cordier 

 pronounces the species edible, and says that he has tested it several 

 times without inconvenience. Peck, 38th Rep. N. Y. State Bot. 



Spores ion Cooke; //A W.G.S. 



West Virginia mountains, 1881-1885; Pennsylvania, New Jersey, 

 everywhere on moist ground. July to October. Mcllvaine. 



Edible. Curtis. 



The description of Fries as enlarged and modified by Professor Peck, 

 together with that of the varieties placed to the credit of the species by 

 Gillet, are given above in full. The species with its ascribed varieties 

 is common and well known. Var. ba dins occurs in West Virginia and 

 Pennsylvania. They are all edible and vary but little in quality. 

 L. subdulcis requires long cooking. 



L. muta'bilis Pk. changeable. Pileus 2-4 in. broad, thin, convex 

 or nearly plane, zonate when moist, reddish-brown, the disk and zones 

 darker, zoneless when dry, flesh colored like the pileus. Milk sparse, 

 white, taste mild. Gills narrow, close, adnate, whitish, with a yellow- 

 ish or cream-colored tint when old. Stem 1-2 in. long, 3-5 lines thick, 

 equal or tapering upward, stuffed or spongy within, glabrous, colored 

 like the pileus. Spores subglobose, rough, 7 .6p- broad. 



Low, damp places. Selkirk and Yaphank, N. Y. June and Sep- 

 tember. 



The species is allied to L. subdulcis, from which the larger size and 

 zonate pileus separate it. The zones disappear in the dry plant, and 

 this change in the marking of the pileus suggests the specific name. 

 They appear to be formed by concentric series of more or less confluent 

 spots and are suggestive of such species as L. deliciosus and L. subpur- 

 pureus. Peck, 43d Rep. N. Y. State Bot. 



West Virginia, Pennsylvania. Solitary but frequent. In moist woods 

 and margins of woods. June to October. Mcllvaine.
