Pileus 5-10 cm broad ; stem 4-10 cm long, 6-12 mm thick. 



Ground in woods and in swamps. Old Forge, Herkimer co. 

 August. F. S. Boughton. North Elba. September. C. H. Peck. 



Closely allied to Lactarius rufus (Scop.) Fr. but sepa- 

 rated by its paler lamellae, hollow stem, absence of an umbo and 

 very scanty milk. The stem is often pointed at the base. Edible 

 according to F. S. Boughton, who says it " entirely lost its acridity 

 in cooking and was very fine in flavor." I have not tried it.
