J91S'] The Lactarias of ]N'orth Carolina 47 



''Distinguishing Field-Marks : The gray, tomentose, azonate, 

 expallent pileus, the glabrous stem, and the hick of odor. While the 

 plants may be dark-gray at first, they usually become dull-yellowish or 

 putty-colored when mature. This species is closely related to L. mam- 

 mosa Fr., a European plant which has not been found in the United 

 States. As figured by Fries, L. mammosa is a larger stouter plant 

 than L. grisea, it does not become yellowish with age, and it has a 

 white pubescence on the margin of the young pileus, and the stem is 

 pubescent. L. grisea is at first uniformly gray and covered with 

 gray tomentum, which later becomes floccose and less evident."
