1918^ The Lactarias of ]!^orth Carolina 13 



A large, brittle, deeply infundibuliform plant with velvety cap and 

 stem, distant, cream-colored gills, and white, acrid milk, which slowly 

 changes to olive and then deeper. It is most like L. vellereiis and 

 L. subvellereus Pk., but is easily distinguished by its decided color, 

 milk turning olive gTeen then red-brown on exposure, veined gills, 

 lavender pink tint of stem surface and cut flesh. The dried plants 

 of all the collections are distinctive in appearance and are unlike 

 specimens of any form of L. subvellereus or of L. vellereus, particu- 

 larly in regard to the stem, which is whitish and not rich buff or 

 cinnamon and lacks the smooth velvety appearance of the others. 

 The dried gills are a dark reddish-brown with a dull olive tint and 

 are often very glaucous from the spores. 



I take pleasure in naming this species for Mr. H. A. Allard, my 



first assistant in botany, who is now with the U. S. Department of 



Agriculture.
