19181 The Lactarias of JSToeth Carolina 15 



1877. Sandy soil in path by branch north of Meeting of the Waters, Septem- 

 ber 27, 1915. This is L. deceptivus, but is distinguislied from the 

 usual form by the entire absence of tomentum on the margin at all 

 ages, by the closer and narrower gills. The smooth margin is proba- 

 bly due to the very dry weather. 



2831. Low, damp deciduous woods at foot of Lone Pine Hill, September 14, 

 1917. Photo. Nearly white, but soon with huffy stains, old wounds 

 changing to buffy-cinnamon. Spores strongly warted, 6.6-7.8 x 9-llu,.
