1918'] The Lactarias of ISTorth Carolina 9 



surface white, minutely soft-tomentose, the white tomentum often 

 missing in areas, sometimes over a large part of the stem (such places 

 are smooth and show the brownish tan sub-layer). 



Spores (of No. 1585) oval or slightly elliptical, very minutely 

 tuberculate, or some seem smooth, G.G-7.5 x 7.5-9. 5/a. Cystidia cylin- 

 drical, often with a point or knob. 



A large species, usually white all over except for yellowish discol- 

 orations in age. Dried plants are a rich buff or buffy cinnamon, the 

 stem often darkest ; the gills reddish brown and glaucous. It may be 

 distinguished from all others near it, except L. siibvellereus and L. 

 Allardii by its tomentose cap and stem. It is very common in woods 

 in summer, more common at times even than L. piperatus, L. perga- 

 menus, and L. deceptivus. The latter, which has a tomentose stem, is 

 easily distinguished by the conspicuously rough spores and lighter 

 color of all parts when dry. Miss Burlingham also mentions the 

 occurrence at times of yellowish latex in this species as recorded by 

 Earl and by Massee.
