yellow, equal, venose connected, rarely forking next to the stipe, 
rounded at the outer end, narrowly adnate at the inner end, sub- 
distant, rather broad; stipe chalk-white, unchanging in drying, 
nearly equal, firm, stuffed, then tending to become hollow, gla- 
brous ; spores pale-yellow, echinulate, some globose, but many 
ellipsoid, lo X 
Type collected in fir forests with scattered specimens of oak, 
birch, willow, and maple, November 6, 1911, Corvallis, Oregon, 
JV. A. Murrill p6^. This species resembles Russula asurea Bres., 
but differs in the color of the pileus and the lamellae, which in 
R. azurea are white and remain white. It is a beautiful plant, 
characterized by its violet cap and pure-white stem. It is to be 
hoped that other collections of this species will soon be made and 
the taste recorded.
