Mycologia 



white, firm, soon slightly peppery, without special odor ; lamellae 

 white, heterophyllous, some forking part way to the margin or 

 near the stipe, narrowed at each end, slightly decurrent, about 5 

 mm. wide at the center, close ; stipe white, firm, spongy-stuffed, 

 nearly equal, 5.5-7 cm. X 2-2.2 cm., sometimes pruinose at the 

 apex ; spores pure-white, ellipsoid, minutely echinulate with blunt, 

 short projections, 6.25-6.87 X 8.75-9.37 /*. 



Type Locality: Newfane Hill, Vermont, 1,600 ft. elevation. 



Habitat : In woods usually under maple, birch, or oak trees, 

 July and the early part of August. 



Distribution : Newfane Hill, Vermont, and Magnetewan, 

 Ontario, Canada. 



This species resembles R. variata, R. heterophylla, and R. bifida 

 in certain respects. It differs from R. variata in its heterophyl- 

 lous lamellae which seldom fork more than once. R. variata has 

 a few short lamellae irregularly placed and the lamellae fork 

 from two to three times. From R. bifida it differs in its acrid 

 taste, less forking and thinner lamellae, and in the vinous shades 

 on the pileus. From R. heterophylla it differs in its acrid taste. 

 This is probably widely distributed and because of its close re- 

 semblance in the color of the pileus to that of R. variata, or in its 

 green form to R. heterophylla has been referred to one or the 

 other of the species. 



Russula ornaticeps sp. nov. 



Pileus convex-umbilicate, expanding when mature, with- mar- 

 gin drooping, at length somewhat infundibuliform in old age, up 

 to 10 cm. broad; surface variegated in color, Parma-violet, lilac- 

 mauve and bluish-violet intermingled with grayish-violet, the 

 lilac-mauve being usually in the center, surrounded by the indigo 

 with bluish-violet on the margin, covered with a pruinose bloom, 

 viscid when wet, the pellicle separable half way to the center ; 

 margin even, when young, somewhat striate-tuberculate when 

 mature ; context white, except next the cuticle, where it is tinged 

 with the surface color, mild then slowly slightly acrid in and next 

 the cuticle ; lamellae fleshy-white, sometimes becoming rusty 

 spotted near the edge, equal, some forking near the stipe, venose- 

 connected, narrowed at the inner end, rounded at the outer, close ; 

 stipe white, occasionally washed with a faint tinge of violet, 

 sometimes pruinose at the apex, irregularly striate, nearly equal
