Mycologia 



tiful when growing, but rather difficult to find on acount of its 

 color. The peppery taste seems to be confined to the cuticle or 

 the context adjacent, and becomes perceptible after thorough 

 chewing. In color this resembles R. cyanoxantha but differs in 

 the slight peppery taste, the equal lamellae, and the absence of 

 cystidia. From R. heterophylla it differs also in the color of the 

 spores. The beauty is lost in drying. 



Russula viridi-oculata sp. nov. 



Pileus fleshy, thin, soon plane, from 2.3-6 cm. broad; surface 

 dark dull-green (264 — t. 4) or darker blue-green in the center, 

 shading to dull sage-green (278 — t. 1) on the margin, fading 

 with age to greenish-white (15 — t. 1) toward the margin, viscid 

 when moist, cuticle separable, slightly pruinose when young ; 

 margin even, recurved at first, extended when mature ; context 

 white; unchanging, peppery, slightly pungent, with the odor of 

 green apples when fresh ; lamellae white, equal, a few forking 

 next the stipe, rounded and free, broad throughout, powdered 

 somewhat with spores ; stipe white, spongy, glabrous, equal, 5 

 cm. X I-I.2 cm.; spores white, broadly ellipsoid, uniguttulate, 

 apiculate, minutely echinulate. 



Type Locality: Newfane Hill, Vermont, 1,500 ft. elevation. 

 Habitat : Under a group of pines in' mixed woods, July 28, 

 1919. 



This may be distinguished from R. acruginca by the promptly 

 acrid taste. It differs from R. rcdolcns in taste as well as in 

 odor and color and in the spore markings. It is smaller than R. 

 variata and differs in the lamellae forking only near the stipe. It 

 is also a small delicate mushroom more like R. fragiliformis in 

 size and texture. 



Russula Hibbardae sp. nov. 



Pileus fleshy, broadly convex, then plane to depressed, up to 

 10.5 cm. broad; surface vinous-purple to slate-violet on a back- 

 ground of Naples-yellow, unevenly colored, sometimes yellow 

 with only a wash of slate-violet in places, pruinose-velvety, vis- 

 cid when wet, but soon dry, cuticle separable nearly half way to 

 the center ; margin even or slightly striate-tuberculate on extreme 

 edge; context white, unchanging, slowly becoming slightly pep- 

 pery, without special odor ; lamellae nearly white, then maize-
