APPENDIX XI 743 



Cap 3 to 4 inches broad; stem 2^2 to 4 inches long. 



Russula emetica is a handsome plant of wide distribution found during summer 

 and autumn on the ground in woods or open places. Although some enthusiastic 

 mycophagists testify to its edibility, it is best to consider the species poisonous. 



Russula ochrophylla 



Cap convex, becoming nearly plane or very slightly depressed in the center, when 

 old purple or purplish red, margin even, sometimes faintly striate when old; flesh 

 white, purplish under the cuticle; gills adnate, entire, a few forked at the base, inter- 

 spaces somewhat venose, at first yellowish, ochraceous buff when mature, powdery 

 from the spores; stem mostly equal, solid or spongy within, rosy or red, paler than 

 the cap. 



Cap 2 to 4 inches broad; stem 2^^ to 3 Inches long. 



Russula ochrophylla may be found growing singly, or in small patches on the 

 ground in woods, mostly under trees, according to Prof. Peck, especially under oak 

 trees. In Virginia, Maryland, and the District of Columbia it is abundant in July 

 and August and is to be found less frequently in September and the first part of 

 October. 



Russula roscipcs {Edible) 



Cap conve.x, sometimes plane or slightly depressed, at first viscid, then dry and 

 faintly striate on the margin, rosy red, frequently modified by pink or ochraceous 

 shades; gills moderately close, ventricose, more or less adnate, whitish becoming 

 yellow; stem stout, stuffed or somewhat hollow, white tinged with red. 



Cap I to 2 inches broad; stem i3'^ to 3 inches long. 



This species grows on the ground in mixed, but generally coniferous, woods. It 

 appears in the late summer and autumn and is reported excellent, though, as already 

 stated, the amateur should be cautious and avoid all red species of this genus. 



Russula rubra 



Cap convex, flattened, finally depressed, dry, pellicle absent, polished, cinnabar 

 red, becoming tan when old; flesh white, reddish under the cuticle; gills adnate, 

 somewhat crowded, whitish then yellowish, often red on the edge; stem stout, solid, 

 varying white or red. 



Cap 2% to 4 inches broad; stem 2 to 3 inches long, about i inch thick. 



This species is extremely acrid, and, as there are conflicting opinions concerning 

 its edibility, it is best for the amateur to refrain from collecting it. It is found in 

 woods on the ground in summer and autumn. 



Russula viresccns {Edible) . 



Cap at first rounded, then expanded, when old somewhat depressed in the center, 

 dry, green, the surface broken up into quite regular, more or less angular areas of 

 deeper color, margin straight, obtuse, even; gills adnate, somewhat crowded, equal 

 or forked; stem equal, thick, solid or spongy rivulose, white.
