A CATALOGUE OF BEITISH POISONOUS FUNGI. 179 



Genus RVSSULA. 



Obs. The general facts regarding the poisons of this genus wfll be found in 

 chapter ix. — W. D. H. 



(XXXVII.) RUSSULA EMETICA ; The Sickener. 



Habitat. In woods, and under trees on lawns, etc. Scattered. 



Season. July to November. Common. 



Pileus. Two to five inches across, rosy, then blood-red, per- 

 haps becoming tawny, ochraceous, or pale ; polished, viscid in 

 wet, smooth ; convex, then plane, depressed. Cuticle separable. 

 Margin thin, patent, at length striate. 



Stem. Two to three inches high, white, flushed with rose, 

 thickish, elastic, smooth or sub-rugulose, naked, blunt. 



Section. Flesh fragile, not thick, white, rosy where snail-eaten. 

 Stem solid, spongy. Gills white, equal, broad, distant, brittle, 

 thickish, simple, veined beneath, fi^ee. Odour slight. Taste pun- 

 gent. Spores white. 



Obs. The poison is very irritant and rapid in action ; it has some after- 

 tendency to induce nervous disorder as well. Krapf found that it was not 

 separable either by boiling or drying the mushroom. Yet I have heard of this 

 species having been eaten, probably after treatment with vinegar. — W. D. H. 



(XXXVIII.) RUSSULA FRAGILIS ; The Sickener's Sister. 



^abitat. In woods and under trees. Singly. 



Season. September to November. Common. 



Pileus. One to two inches across, rose-red, perhaps becoming 

 ochraceous or pallid, opaque, sleek, viscid in wet ; convex, then 

 plane, depressed, unequal, thin, lax. Cuticle not separable. Mar- 

 gin striate, tuberculose. 



Stem. One to two inches high, white, glossy, not stout, finely 

 striate, nearly equal, naked, blunt. 



Section. Flesh thin, fragile, white. Stem stuffed, then fistu- 

 lose. Gills white, crowded, thin, equal, ventricose, sub-serrulate, 

 adnate. Odour faint. Taste pungent. Spores white. 



Obs. It appears to be equally as poisonous as E. emetica, and is very like it. 

 The principle exerts the same action. But Barla says the poison of this species 

 can be extracted by boiling. — W. D. H. 



(XXXIX.) RUSSULA OCHROLEUCA ; The Brazen-face. 

 Habitat. In damp parts of woods, especially under pine and fir. 

 Scattered.
