EMETIC RUSSULA 



Pileus fleshy, firm becoming fragile, convex becoming plane or 

 centrally depressed, glabrous, viscid when moist, striate sulcate on 

 the margin, rosy or blood-red, sometimes white or fading to white, 

 flesh white, reddish under the separable pellicle, taste very acrid ; 

 lamellae equal, broad, subdistant, rounded behind and free or nearly 

 so, white ; stem solid or spongy within, elastic when young, becoming 

 fragile, even, white or tinged with red; spores white, globose, 

 .0003-.0004 of an inch broad. 



Pileus 2-4 inches broad; stem 1.5-3 iiiches long, 3-6 lines thick. 



Woods and swamps. Common. July to September. 



This russula has a very acrid or peppery taste and is generally 

 considered poisonous by European mycologists, but deemed edible 

 and harmless by some American mycophagists. Thorough cooking 

 probably destroys its harmful properties. I have not tried it.
