A CATALOGUE OF BRITISH POISONOUS FUNGI. 181 



white, numerous, thin, narrow, sub-serrulate, furcate, equal, 

 pointed at both ends, sub-decurrent. Odour feeble. Taste bitter 

 and pungent. Spores white. 



Obs. It seems to contain an irritant principle, but in slight degree, and 

 which is separable by boiling, etc. It is reported to be commonly eaten in the 

 south of France, and I think I have eaten it myself. Yet in maturity it would 

 be hurtful, if eaten unprepared and to any appreciable extent. — W. D. H. 



(XLII.) RUSSULA SARDONIA ; The Malignant. 



Habitat. On bare ground in woods. Singly. 



Season. August to November. Not uncommon. 



Pileus. Two to three inches across, bulf, or buff and red, or 

 yellowish, tint changing as it develops, smooth, opaque, viscid ; 

 convex, then plane, depx'essed. Cuticle thin, adnate. Margin 

 even, smooth. 



Stem. One to two inches high, white, perhaps touched with red, 

 stout, enlarged above, smooth, naked, blunt. 



Section. Flesh white, thick, compact. Stem solid, spongy. 

 Gills white, yellowish at length, numerous, narrow, equal, furcate, 

 adnate. Odour slight. Taste sparingly acrid. Spores pallid. 



Obs. It is said to be poisonous in high degree, probably narcotico-acrid. I 

 once found a specimen growing conjoined to a Chantarelle — a curious instance, 

 which shows that care is always needful. There are other Russules to which 

 poisonous properties have been ascribed, but the above are all I can find that 

 have been circumstantially proved to be so. — W. D. U.
