often forked at the base, and with shorter ones intermixed, 

 whitish ; stem about l|r in. long, solid, firm, nsually attenuate

Bussula dejKillens, Fries, Epicr,, p. 353 ; Cke., Hdbk., p. 

 323; Cke., Illustr., pi. 1021. 



In woods, Szo. 



Smell none, taste mild. Pileus sometimes deep crimson- 

 lake at first, becoming white, especially at the disc ; stem 

 pure white at first, then grey. Differs from B. dccolorans 

 in the white gills. 



Russula cyanoxantha. Schaeff. 



Taste mild. Pileus 2-4: in. across, convex then plane, at 

 length depressed or infundibuliform, sometimes even, at 

 others rugulose or virgate, viscid, margin bent down, then 

 expanded, remotely and slightly striate, colour very variable, 

 in the typical form lilac or purplish to olive-green, disc 

 usually becoming pale and often yellowish ; margin gene- 

 rally bluish or livid-purplish; flesh firm, cheesy, white, 

 usually reddish below the separable cuticle ; gills somewhat 

 rounded behind, connected by veins, slightly crowded, 

 broad, mixed with forked and shorter ones, shining white ; 

 stem 2-3 in. long, up to 1 in. thick, equal, glabrous, 

 even, white ; spongily stuffed, but firm, often cavernous 

 inside when old ; spores 8-9 // ; cystidia numerous, pointed. 



Agaricus cyanoxantha, Schaffer. 



Bussula cyanoxantha, Fr., Monogr.,ii. p. 194; Cke., Hdbk., 

 p. 328; Cke., Illustr., pL, 1043, 1076, and 1077. 



Taste mild, pleasant, and in this respect allied to B. vesca, 

 but in the last named the colour of the pileus is constant, 

 whereas in the f)i"esent the colour is very variable ; this, 

 and other points of difference are constant. When old the 

 pileus is sometimes pallid, greenish- white, but mixed with 

 purple. (Fries.) 



The broad, rather distant gills wdth numerous projecting, 

 pointed cystidia, separate the present species from B. hetero- 

 phijlla. B. vesca differs distinctly in the reticulately rugu- 

 lose stem. B. furcata differs in the adnato-decurrent, 

 thickish gills, and in becoming slightly acrid in the mouth, 

 although mild at first.
