74 FUNGUS-FLOEA. 



slightly striate wlien old ; gills adnexed then adnate, rather 

 narrowed behind, 2 lines broad in front, rather distant, 

 pallid then pale yellow; stem 2-3 in. long, | in. thick, 

 ■equal, almost even, firm, white, spongily stuffed; spores 

 globose, minutely echinulate, 9-10 /a diameter. 



Considered by Fries as a variety of U. emetica, from which 

 it differs entirely in those characters which more especially , 

 ■characterise the last-named — free, persistently pure white 

 gills. The points of the present are : acrid taste, deep red 

 pileus, and pale yellow, naked gills. ' 



Russula rosacea. Fr.

 varying in depth, often with darker spots, whitish in places 

 where the cuticle has disappeared; gills adnate in every

In woods. 



Allied to B,. sanguinea, but differs in being irregular, often 

 •excentrio, pileus rather wavy, scarcely depressed ; gills less 

 ■crowded, broader, less divided, and hardly connected. Some- 

 times pale flesh-colour, becoming pale and marked with 

 darker spots. (Fries.) 



Distinguished from similarly coloured species by the thick 

 flesh and persistently white adnate gills. Slowly becoming

Russula sanguinea. Fr. 

 Acrid. Pileus 2-4 in. across, flesh thick, cheesy, white;

 base of the depression usually gibbous, polished, even, moist 

 in wet weather, blood-red, usually becoming pale at the
