and much tufted, but individuals of the same species occur 

 solitary and on the ground. 



YTTT. Adonideae. 



Stem without juice and not discoid at the base ; gills all 

 one colour, margin not darker, colour not changing. Colour 

 pure, bright, not brownish nor greyish. 



Scattered or solitary, terrestrial. 



IX. Calodontes. 



Stem juiceless, not expanded at the base ; gills having the 

 edge distinctly darker than the rest, and minutely den-

 present section in having a dark edge, but the stem contains 

 coloured juice or milk, and consequently is placed in section 

 Lactipedes.
