CLASSIFICATION 125 



R. littcotacta. — Cap convex, then plane and subumbonate, 

 wrinkled, carmine-scarlet, becoming whitish at the striate edge, 

 up to 2 in. across ; flesh white, red under the cuticle, stained yel- 

 lowish when bruised ; gills adnate, forked, pale straw-colour, 

 yellow when bruised ; stem equal or slightly tapering downwards, 

 wrinkled, white tinged with lilac, yellowish when bruised, up to 

 2 in. long. 



Characterized by the flesh becoming tinged yellow when cut or 

 bruised. Taste acrid. 



On the ground under trees. 



Mycena 



Pileus regular, thin, usually striate or fluted, campanulate or 

 bell-shaped, almost cylindrical when young, and with the margin 

 of the pileus straight and pressed flat to the stem ; stem central, 

 hollow ; gills adnate or adnexed, often with a decurrent tooth 

 slightly running down the stem, white, or tinged grey or pink. 



Most of the species are small and delicate, often brightly coloured, 

 and sometimes strong-scented. The margin of the gills often differs 

 in colour from the rest of the gill. Growing on wood, twigs, dead 

 leaves, etc. ; some grow in the ground. 



Collybia differs in the edge of the pileus being incurved in the 

 young stage. 



For facility of determination the species are grouped under the 

 following sections : — 



Ladipedes 



Stem rooting, giving out a white or coloured juice or milk when 

 broken. 



Calodontes 



Gihs having the edge distinctly darker and differently coloured 

 to the remainder. 



Glutinipedcs 



Stem distinctly viscid or glutinous. 



Basipedes 

 Stem attached by a small flattened disc or bulb at the base. 



Siccipedes 

 This somewhat extensive section of the genus Mycena is mainly 

 distinguished by negative characters. The members are devoid of 

 any of the features respectively characteristic of the foregoing 

 sections. The stem is always dry, contains no milky juice and no 

 bulb at the base ; the margin of the gills is not different in colour 

 from the remainder. The species vary much in size, some being the 

 largest and others amongst the smallest included in the genus. 

 Gills white or often grey ; stem Arm and rigid or very slender and 

 weak, usually considerably elongated.
