Coprinus micaeeus, Fries, Epicr., p. 247 ; Cke., Hdbk., 

 p. 229 ; Cke., lUustr., pi. 673. 



About old stumps, posts, &c. Generally densely fascicu- 

 late. In rainy weather subdeliqnescent, pileus soon naked, 

 and becoming dark reddish-brown. In dry weather the 

 pileus becomes pale in colour, and the glistening particles 

 of lime, which resemble mica in their appearance, are per- 

 manent. 



Caespitose ; pileus f-1 in. or more broad, half-ovate, often 

 more or less irregular from the dense mode of growth, 

 sprinkled with glistening meal, strongly striate, almost 

 plicate, rufous, the umbo darker ; the margin cinereous, very 

 thin ; veil very fugacious. Gills attenuated in front, broad 

 behind, ascending, attached above, umber mottled with the 

 sporules, which appear black when viewed in the mass, but 

 are really brown-purple ; stem. 2-3 in. high or more, 2 lines 

 thick, hollow, brittle, squamuloso-pulverulent, the epidermis 

 often cracked into little scales, very faintly tinged with red, 

 attenuated upwards. (Berk.)

 either end, attached, then seceding and becoming free, deep 

 rich brown, then black ; stem 4-j in. high, 2-3 lines thick, 

 attenuated upwards, slightly bulbous at the base, snow-

 resembling Coprinus micaeeus in habit, but larger and umber-
