GENERA AND SPECIES OF MUSHROOMS 



Crepidotus versutus; evasive agaric. Species 48. Fig- 

 ure 16. 



On decayed wood. 



Cap at first attached by its top surface (resupinate), later 

 bent or turned over; kidney-shaped or divided into two por- 

 tions; stemless; white; clothed with a soft down; margin curved 

 in; V3 to I inch broad. 



Gills rather broad and far apart ; rounded at the base of the 

 cap; radiating from a lateral point on the cap; whitish, turning 

 rusty when old. 



Stem absent. 



Spores rusty; nearly elliptic; .00035 to .0004 inches long by 

 .00025 to .0003 inch broad. 



This little crepidotus has a pure white cap which is covered 

 with a soft white down. The plants grow usually on the 

 under side of rotten wood or bark and then the upper side of 

 the cap lies against the wood, and is said to be resupinate. 

 Sometimes when they grow toward the side of the log the cap 

 has a tendency to be shelving. In the resupinate forms the 

 cap is usually attached to the wood near one edge. Atkinson. 



The genus Entoloma 



The stems of mushrooms belonging to this genus have 

 neither ring nor cup. The gills are attached to the stem and 

 sometimes extend down it and become pink when old by being 

 dusted with the rosy-colored spores. In this respect the plants 

 might be confused with specimens of the genus Agaricus. As 

 many of the Entolomas are poisonous, the error might have 

 serious consequences. The point of difference is that in the 

 edible mushrooms of the genus Agaricus, the gills are pink 

 when the plant is young and grow brown and then black as 

 the plant ages, while in the Entolomas, on the other hand, the 

 gills remain pink to the last.
