GENERA AND SPECIES OF MUSHROOMS 



The species of this reddish-brown genus are usually of 

 small size, thin, soft and fleshy and are especially distin- 

 guished by their having the stem attached to the margin of 

 the cap. In some specimens the stem is missing and the cap 

 is attached by its margin to the decayed or dead wood upon 

 v/hich it grows. The cap is resupinate (attached by its top 

 surface) or shelving, lying flat or nearly so, upon the wood. 

 The genus resembles pleurotus among the white-spored mush- 

 rooms, or Claudopus among the rosy-spored ones. Atkinson.
