Easily distinguished bj the change "i color when bruised. Tlii^ 

 change is due to lactiferous tubes containing ;i juice which turns 

 blackish on exposure to the air. These tubes are specialized byphae 

 interspersed throughout the trama <>i the pileus, gills and stem. 

 I ader the microscope ii maj !"■ seen that the pubescence is com 

 posed of elongated hyaline cells. The presence of b juice which 

 exudes <>n wounding the planl is unusual in this genus, and re 

 minds one of a section of the genus Mycena; but the incurved 

 margin of the young pileus indicates its relationship with Collybia.
