MYCEXA 



This genus differs from Collybia in having the margin of the cap straight 

 in the yotmg plant instead of incurved. It is separated from O m p h a 1 i a by the 

 insertion of the gills, ^\■hich are adnate or adnexed but never decurrent and by 

 the conic or bell-shaped cap. These are typically small graceful plants, often of 

 most beautiful coloring. It is probable that all the species are edible, but they are 

 usually neglected on account of the small size. The name means mushroom.
