MYCENA. 49 



Straight and pressed close to the stem. Gills not decurrent, 

 distinguished from the other cartilaginous by the margin of 

 the pileus, never involute, and from the pileus being umbonate. 

 I have only few determined species ; on account of their small 

 size they are as a general thing overlooked.
