Fungi with Gills 
GENUS OMPHALIA 
The members of this genus have white spores, and the gills 
growing down onthe stem. They have a hard, tough rind to the 
stem, which distinguishes them from the genus Cilitocybe, which 
has fleshy stems. Omphalia umbellifera is a small species, with 
a cap about an inch broad. Itis the common mushroom on the 
top of Mount Marcy, the highest mountain in the State of New 
York. 
GENUS RUSSULA 
The genus Russula may usually be recognised by its brittle 
character, added to its fleshy stem and the fact that the lamelle 
are usually joined to the stem. Bright clear reds and purplish 
hues prevail, but several species exhibit a green colour, or an 
approach to green. The spores are white or yellowish, and the 
flesh never exudes a milky or coloured juice.
