Fungi with Gills 



GENUS OMPHALIA 



The members of this genus have white spores, and the gills 

 growing down on the stem. They have a hard, tough rind to the 

 stem, which distinguishes them from the genus ClUocybe, which 

 has fleshy stems. Omphalia umbellifera is a small species, with 

 a cap about an inch broad. It is 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 lamellae 

 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, and the flesh never 

 exudes a milky nor coloured juice.
