GENERA AND SPECIES OF MUSHROOMS 



Gills broad; rather far apart; adjacent to but not attached 

 to the stem (adnexed) ; white. 



Stem long and ending below in a long root-like prolongation 

 which penetrates the earth deeply; slender; firm; generally 

 tapering upward; pithy (stuffed); 2 to 8 inches long above the 

 surface of the ground; whitish or color of the cap. 



Spores white; elliptic with a slight oblique spur at one end; 

 .0006-.0007 of an inch long, .0004-. 0005 inches broad. 



The rooted collybia is a common species and one easily 

 recognized if notice is taken of the lower part of the stem. 

 This is a long slender tap-root tapering downward and gener- 

 ally penetrating the earth to a depth about equal to the length 

 of the stem above the surface. The stem is generally thickest 

 at the surface of the ground and tapers slightly from this point 

 in both directions. 



After long exposure the spores sometimes assume a yellowish 

 color. 



The caps are somewhat tough but agreeable in flavor, and 

 the species is classed as an edible one without any hesitation.
