 Stem, solid, dirty white or yellowish. 

 Pileus two to four inches broad. 



Scarce. Found specimens in Bastian's open wood. 



Genus V. CI^ITOCYBB. 



From Clitos, a declivity, and Cibe, a. head. 



This is the first genus wnth decurrent gills and a fleshy stem- 

 Fries has the following definition : Universal veil, when> 

 present, is only frost-like, generally obsolete. Stem w^ith a 

 spongy pith, somewhat elastic. Margin more or less involute. 

 The gill-bearing receptacle (hymenophore) quite continuous, 

 owing to the apex of the stem being dilated. Gills running down 

 the stem in an attenuated form, acute, never sinuate as in the 

 Tricholoma. All growing on the ground, plant depressed in 

 the center or (infundibuliform) funnel form. The thinner 

 species are late, and stand low temperature. Many are 

 remarkable for their fragrance. Few are edible. 



The species are divided into two sections, the dry and 

 watery (hygrophanousj. To tell a hj^grophanous specimen 

 from a dry one is to make a section of the specimen. If it is 

 watery and assumes a different color when dry, it is hygro- 

 phanous.

Pileus, pale, tan color, fleshy at disc, convex, depressed,, 

 involute, margin even, flesh soft, white. 



Gills, very decurrent, thin, close, soft, white.
